The Atlas of Transboundary Animal Diseases is intended to assist Veterinary Service field staffs involved in animal disease surveillance and diagnostics in identifying important transboundary diseases of livestock. The focus of The Atlas of Transboundary Animal Diseases is on key images of clinical signs and post mortem lesions associated with 29 OIE notifiable animal diseases supplemented by basic disease information from the OIE technical disease cards. Input for this consolidated reference volume comes from OIE's global network of veterinary epidemiologists and diagnostic experts and the support of APHIS-USDA.
