This book offers a timely and comprehensive review of essential research on Peste des Petits Ruminants Virus (PPRV), ranging from its historical distribution, molecular epidemiology, genome structure, viral proteins, immunity, viral pathogenesis, clinical and molecular diagnosis to advances in vaccine developments and future challenges. PPRV, a Rinderpest-like virus, is the causative agent of one of the most rapidly emerging viral diseases among domestic small ruminants, and the host spectrum has now been expanded to wild small ruminants and camels. With the global eradication of the first livestock disease, Rinderpest, attention is now turning to repeating the procedure for PPR. Each of the book 13 chapters is dedicated to a specific topic, providing up-to-date literature and discussions by renowned scientists who have made seminal contributions in their respective fields of expertise. Special emphasis has been placed on the analysis of different global efforts to eradicatePPR. This book offers a valuable reference source for virologists, field veterinarians, infection and molecular biologists, immunologists, scientists in related fields and veterinary school libraries.
