A family of approximately 29 genera and 600 species, Oleaceae are cosmopolitan but occur in great diversity in temperature and tropical Asia. Some of the largely represented genera of olive family and their approximately
reported species are Jasminum (300), Chionanthus (125), Linociera (80), Fraxinus (70), Ligustrum (40), Syringa (30) and Olea (20).
Genus Jasminum contains 90 species to be true in existence and use, range from landscape to hair adornments, and perfumes. It is native to Indo-Malayan region. Morphological variants from different species have been developed in different regions in India. Jasmines are one of the most important ornamental flowering plants, widely cultivated for their attractive and fragrant flowers. Jasmine has multiple uses like in the making of bouquets, garlands, decorating women’s hair as veni, beautifying pandals and marriage halls and the like, besides preparation of perfumes and cosmetics. Jasminum grandiflorum is highly priced for high grade perfumes throughout the world. Jasmine oil has a significant place as an ingredient in cosmetics, confectionary, ointments, disinfectants and detergents and in pharmaceutical beverages. The word ‘jasmine’ has been derived from a Persian name ‘Yasmun’ meaning fragrance.

Orchidaceae is one of the largest families of the flowering plants, represented by about 1,000 genera and 20,000 species which are cosmopolitan but primarily distributed in tropical areas. They are found in all parts of the world, even in the frozen areas of Alaska, the snow-covered areas of the Himalayas and sandy deserts of Australia and Africa. New Guinea has more orchids, native to the island, than any other part of the world. In Indian flora, this is the second largest family having 7% of the world’s orchid genetic diversity contributing 1,330 species in 186 genera distributed mainly in Eastern Himalayas, Western Ghats and Khasi hills. Indian orchid wealth serves as a foundation of world’s orchid industry. The North-Eastern hilly regions of India, Himalayas being the cradle, comprises eight states- Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura- is the abode of unique orchids. Many are now endangered due to man’s invasion and “burn and grow” type of shifting cultivation. Arunachal Pradesh alone accounts for 601 species, almost 52% of the total species known in India. Arunachal’s rich and colourful orchids find a place of pride. Arunachal Pradesh is called the ‘Orchid Paradise of India’. The entire orchid family with about 601 species in Arunachal Pradesh is classified into six sub-families, 17 tribes, 24 sub-tribes and 111 genera. Vanda is found as epiphyte on mango and other trees in the plains. Aerides is found in southern and northern parts of India, Burma, Malaya and Indonesia, Vanda spp. is common in India, Sri Lanka, South East Asia and Indonesia. Calanthe spp. have a wide range from China, Japan, Vietnam to Australia, Southern parts of India and South Africa. The striking Cattleya spp. are found only in South America. Coelogyne, a genus of considerable horticultural value, is mostly represented in Nepal and Sikkim but several species are found in Bhutan and upper Myanmar, China, South-East Asia, the Philippines and Fiji. About 20% of recorded Indian taxa are endemic. Dendrobium peguanum is a rare species, Rhizanthella gardneri is endemic to Western Australia which grows underground and Phaius tankervilliae (Nun’s orchid of Assam; 2n= 50) is also an endangered orchid. India has two conservation and germplasm centers at Shillong in Meghalaya and Yercaud in Tamil Nadu. Asia’s largest orchidarium is situated at Tipi, Arunachal Pradesh while orchids sanctuary is situated at Sikkim.

A family of about 90 genera and 3,000 species distributed in both tropical and temperate regions. Central and South America are the chief centres of distribution where over 40 genera are found. About 15 genera and over 90
species have been reported from India. Some of the larger genera along with their approximately world over reported species (Hickey and King, 1988) are Solanum (1700), Cestrum (150), Physalis (100), Lycium (80-90), Nicotiana (66), Capsicum (50), Petunia (40), Hyoscyamus (20) and Datura (10). Solanum tuberosum (potato) and Nicotiana tabacum (tobacco) are the two most utilized plants of Solanaceae.
Petunias, popular bedding plants, with variety of forms, sizes and shapes are employed for landscape planning, garden designs and container gardening. The numerous phenotypes viz., Grandifloras, Multifloras, Millifloras, Waves, Hedgifloras, etc. are complex hybrids. The outstanding marketable series of P. x hybrida have been developed for upright, spreading and semi-trailing to trailing habits.
Selected Indian Genera
Atropa, Capsicum, Cestrum, Datura, Nicotiana, Petunia, Physalis, Solanum, Withania.

A family of about 86 genera and 3,000 species distributed chiefly in tropics and sub-tropics. About 22 genera and over 30 species have been reported from India. Some of the genera along with their number of approximately reported species and common names of them are Clerodendron (400, glory-flower), Verbena (250, vervain), Vitex (250, chaste tree), Lippia (220, Frogfruit), Lantana (150), Callicarpa (140, beauty-berry), Stachytarpheta (100) and Tectona (3, teak).
Verbena is popular ornamental plant suitable for flower gardens, hanging baskets, and balcony boxes. They are excellent both as ground cover for rockeries, and as bedding types. These plants abundantly flower in the seedin year and, thus, are grown as annual plants.
Selected Indian Genera
Clerodendron, Duranta, Lantana, Tectona, Verbena, Vitex.
Economic Importance
1. Timber yielding plants: Teak, one of the most famous timber-yielding plants of the world, belongs to Verbenaceae. It is used for high quality furnitures, heavy constructions, ship building, musical instruments and several other similar purposes. Some other timber-yielding plants are Gmelina arborea, Premna benghalensis and Vitex altissima.

