avian reoviruses (arvs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. in this study, the molecularcharacteristics of arvs in some broiler breeder flocks were investigated in...

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 ...

Orthoreoviruses have been associated with a variety of diseases in domesticated poultry and wild-living birds. In 2002, a reovirus strain named Tvärminne avian virus (TVAV), was identified in Finland in a crow showing neurological disorders. The objective of this study was the molecular characterization of this novel reovirus strain. Genome sequencing was performed by combining semiconductor se...

The cytopathic effect evidenced by cells infected with avian reovirus S1133 suggests that this virus may induce apoptosis in primary cultures of chicken embryo fibroblasts. In this report we present evidence that avian reovirus infection of cultured cells causes activation of the intracellular apoptotic program and that this activation takes place during an early stage of the viral life cycle. ...
