Avian reovirus

Avian reoviruses (ARV) are non-enveloped, double-stranded ribonucleic acid viruses. They have been found to be involved in several disease syndromes in chickens, which includes malabsorption/stunting syndrome, and viral arthritis (tenosynovitis). ARV have also been associated with pasty vent, ulcerative enteritis, inclusion body hepatitis and sudden deaths in young broiler chickens in Poland.

ARV viruses can survive for up to 10 days on feathers, wood shavings, glass, rubber and galvanized metal. In water, they can survive for up to 10 weeks. ARV can be transmitted both vertically and horizontally, however most chicks become infected at an early age by the oral-fecal or occasionally the respiratory route, from infected hatch mates, environment or contaminated eggs, brooder, or incubator.
