Family: Chenopodiaceae

Flowering: November-January Fruiting: February-April

Botanical description: The plant is a fast-growing, upright and weedy annual herb. The leaves are variables in appearance. The first leaves, near the base of the plant, are toothed and 3-7 cm long and 3-6 cm broad. The leaves on the upper part of the flowering stems are entire and lanceolate-rhomboid with 1-5 cm long and 0.4-2 cm broad. The flowers of the plant are 1-1.2 mm across, in short axillary spikes and often forming a terminal thyrse. Seeds are black, depressed with an obscure horizontal keel.

The word ‘chlamydia’ comes from the Greek word ‘chlamys’ means ‘cloak draped around the shoulder’. It describes how the intracytoplasmic inclusions produced by the bacterium appear under the microscope(‘draped’ around the host cell nucleus). Chlamydia was first discovered by a Czech zoologist and parasitologist, Stanislaus von Prowazek in 1907 in Berlin. Originally because of its structure it was thought to be a virus. In 1963 it was recognized as a bacterium rather than a virus.

Properties of genus

1. Morphology: Chlamydia are Gram-negative, non-motile, pleomorphic and obligate intracellular bacteria. The Gram-negative cell wall consists of cytoplasmic and outer membrane. However, they lack peptidoglycan layer. Moreover, they also encode major outer membrane protein (MOMP), the key antigenic determinant used for serological differentiation of chlamydiae.

They are poorly stained by Gram’s stain. Chlamydiae are readily stained by Castaneda (blue in appearance), Giemnez and Macchiavello (red in appearance) methods. However, Giemsa staining is preferable to stain the inclusions (chlamydial micro colony) in the cell culture. Inclusion bodies of the Chlamydiae are basophilic in nature. The staining of the inclusion bodies may differ depending on the species. In C. trachomatis, the inclusion bodies contain glycogen matrix and can be easily stained with iodine solution.

5. Description

Nepalese Hog plum is a evergreen tree that can grow up to 10 metres tall, though is usually smaller. The bole is buttressed and about 30 - 40cm in diameter. The plant is especially valued for its edible fruit and is being increasingly cultivated for this purpose, the fruit being used locally and traded internationally. It is also used as a pioneer fruit tree in reforestation projects. Currently products of Lapsi fruit are mostly consumed locally. Lapsi fruit tree possess immense potential for income generation for hill farming communities. In Nepal, the tree is known for its delicious fruit. The Lapsi fruit tree which produces pistillate flowers are locally called as “pothi lapsi” which is a female tree and the other which produces staminate flowers is known as bhale lapsi which is a male tree. In Vietnam it is known for medicinal importance and in China for timber usage.

Cleome gynandra is one of the most underutilised crops in the world. It is the best known by rural and urban communities of Africa. The plant is well distributed in parts of South Africa, C. gynandra is indigenous to the country and evenly spread throughout Africa. Many people use it in their daily diets but it is not yet found on formal commercial markets. It is still regarded as a weed by commercial farmers. The nutritional value of the leaves is totally underestimated. The plant is known for the treatment of various ailments originated from epilepsy to headaches. The crop is harvested mainly from the wild and only cultivated in certain areas. The germination of the seeds can be a problem especially if the seeds are harvested simultaneously. The seeds must be harvested as it gets matured not all at once. Most consumers harvest the plant as needed. The more the leaves are picked the more growth is stimulated. A general harvesting method is not worked out yet, as this will differ from area to area.

Corynebacterium diptheriae was first observed by Klebs in 1883 and was described in details by Loeffler in 1884. So it is also known as ‘Klebs- Loeffler bacillus’. In 1888, Nocard isolated a similar type of bacteria from cases of bovine farcy. In 1894, Preisz described it completely and revealed its similarities with the diphtheria bacilli. Later it was named as Corynebacterium pseudotuberculosis (Preisz-Nocard bacillus). Bollinger (1890) first reported C. renale from the cases of pyelonephritis in cows.

The genus Trueperella was proposed by Yassin and others (2011) to describe T. pyogenes previously known as Arcanobacterium pyogenes or Actinomyces pyogenes or Corynebacterium pyogenes. The genus Arcanobacterium was first described (Collins and others, 1982) to include the bacteria originally isolated as Corynebacterium haemolyticum from the wounds of American soldiers. On the basis of 16S rRNA comparisons and menaquinone and phospholipid compositions it is proposed that the species Arcanobacterium pyogenes should be reclassified as members of the new genus Trueperella.

The genus Rhodococcus was first introduced by Zopf (1891) as a soil bacterium used in horticulture. Magnusson (1923) described C. equi (Rhodococcus equi) from suppurative pneumonia of a foal.

Family : Dioscoreaceae

Flowering & Fruiting: September-October

Botanical description: Aerial yam is a glabrous-leafed, non-spiny, perennial climbing plant producing annual stems up to 10 metres long from a woody, tuberous rootstock. These stems scramble over the ground, or twine into the surrounding vegetation. The stems twine left-handed and produce aerial axillary bulbils. The plant produces tubers; however the bulbils which grow at the base of its leaves are more important food products. They are about the size of potatoes (hence the name air potato) weighing from 0.5 to 2 kg. The flowers are whitish or pinkish in colour.