DUS testing is a way of determining whether a newly bred variety differs from existing varieties within the same species, or the characteristics used to establish distinctness are expressed uniformly and that these characteristics do not change over subsequent generations. Testing the distinctness, uniformity and stability (DUS) of crop varieties is a statutory requirement before varieties can be entered into the Registers of Cultivars (National Lists) and/or granted Plant Breeders’ Rights (PBR). In India, Protection of Plant Varieties and Farmers’ Right (PPV&FR) Act (2001) provides the registration of new variety of plant if it conforms to the criteria of distinctness, uniformity and stability.
Why do we need a DUS test? New (candidate) varieties should be distinct from all other varieties whose existence is a matter of common knowledge, and also sufficiently uniform and stable with respect to the characteristics used to demonstrate distinctness. ‘Common knowledge’ is broadly defined to include all known varieties, i.e. any variety entered into or subject to an application for PBR, varieties grown commercially, held in publicly accessible reference collection, or of which there is a published description (UPOV 2002).
The responsibility for DUS testing of potato varieties in India lies with the ICAR-Central Potato Research Institute (CPRI), Shimla, which is the national institute for potato research and development. Currently a set of 51 DUS characters in potato are defined by CPRI and being used for distinguishing new variety.

Fruits contribute to nutritional security and thus are an important part of food system. To meet the future demand, development of varieties with improved yield and quality is the focus of researchers involved in fruit breeding. Though conventional breeding has resulted in the development of improved commercial varieties of different fruit crops, however conventional breeding is time consuming and faces several challenges due to long juvenile phase, highly heterozygous nature of most of the fruit crops. Challenges like changing climate, consumer preference, socio-economic conditions like reduced availability of land, labour and increasing cost of inputs, require fast and efficient methods to develop the varieties to meet the demands, which is not feasible with conventional breeding. Marker assisted breeding has given impetus to breeding efforts in several fruit crops, however it’s use is limited only for the traits controlled by a few major QTLs.
During last few years, enormous genomic resources have been developed for fruit crops using next generation sequencing technology. Such advances in genomic research in many fruit crops have paved the way for precision breeding using genomic assisted breeding (GAB) tools. GAB has helped in characterisation and utilisation of genome resources and using allele variation for cultivar development (Varshney et al. 2021). Advances in sequencing technology and affordability has allowed the genome wide analysis (GWAS) on diversity panels of different fruits resulting in identification of allelic variation associated with the traits of interest. Also, identification of superior alleles of candidate genes makes them amenable to genome editing based precision breeding. Genome wide genotyping and phenotyping offers tools for developing strategy for genomic selection (GS). Genomic selection relies on the prediction of breeding values of tested genotypes based on the large number of markers spread over entire genome. These tools promise to further improve breeding efficiency in fruit crops.

Introduction
Food preservation refers to an art or science which deals with the process of prevention of decay, deterioration or spoilage of food commodity to allow it to be stored in a safe condition for future use. All foods gradually undergo deterioration or spoilage from the time immediately they are harvested or manufactured. Some commodities spoil rapidly, while others can keep longer but for limited periods. The basic purposes of food preservation are:
1. Extension of shelf life of foods thus increasing the supply
2. Ensuring the availability of seasonal foods throughout the year
3. Adding variety to the diet
4. Saving time by reducing preparation time and energy
5. Stabilizing farm prices and prices of food
6. Improving the nutritional qualities The food spoilage can be caused due to growth and activity of micro-organisms, insects or rodents, action of enzymes, chemical reactions and physical changes that takes place during processing, drying, or freezing etc. Classification of Food Depending upon the type of spoilage and level of perishability, the foods are classified into three broad categories:

Introduction: Food processing involves different steps from receiving raw material, preparing for product manufacture, and packaging to storage. All these steps are called unit operations. They are broadly categorized as raw
material preparation (receiving, sorting, grading, washing, peeling, blanching, slicing, cutting, dicing etc), processing (canning, drying, pulping, juicing, product manufacture like jam, jelly, preserves, candies, pickling, sauce making, etc.) and post-production handling including packaging and storage. A brief detail about each unit operation is discussed as under:
1. Raw Material Handling
Material handling includes varied operations such as hand or mechanical harvesting on the farm, transportation in trucks or refrigerated vehicles of perishable produce to the market or to the processing plant or to store/godowns. For conveying, a wide variety of mechanical conveyors is used depending on the type of material. Common conveyors used in the processing plant include screw conveyors, bucket conveyors, belt conveyors and vibratory conveyors. Throughout these operations, care is taken to maintain sanitary conditions, minimize bruises and product loss, maintain raw material quality like physical appearance, and vitamin contents, minimize microbial growth and minimize other detrimental changes to the product quality during handling etc. It also includes other unit operations like receiving, cleaning/washing, sorting, grading, peeling, halving, slicing, blanching etc for preparation of fruit and vegetables for processing.

History of plant breeding
The process of plant breeding takes care of changing or modifying the genetically controlled characters of a particular variety or genotype of a crop. The practice of age-old agriculture uses the process of selection from the existing variability to save a particular quality of seed to grow better crops in the next harvest.
Gregor Mendel who is known as the father of Genetics discovered the law of segregation in the middle of the 1800s. This theory forms the base for the process of plant breeding. The primitive ways used for plant breeding are very different than what modern technology has contributed to the process of plant breeding during the 20th century.
Plant breeding is the science and art of purposeful manipulation of characters of crop species to create new varieties with a set of desired characteristics. Significance of plant breeding has been highlighted especially after the “Green Revolution”.

The term genome refers to a complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In the nucleus of each cell, the DNA molecule is packaged into thread like structures called chromosomes and each species has specific chromosome number. Most of the plants are diploid and they show in each one of its body cell, twice the number of haploid chromosomes (n) found in the gametes.
There are two main types of chromosomal variation that involve changes in the number. These are euploidy (in Greek “eu”means true or even and “ploid”means unit), which involves the variation of whole sets of chromosomes and aneuploidy(“aneu” means uneven), where a single chromosome within a set varies. This variation may be either increase or decrease in the chromosome number. The euploids include diploid (2n), triploid (3n), tetraploid (4n), hexaploid (6n) or even higher degree of polyploidy. Polyploidy, thus involves more than two genomes and is, therefore, a genometic mutation involving increase in the dose of whole genome. This condition of polyploidy is more common in angiosperms.

