Paratuberculosis, also referred to as Johne's disease, affects principally cattle, goats, sheep, buffalo, deer and other ruminants. It is common worldwide and responsible for significant economic losses in the ruminant livestock industries. A timely follow up to the first book on Paratuberculosis, this new edition is still the only comprehensive text providing both historical context and the latest developments in the field. Examining the epidemiology of paratuberculosis, the organism that causes the disease, and practical aspects of its diagnosis and control, it also addresses the link between paratuberculosis in the food chain and human health implications, including Crohn's disease. This new edition: * Builds on a strong foundation to update, streamline and better structure existing chapters with important new developments from the last decade, such as whole genome sequencing and phage-based assays; * Includes new chapters on the fast-growing field of whole genome based comparative genomics, and the increasing opportunities for disease control in low- and middle-income countries; * Increases inclusivity by bringing on board new rising star authors from diverse backgrounds to provide international perspectives. A truly comprehensive, critical reference resource, this book is an essential reference for large animal veterinarians, livestock industry personnel and those involved in the dairy and meat industries, as well as microbiologists, researchers and students in these fields.
