Pathogenicity for chickens of a reovirus isolated from turkeys.

A viral agent that was isolated from livers of commercial turkey poults that died at approximately two weeks of age was characterized as a reovirus. Experimental infection of day-old chickens with this reovirus isolate resulted in the development of tenosynovitis, hepatitis, and myocarditis. In vitro neutralization of the turkey reovirus isolate by antiserum against chicken reovirus correlated with in vivo protection of maternally immune chickens from day-old oral challenge with the turkey reovirus isolate.