Bottle gourd, Lagenaria siceraria under the family Cucurbitaceae (Chromosome No: 2n = 2× = 22) is commonly grown vegetable crop of India, Africa, Central America and other warmer regions of the world. Tender fruits are widely used as cooked vegetables in a number of ways. Bottle gourd is a good source of vitamin C and zinc that may offer several skin benefits. It also contains minerals like calcium, magnesium, iron, and zinc. Its dietary fibre enhances gastro-intestinal health and promotes bowel movements and prevents constipation.
Origin, domestication and adaptation in India
It is the only crop known to have been cultivated in pre-Columbian times in both the Old and New World. Bottle gourd is indigenous to the tropical Africa. It has
bihemispheric distribution in Africa, the old world and America, the new World. Its utilization by man is about 16,000 years in the Old World and 12,000 years in the New World. It was independently domesticated in the two hemispheres. It was one of the world’s first cultivated plants grown not primarily for food, but for the use of hardshelled fruit as containers. The apparent wild plant produces thinner-walled fruit that, when dried, would not endure the rigors of use on long journeys as a water container. Today’s bottle gourd may owe it’s tough, waterproof wall to selection pressures over its long history of domestication. The bottle gourd was theorized to have drifted across the Atlantic Ocean from Africa to South America.

Crucifers, also known as Brassicas or cole crops, are a group of vegetables belonging to the family Brassicaceae (formerly Cruciferae). Common cruciferous vegetables include cabbage, cauliflower, broccoli, kale, mustard, turnip, and radish. These crops are widely grown around the world due to their nutritional value, economic importance, and adaptability to diverse climates.
However, crucifers are highly susceptible to a wide range of insect pests that can cause significant yield losses if not managed properly. These pests attack various parts of the plant, including leaves, stems, roots, and heads, leading to both quantitative and qualitative damage.
Distribution
Crocidolomia binotalis is widely distributed in India and is particularly prevalent in regions where cruciferous vegetables are cultivated. The pest is active from the third week of November to the fourth week of December, with varying population densities depending on environmental conditions (Pawar et al., 2010)

Distribution
Thrips tabaci is present in the central and southern regions of India, occupying about 36.4% of the land area under the current climate conditions. In central India, the states of Maharashtra, Karnataka, Madhya Pradesh, Gujarat, and parts of Rajasthan offer highly suitable habitats. In the northern region, areas such as Uttar Pradesh, Bihar, Jharkhand, Chhattisgarh, Delhi, Haryana, Punjab, Uttarakhand, & parts of the northeastern states are favorable. In southern India, Karnataka, Andhra Pradesh, Telangana, & Tamil Nadu are particularly suitable.
Biology Adults: Adult onion thrips overwinter in soil in onion, small grain, and hay fields. More mobile than immature stages, adults can fly and are attracted to white and yellow colours, often landing on clothing or skin. They are elongated, with body colour ranging from yellow to brown, and have pale, fringed wings. Adults measure 1.0–1.3 mm for females and 0.7 mm for males. Their lifespan is 16–42 days on garlic and 28–30 days on onion. Females lay eggs for up to three weeks after a one-week preoviposition period. In spring, adults emerge, colonize weed hosts, & can fly or be carried by wind to new plants.
Eggs
Females lay eggs individually in leaf tissue, with one end near the surface for immatures to emerge. The eggs are microscopic, kidney-shaped, and initially white or yellow, turning orange with reddish eye spots as they mature. On onion, eggs average 0.23 mm in length and 0.08 mm in width. The incubation period is 4–5 days on onion, with hatching occurring in 2–3 days in the lab, but 5–10 days in cooler field conditions.

Chilli (Capsicum annuum L.), a member of the Solanaceae, is a significant spice and vegetable crop in India, extensively cultivated over warm temperate, tropical, and subtropical regions. Approximately 51 insect pests and two mite species from 27 families and 9 orders were discovered to be infesting chillies (Reddy and Puttaswamy, 1983). The yield losses range from 50-90 per cent due to insect pests in chilli (Nelson and Natrajan, 1994)
Chilli thrips: Scirtothrips dorsalis, Thripidae, Thysanoptera Biology
The adults are slender, yellowish brown in colour, with long, narrow, and heavily fringed wings. The adult female inserts eggs into the tissues of the leaves and shoots. The nymphs are similar to adults, except they are smaller and wingless. With the exception of the rainy season, the pest is present all year round. The life cycle is completed over a period of two weeks. Over the course of a year, multiple generations overlap.
Recently introduced invasive thrips in chilly is Thrips parvispinus Karny. It causes premature flower drop, shedding of fruits and malformations resulting in severe yield loss. The average fecundity is about 56 eggs with a mean developmental period of 18.8 days (Muray et al., 2009).

Fruit borer: Helicoverpa armigera, Noctuidae, Lepidoptera
Biology: The adult females are light pale brownish-yellow stout moths while the male moths are pale greenish with V-shaped speck. The eggs are creamy white and sculptured type. They are laid singly. The larva shows colour variation from greenish to brown. It has dark brown grey lines on the body with lateral white lines and also has a dark band. Pupation occurs in soil, leaf, fruit, and crop debris.
Nature of damage and symptoms
• The young larvae feed on tender foliage
• Mature larvae bore into fruit through circular holes
• Larva thrust only a part of its body into fruit and eat the inner content

