Veterinary virology is a branch of veterinary medicine that focuses on the study of viruses that affect animals. This field comprises various aspects, including virus detection, characterization, epidemiology, pathogenesis, prevention, and control. Veterinary virology plays a critical role in identifying emerging viral diseases in animals, such as avian influenza, foot-and-mouth disease, and porcine epidemic diarrhea, and in developing strategies to mitigate their impact. Advanced laboratory techniques like polymerase chain reaction (PCR), serological assays, and sequencing are utilised to diagnose viral infections accurately. Development of vaccines and antiviral treatments also fall under its scope to protect animals from viral diseases. It investigates the role of viruses in zoonotic transmission, where diseases can transmit from animals to humans. This book includes some of the vital pieces of work being conducted across the world, on various topics related to veterinary virology. It provides significant information of this discipline to help develop a good understanding of virology and veterinary sciences. For all those who are interested in veterinary sciences, this book can prove to be an essential guide.
