Abstract
- Avian reoviruses are ubiquitous among poultry flocks. Although infection is usually present without disease, reoviruses may occasionally be involved in several disease syndromes of which viral arthritis/tenosynovitis in chickens is the most important, particularly in broiler breeds. While reoviruses have been isolated from turkeys and several other species of birds with various conditions, the presence of the virus has been conclusively linked with disease in relatively few instances. In chickens in particular, avian reoviruses with a wide spectrum of pathogenic capability have been isolated and several antigenic types exist. Diagnosis is dependent on the detection of the virus in clinical samples, although the presence of the virus does not necessarily confirm that this is the cause of the disease, except where reoviruses are detected in affected joints. Serological tests are usually difficult to interpret in view of widespread and frequently harmless reovirus infection. The principal approach to control of viral arthritis/tenosynovitis is by vaccination using attenuated vaccines in young birds, followed by inactivated preparations for breeders intended to protect chicks by maternal antibodies. Many vaccines are based on the S1133 strain isolated in the United States of America, but these may not be effective against antigenic variants.