Gladiolus is a genus comprising around 260 species of perennial flowering plants in the iris family (Iridaceae). Commonly known as "sword lilies," the name derives from their long, blade-like leaves—gladius being the Latin word for "sword." These plants grow from underground storage organs called corms and feature tall, unbranched stems that bear vibrant, trumpet-shaped flowers arranged in a single-sided spike. Their striking appearance makes them highly valued both in gardens and as cut flowers.
Most gladiolus species are native to sub-Saharan Africa, particularly South Africa, though some are also found in Europe and Asia. The flowers come in a wide variety of colors, forms, and often display intricate patterns or ruffled edges. Each flower is bisexual and sits between green bracts, with its tepals forming a characteristic funnel-shaped corolla. Known for their bold inflorescences and extended vase life, gladiolus flowers are a popular choice in floral design and landscaping worldwide

Chrysanthemum (Chrysanthemum spp.), popularly known as “mum” or “guldaudi”, is a major commercial ornamental plant grown for cut flowers, loose flowers, and garden display. Belonging to the family Asteraceae, it is valued for its vibrant colors, diverse flower shapes, and long vase life. Chrysanthemum is attacked by several insect and mite pests, affecting both foliage and floral quality, leading to reduced aesthetic and commercial value.
Distribution: Widely distributed in India wherever chrysanthemum and sunflower are grown.
Biology: The eggs are laid singly on the upper surface of leaves, obliquely inserted into the tissue, with opercula appearing as whitish or brown dots. The incubation period for the eggs lasts about 5 to 7 weeks. Following hatching, the nymphs undergo hemimetabolous development (no true pupal stage). The nymphal period spans 2 to 3 weeks, during which the nymphs moult five times before reaching adulthood. Adult insects are approximately 4 mm long, with blackish bodies and lace-like transparent wings (Rizkawati et al., 2023).

Microbiology is the study of microorganisms or microbes. They are very small in size and hence cannot be seen with naked eyes. Microorganisms are excellent models for understanding cell function in higher organisms, including humans. Hence the science of microbiology is the foundation of all the biological sciences and microorganisms consist of bacteria, fungi, algae, protozoa and viruses. The fields according to the organisms studied are henceforth termed as:
Bacteriology - Bacteria (singular: bacterium)
Phycology (phyco, seaweed) - Algae (singular: alga)
Mycology (myco, a fungus) - Fungi (singular: fungus)
Protozoology (proto, first; zoo, animal) - Protozoa (singular: protozoan)
Virology - Viruses
Microbiology began when people learned to make lenses from glass and combine them to produce magnifications great enough to see microbes. The importance of bacteria in the lives of people, animals and the environment has been unfolded in the past 100 years. It was also believed that the incidence of the disease was due to divine reasons since man had no idea of microbes at this point of time. In the earlier days, leprosy was considered as a dangerous infectious disease and spread of the disease was attributed to direct contact with the affected persons. Hence, certain procedures were specified for
segregation of the affected persons. At this point of time various theories were also attributed to the genesis of disease. Some of the important theories are as follows:
1. Theurgical theory – Disease was attributed to the wrath of divine spirits as a punishment of individual sins.
2. Miasmatic theory – This theory was proposed by Hippocrates and further developed by his student Galen. It states that the disease was dueto the emanations from the

First discovered by Scottish surgeon sir Alexander ogston (1880) in infected tissues. He named it as staphylococcus” (Greek staphyle, bunch of grapes;
KOKKAS, berry).
Systematics
Domain : Bacteria
Phylum : Firmicutes
Class : Bacilli
Order : Bacillales
Family : Staphylococcaceae
Genus : Staphylococcus
Species : Staph. aureus
Staph. Intermedius
Staph. hyicus
Habitat and Ecology
Staphylococcus occurs worldwide in mammals although the spread of staphylococcal strains between different animal species is limited. They colonise the nasal cavity, skin and mucous membranes and can be transient in the intestinal tract. It is an opportunist type organism.

Actinobacillus species are non-motile, Gram-negative rods (0.3 to 0.5 x 0.6 to 1.4 μm) which occasionally have a coccobacillary appearance. They are non-motile, non-sporeformingand non-acid-fast. A surface slime is presentin the three major species (A. ligllieresii. A. equuli andA. suis) and may be related to the stickiness of theircolonies on agar. Surface cultures have low viabilityand die in 5-7 days. The actinobacilli ferment carbohydrates, without the production of gas, within 24 hours and most species produce urease and grow on MacConkey agar. Most species are urease and oxidase positive. The
reactions in the oxidase andcatalase tests are variable. The genus is still in a stateof flux, mainly because of the close similaritiesbetween actinobacilli and species in the genera Pasteurella and Haemophilus.
These facultative anaerobes ferment carbohydrates producing acid but not gas. Actinobacilli exhibit some host specificity and are mainly pathogens of farm animals.
Usual Habitat
Actinobacilli are commensals on mucous membranes of animals particularly in the upper respiratory tract and oral cavity. As actinobacilli cannot survive for long in the environment, carrier animals play a major role in transmission.
Colonial Appearance
• A. lignieresii: small, glistening colonies develop in 24 hours. They are usually slightly sticky (viscid) on primary isolation but lose th is characteristic on subculture. The colonies are non-haemolytic and develop to about 2 mm in diameter in 48 hours. The organism grows well on MacConkey agar, the colonies are at first pale but become pinkish as A. lignieresii is a late lactose-fermemer.
• A. equuli: some strains are haemolytic and the colonies are sticky with this feature remaining on subculture. I t is a lactose-fermenter onMacConkey agar.

Introduction
The genus Haemophilus contains small, nonmotile, nonsporing, oxidase positive, pleomorphic, gram negative bacilli that are parasitic on human beings or animals. Haemophilus means blood loving organisms.

Haemophilus species are small (less than 1 pm x 1 to 3 μm), Gram-negative rods, which often appear coccobacillary and may occasionally form short filaments. These motile organisms, which are facultative anaerobes with variable reactions in catalase and oxidase tests, do not grow on MacConkey agar. They are fastidious bacteria requiring one or both of the growth factors X (haemin) and V (nicotinamide adenine dinucleotide, NAD). Optimal growth occurs in an atmosphere of 5-10% CO2 on chocolate agar which supplies both X and V factors. Small, transparent, dewdrop-like colonies are formed by most Haemophilus species after incubation for 48 hours.

