Veterinary Science is an important branch devoted to caring for all species of animals. A galaxy of subjects just like human medicine is taught encompassing a large number of animals. Microbiology is an inherently valuable and useful discipline that offers an insight of an invisible world. There are a galaxy of infectious diseases of animal and human caused by a variety of microorganisms. Among them, viruses and bacteria are of paramount importance because of enormous economic losses due to high morbidity, high mortality, reduced productivity, impaired work ability, reproductive inefficiencies and disturbances of national and international trade. Micro-organisms are everywhere. They exist in a range of environments including in the air we breathe, in the food we eat and even within our own body. In fact we come in contact with countless numbers of micro-organisms every day. Although some microbes can cause disease, most are rather play a pivotal role in the processes that provide energy and make life possible. Some even prevent disease and others are used in an attempt to cure diseases. As microorganisms play diverse role in the world, microbiology continues to be an exciting and interesting discipline to study. The book ‘VETISCAN’ has been written to provide relevant and current informations on all the aspects of important viral and bacterial diseases of animals including immunology, famous scientist associated with discoveries, industrial microbiology, antibiotics, biochemistry, bacteriology, virology, genetic engineering, public health etc to the students, teachers, scientists, diagnosticians, researchers, policy makers etc. Further it will continue to be an important subject to study with lot of recent developments and areas to be explored.
