Interpretive Summary: Avian reoviruses (ARV) are widespread worldwide and may infect turkeys, chickens and other avian species, including domestic waterfowl and game birds. The virus is non-enveloped double-stranded RNA, therefore is environmentally stable and due to its segmented genome can generate variants easily. Antigenic subgroups have been described, but cross reactions among groups are not uncommon. The pathogenesis of ARV infection can vary depending on the host species and characteristics of the ARV strain involved. Many reoviruses do not cause clinical disease. In some cases it is believed that ARV’s may not act as primary pathogens, but are opportunistic and clinical disease only occurs from some synergistic effect between ARV and another infectious agent. This book chapter describes the essential clinical and diagnostic features of avian reoviruses in poultry.