Colonies of H.somnus have a yellowish hue and some isolates are haemolytic on sheep blood agar. The main pathogens in the genus are H.somnus in cattle and sheep, H.parasuis in pigs and H.paragallinarum which is responsible for infectious coryza of chickens.

The haemophili are motile, facultative anaerobes, produce acid from glucose, reduce nitrates and are variable in the oxidase and catalase tests. They are nutritionally fastidious, will not grow on MacConkey agar and grow best on chocolate agar (supplying the X and V factors) under 5- 10 per cent CO2 at 37°C.

The growth of many of the Haemaphilus species is enhanced by 10 per cent CO2, As this is not inhibitory for any of them, CO2 should be used for routine isolation.The inoculated chocolate agar plates are incubated under 10 per cent CO2 at 35-37°C for 3-4 days, although some growth may be seen after 24 hours.

Introduction
Vibrios are Gram-negative, rigid, curved rods that are actively motile by means of a polar flagellum. The name ‘Vibrio’ is derived from the characteristic vibratory motility (from vibrare, meaning to vibrate). They are asporogenous and noncapsulated. Vibrios are present in marine environments and surface waters worldwide. The most important member of the genus is Vibrio cholerae, the causative agent of cholera. It was first isolated by Koch (1883) from cholera patients in Egypt, though it has been observed earlier by Pacini (1884) and others.
Natural Habitat
Vibrio spp. can be present in both freshwater and seawater as well as in the alimentary tracts of animals and man. At least five Vibrio spp. are human pathogens including V. cholerae, the cholera bacillus, and V.parahaemolyticus which causes food poisoning. Only V. metschnikovii is associated with disease in domestic animals. It causes a cholera-like disease in chickens and other birds but its geographical distribution is very limited. V. anguillarum causes infections in many species of fish especially in salt or brackish water. It causes high mortality in salt water eels.
Vibrio Cholerae
Morphology
The cholera vibrio is a short, curved, cylindrical rod, about 1.5 × 0.2-0.4 mm in size, with rounded or slightly pointed ends. The cell is typically comma shaped (hence the old name V comma) but the curvature is often lost on subculture. S-shaped or spiral form may be seen due to two or more cells lying end to end. Pleomorphism is frequent in old cultures. In stained films of mucus flakes from acute cholera cases, the vibrios are seen arranged in parallel rows,

Bacteroides spp are non-spore forming gram-negative bacilli that are part of the human resident flora. Microbiologically, they are distinguished from other genera by growth in 20% bile. At present, the Bacteroides fragilis group consists of ten species: B. fragilis (the most frequent isolate), B. distasonis, B. thetaiotaomicron, B. vulgatus, B. ovatus, B. eggerrthii, B. merdae, B. stercoris, B. uniformis, and B. caccae. Since 1990, many organisms previously designated as Bacteroides have been reclassified (see chapter on Anaerobes other than Bacteroides). Bacteroides, the predominant genus in the human
intestine, are important in numerous metabolic activities and may provide some level of protection from invasive pathogens. All 10 species are usually isolated from the colon, although infections caused by or associated with them can include virtually any organ.
Characteristics
The gram-negative Bacteroides spp. or closely related genera are capsulated obligatory anaerobic bacilli that are non-spore forming, pale-staining, and some are motile by peritrichous flagella, while other taxa are non-motile. Bacteroides, Parabacteroides, Odoribacter are generally bile resistant, distinguished from genera which are bile sensitive. They are normally commensal, found in the
intestinal tract of humans (mouth, colon, urogenital tract) and other animals. Many cultures of Bacteroides strains display brown to black pigmentation on blood agar media caused by esculin hydrolysis.
Morphology
In general, all strains were stained poorly with safranin, but well with dilute carbolfuchsin. Motility was not observed in any strains. The morphology of Bacteroides fragilis in fresh cultures and in pus is not
especially characteristic. In this form, the bacillus measures 0.5 by 2.0 to 2.5 micra. Older cultures tend to develop larger forms (0.6 to 0.8 by 2.0 to 9.0 micra) but even in this state the organism cannot be distinguished from aerobic Gram-negative bacilli, by its morphology.

The mycoplasmas are microorganisms in the class Mollicutes. Of the nine genera in this class, five contain species of veterinary interest. The genus Mycoplasma, in which there are about 100 species, contains most of the animal pathogens. The first mycoplasma identified in 1890 was Mycoplasma mycoides subspecies mycoides, the cause of contagious bovine pleuropneumonia. Similar types of mycoplasmas which were subsequently identified were called pleuropneumonia- like organisms (PPLO).
Mycoplasmas, the smallest prokaryotic cells capable of self-replication, are pleomorphic organisms ranging from spherical (0.3 to 0.9 pm in diameter) to filamentous (up to 1.0 μm long). Because they cannot synthesize peptidoglycan or its precursors, they do not possess rigid cell walls but have flexible, triplelayged outer membranes.
Their flexibility allows them to pass through bacterial membrane filters of pore size 0.22 to 0.45 μm. Mycoplasmas are susceptible to desiccation, heat, detergents and disinfectants. However, they are resistant to antibiotics such as penicillin which interfere with the synthesis of bacterial cell walls. Based on 5s rRNA sequence analyses, the mycoplasmas have been shown to be linked phylogenetically to Gram-positive bacteria such as Clostridium species which have low guanine-cytosine content in their DNA. They require enriched media for growth, characteristically forming umbonate micro-colonies
when illuminated obliquely and microcolonies with a ‘fried egg’ dppearance in transmitted light. The dense central zone is due to extension of the microcolony into the agar. Mycoplasmas, which have relatively small genomes (approximately 800 genes) are fastidious in their growth requirements.
Most mycoplasmas are facultative anaerobes and some grow optimally in an atmosphere of 5 to 10% CO2. Nonpathogenic anaerobic mycoplasmas are found in the rumens of sheep and cattle. The genera Mycoplasma and Ureaplasma contain animal pathogens.

Introduction
Q fever is a zoonotic bacterial infection caused by Coxiella burnetii, an obligate intracellular parasite, classified within the family Rickettsiaccae. Q fever (Q for “query”) was first used in 1937 to describe a mysterious febrile illness of packing house workers in Brisbane, Australia. The causative agent was isolated from infected workers and later was identified as Rickettsiae. Almost simultaneously the same organism was identified wood tick collected in Montana. Cox, an American, and Burnet, an Australian, where honored for their early work with this organism, hence the name “Coxiella burnetii”.
Host and Susceptibility
Coxiella burnetii is a well-established infectious agent that has reached a state of balanced pathogenicity in a plethora of host. Human are unnatural and usually dead-end-host. The microorganism generally maintained in a less pathogenic form in separate cycle existing independently among wild mammals and their haematophagus arthropods, principally tick and in domestic animals.
Morphology
It is an intracellular organism which is a polymorphic bacillus (0.2-0.4mm width, 0.4-1.0 mm length), which has a cell membrane, like Gram negative bacteria. However, it stains poorly with pigmented Gram stain, but gimenez staining is traditionally used to stain the Coxiella burnetii pathogen from pathological materials and crop. Coxiella burnetii has several distinctive characteristics, including a sporulationlike
process that protects the organism against the external environment, where it can survive for long periods. In mammals, the usual host cell of C. burnetii is the macrophage, which is unable to kill the bacterium. The other an important characteristic of C. burnetii is its antigenic variations, those called phase variation. This antigenic shift can be measured and is valuable for differentiating acute from chronic Q fever. Thus, it displays two antigenic phases those are phase-I and phase- II that are liable to the Lipopolysaccharide (LPS) of the membrane.

Bacteria from the genus Anaplasma belong to the Procaryota kingdom, the family Anaplasmataceae. Anaplasma belong to obligate intracellular microorganisms, Gram-negative bacteria, living in the blood cells of mammals. Vertebrates can be their reservoir, i.e. an environment where the pathogen can live and proliferate for many years. However, in many cases bacteria from the genus Anaplasma cause diseases in domestic animals and people.
Taxonomical Position of Bacteria from the Genus Anaplasma
The genera Anaplasma, Ehrlichia, Neorickettsia and Wolbachia include obligate intracellular bacteria, parasitizing in the vacuoles of cells in eukarytic hosts. Animal pathogens were attributed to the genus Anaplasma, such as A. centrale, A. marginale, A. platys, A. ovis and A. bovis, and also the aetiological factor of human anaplasmosis, A. phagocytophilum.
Anaplasma marginale
A. marginale are obligate intracellular bacteria parasitizing in erythrocytes of higher vertebrates, mostly ruminants.
Anaplasma Centrale
A. centrale is a parasite in the erythrocytes of ruminants, mainly cattle. As opposed to A. marginale, it creates concentrations in the central part of the cell. A. centrale is less pathogenic to cattle than A. marginale but, most importantly, occasionally gives resistance against the latter. Hence it is used for the preparation of live vaccine strains, assuring immunological protection against bovine anaplasmosis.
Anaplasma Bovis
A. bovis is a bacterium detected mainly in cattle, but also observed in small mammals which are probably a reservoir of this bacterium. It occurs in monocytes, and the disease it causes is called monocytic anaplasmosis. The symptoms of the disease are most visible in calves, but also in adult animals; symptoms include weakening of the body, marked reduction in weight, elevated temperature, enlargement of prescapular lymph nodes, paling of the mucous membranes, and in many cases an elevated amount of secreted mucus.

Organisms in the order Rickettsiales form a diverse group of small (0.3 to 0.5 x 0.8 to 2.0 pm), non-motile, pleomorphic Gram-negative bacteria which replicate only in host cells. They can be cultured in the yolk sac of embryonated eggs or in selected tissue culture cell lines. Because they stain poorly with aniline dyes, these organisms should be stained by Romanowsky methods such as Giemsa or Leishman. In addition to host-cell dependence and poor affinity for basic dyes, a requirement for an invertebrate vector distinguishes them from conventional bacteria and the Chlamydiales.
Epidemiology
Animal hosts and arthropod vectors are the reservoirs for most rickettsiae. A number of rickettsia1 organisms, including Ehrlichia canis, Anaplasma marginale and Haemobartonella felis produce latent infections. In arthropods, rickettsiae replicate in the epithelial cells of the gut before spreading to other organs, including the salivary glands and ovaries where further replication may occur.
Organisms are transmitted when the arthropod feeds on the animal host. Some organisms such as Rickettsia rickettsii are maintained in a tick population by transovarial transmission. Trans-stadial but not transovarial transmission of E. canis and E. phagocytophila occurs in ticks. With the exception of Coxiella burnetii, which produces endospore-like forms and can remain viable in dust for up to 50 days, most rickettsiae are labile outside host cells. Aerosol transmission of C.burnetii commonly occurs in domestic animals and humans. In addition, a silent cycle involving ticks and small wild mammals may constitute a possible source of infection for some domestic species.
Pathogenesis and Pathogenicity
Many Rickettsia species including the causal agents of typhus (R. prowuzekii), murine typhus (R. typhi) and scrub typhus (R. tsutsugamushi) are primarily human pathogens. Rocky Mountain spotted fever, caused by Rickettsia rickettsii, which is a common rickettsia1 disease of humans, also affects dogs.

Chlamydiae are obligate intracellular bacteria with an unusual developmental cycle during which unique infectious forms are produced. They replicate within cytoplasmic vacuoles in host cells. On account of their apparent inability to generate ATP, with resultant dependence on host cell metabolism, they have been termed ‘energy parasites’.
The family Chlamydiaceae belongs to the order Chlamydiales. Currently two genera, Chlamydia and Chlamydophila, and nine species are described. Formerly a single genus and four species, Chlamydia trachomatis, C. psittaci, C. pneumoniae and C. pecorum, were recognised. This classification was based on phenotypic characteristics such as host preference, inclusion morphology, iodine staining for the presence of glycogen, and sulphonamide susceptibility. However, recent nucleic acid sequencing studies of the 16s and 23s rRNA genes confirm two distinct lineages.
In the developmental cycle of chlamydiae, infectious and reproductive forms are morphologically distinct. Infectious extracellular forms, called elementary bodies (EBs) are small (200 to 300 nm), metabolically inert and osmotically stable. Each EB is surrounded by a conventional bacterial cytoplasmic membrane, a periplasmic space and an outer envelope containing lipopolysaccharide.
The periplasmic space does not contain a detectable peptidoglycan layer and the EB relies on disulphide cross-linked envelope proteins for osmotic stability. Elementary bodies enter host cells by receptor-mediated endocytosis. Acidification of the endosome and fusion with lysosomes are prevented by mechanisms which are not fully understood. A process of structural reorganization within the pathogen, of several hours duration, results in the conversion of an EB into a reticulate body (RB). The RB, about 1 μm in diameter, is metabolically active, osmotically fragile and replicates by binary fission within the endosome. The endosome and its contents, when stained, is called an inclusion. When a number of inclusions containing RBs of C.trachomatis are formed in an infected cell, fusion of these structures may
occur.

The Government of India, during 1980s, recognized the necessity to improve the latex yield productivity in the traditional rubber growing regions and also expand these plantations to non-traditional regions to meet the ever increasing demands of natural rubber in India (Sethuraj et al., 1989). Agrometeorological studies were initiated during early 1986 with the appointment of a Scientist (Agrometeorology). To begin with, scientific issues were identified as: (a) delineate the potential non-traditional regions for expansion of rubberplantations, (b) estimate the impact of climatic conditions, especially abiotic  stress conditions on productivity, (c) quantify influence of meteorological factors on the physiological responses towards plant growth and yield attributes, (d) estimate the irrigation requirements to mitigate the drought conditions, and (e) develop weather based predictive models for `Abnormal leaf fall’ disease of rubber plantations. An attempt is made to present synthesis of accomplishments during 1986 to 1992 period of my association with the Rubber Research Institute of India (RRII), Kottayam.

Introduction
In the era of digital media consumption, smartphones have emerged as powerful tools for video creation and editing making it accessible to everyone, from casual users to professional creators. With advancements in mobile technology, users can capture high-quality video and audio and edit them seamlessly within mobile applications. However, one of the significant challenges in video production is achieving proper synchronization between audio and video tracks. This chapter explores the principles of audio synchronization, the importance of this process in video editing, and practical techniques for
achieving perfect alignment using smartphone applications.
Understanding Audio Synchronization in Mobile Video Editing
Audio synchronization, or “lip-syncing,” is particularly vital in videos where
dialogue, music, or sound effects are synchronized with visual cues. Accurate synchronization can help convey emotions, emphasize actions, and create an immersive experience. On smartphones, achieving perfect synchronization requires both intuitive tools and practical techniques to account for various factors, such as audio drift, frame rates, and video quality.
Smartphone applications for video editing typically support audio synchronization through visual audio waveform displays, alignment tools, and timing adjustments. These features empower users to manually or automatically adjust and align audio with visual footage.

Introduction
Video and audio editing encompass two primary modes: online and offline editing, each critical for producing high-quality, synchronized media content. Online editing refers to real-time editing with high-resolution files, typically as a final step in the post-production workflow. Offline editing involves working with lower-resolution copies or proxies of footage for easier manipulation and organization, saving time and computational resources. Both techniques hold unique advantages and can be integrated depending on project requirements, available resources, and editing goals.
Section 1: Understanding Offline Editing
1.1 Overview of Offline Editing
Offline editing is the preliminary editing stage where editors work with lower-resolution copies of the original footage to perform initial edits. This approach optimizes efficiency, as low-resolution files consume less storage and processing power. Common in projects with extensive footage, such as feature films, documentaries, and complex multimedia presentations, offline editing allows editors to focus on the structure, sequencing, and timing of content without concerns over resource demands.

As video editing continues to evolve, so do the techniques and software that enable editors to create polished, captivating visuals. Advanced editing techniques like precision cutting, mixing, and using sophisticated software tools allow editors to enhance storytelling, manipulate pace, and shape the emotional experience of their audience. This chapter dives into these advanced techniques, exploring how each tool and method contributes to a compelling final product.
1. The Art of Cutting: Techniques for Seamless Storytelling
Cutting is a fundamental editing skill that determines the pacing, continuity, and flow of a video. Advanced cutting techniques, such as L-cuts, J-cuts, and match cuts, serve as the foundation for creating dynamic narratives.
• Types of Cuts
• L-Cut and J-Cut: L-cuts and J-cuts are used to transition between audio and video in ways that flow more naturally and create smoother  continuity between scenes. These are essential techniques for dialogue-driven scenes or scenes that require seamless transitions between different locations or times.

Abstract
Aquatic weeds, such as duckweed, present a dual challenge and opportunity within aquatic ecosystems and the poultry feed industry. These fast-growing plants, often deemed nuisances due to their potential to disrupt ecosystems, offer significant potential as alternative feed sources. Duckweed, a floating aquatic plant, is particularly noteworthy due to its high protein content, rapid growth rate, and nutrient recycling capabilities. In freshwater systems, excessive growth of aquatic weeds can lead to decreased ecosystem productivity, hypoxia, and anoxia, making effective management crucial. However, duckweed’s ability to thrive in nutrient-rich conditions and its high nutritional value, including substantial protein and essential vitamins, position it as a valuable feed ingredient for poultry. The Indian poultry sector, growing at an annual rate of 8-10%, faces challenges such as rising feed costs and limited availability of conventional feed ingredients. Integrating duckweed into poultry diets can provide a cost-effective, sustainable alternative that reduces reliance on traditional feed sources and supports ecosystem management. This approach not only addresses feed shortages but also contributes to environmental sustainability by recycling nutrients and mitigating pollution. Despite its potential, challenges such as lack of standardized regulations and market acceptance remain. Continued research, policy support, and market promotion are essential to harness the full benefits of aquatic weeds.

Introduction
Plants have been used for ages as animal and human health cures. Ethnoveterinary medicines, a phrase that primarily refers to folk skills, beliefs, knowledge, practices, and procedures related to animal health and the treatment of various disorders in rural regions, have acknowledged the ability of plants to combat a variety of diseases. The World Health Organisation (WHO) defines traditional medicine, also referred to as herbal medicine, as “When it comes to maintaining health and preventing, diagnosing, improving, or treating physical and mental illnesses, the entirety of the knowledge, abilities, and practices derived from indigenous theories, beliefs, and experiences whether or not they can be explained as illness”. Approximately 25% of contemporary medications are derived from plants that were once used in traditional medicine. The use of traditional medicine and its confirmation could result in the creation and discovery of more novel medications.

Introduction
Helminths are a group of internal parasites of animals and human beings that usually infest gastrointestinal tract that feed from the host which provides protection to the parasite. The infestation cause loss of blood and nutrients from the host, making it weak, and vulnerable to other infections. There can be injury to other organs due to the migration of different stages of the parasite, formation of cysts or secretion of toxins that can cause damage.
The heminths belong to two phyla including nemathelminthes which are round worms and Platyhelminthes that has flukes, and tapeworms. Nematodes are round worms who have a resistant cuticle and most of them have separate sexes with direct or indirect life cycle. The major nematodes include Ascarids, Strongyles, strongyloides, Trichostrongyles, Filarids, Trichuris etc. Tape worms have a flat body with a head or scolex, neck and strobili having proglottids. They are hermaphrodites and the proglottids contain reproductive organs. They require more than one host for completion of life cycle. The flukes are ususally leaf like , unsegmented and have suckers that help them to attach to the internal organs of the host. They also have a life cycle in more than one host.

The kidney plays a role in controlling the volume of different bodily fluids, fluid osmolality, acid-base balance, toxin elimination, and different electrolyte concentrations. The glomerulus filters one-fifth of the volume of blood that enters the kidneys. Among the compounds that are reabsorbed include amino acids, salt, bicarbonate, glucose, and solute-free water. Among the chemicals that are released are ammonium, potassium, hydrogen, and uric acid. The kidneys maintain homeostasis, eliminate metabolic waste products like uric acid, urea, creatinine and ammonia, regulate extracellular fluid volume, blood pressure (via the rennin-angiotensin system) and controlling systemic pH (via regulation of H+ and HCO3- concentration).
Among various kidney diseases, especially chronic kidney disease (CKD) is a slow loss of kidney function in which, kidney dysfunction is present for more than three months. There are six progressive stages of CKD i.e. stages 1, 2, 3a, 3b, 4 and 5. The stages are based on the results of glomerular filtration rate (GFR) test (1). In stage 1 there is mild kidney damage, while in stage 5 kidneys lost their working capacity. Chronic kidney disease (CKD) is a worldwide health issue that is becoming more prevalent in both developed and developing nations. It typically affects adults. .

Nervous system Disorders in Domestic Animals
Nervous system disorders in domestic animals encompass a range of conditions that affect the brain, peripheral nerves, and spinal cord. These disorders can result in a variety of clinical signs, depending on the area of the nervous system involved. Infectious disorders like rabies, canine distemper, toxoplasmosis, listeriosis. Congenital and developmental disorders like hydrocephalus, cerebellar hypoplasia and chiari-like malformation can cause these disorders. Traumatic and degenerative disorders like Intervertebral Disc Disease. Degenerative myelopathy, metabolic and toxic disorders like hepatic encephalopathy, hypocalcemia, lead poisoning, organophosphate toxicity, autoimmune and inflammatory disorders like meningitis and meningoencephalitis may also lead to nervous system disorders. Some tumours associated with nervous system like meningiomas and peripheral nerve sheathtumours also cause nervous system disorders.  

Abstract
Aquaculture is the fastest-growing food production sector globally, with finfish and crustaceans playing a significant role in meeting the growing demand for animal protein. However, aquaculture’s reliance on marine capture fisheries for essential feed ingredients, such as fishmeal and fish oil, presents significant sustainability challenges. The Fish In: Fish Out (FIFO) ratio, which estimates the quantity of wild-caught fish used to generate one unit of reared fish, has become a key metric in assessing the sustainability of aquaculture. A high FIFO ratio indicates greater dependence on wild fish stocks, contributing to overfishing and ecosystem degradation. This chapter explores the FIFO ratio, its role in promoting sustainable aquaculture, and innovations to reduce its environmental impact. Over the years, the global average FIFO ratio has improved, reflecting advances in feed efficiency and the incorporation of alternative ingredients such as plant-based proteins, insect meals, and by-products from fish processing. However, challenges remain in these alternatives’ availability, cost, and nutritional performance. Case studies, including salmon rearing in Scotland and shrimp farming in Thailand, demonstrate the potential of alternative feed ingredients in lowering FIFO ratios and enhancing sustainability. This chapter also addresses the limitations of the FIFO ratio as a singular sustainability metric, calling for a more holistic approach to evaluating aquaculture’s environmental and economic impacts. Ultimately, achieving sustainable FIFO ratios will require
continued innovation, improved feed formulations, and global collaboration to ensure aquaculture’s role in providing a sustainable source of protein for the growing global population.
