Serological characteristics of avian reoviruses of Australian origin

Abstract
The antigenic relationship of plaque purified avian reoviruses isolated from commercial chickens in Australia was determined with a serum neutralisation procedure using antisera prepared in rabbits. Ten selected isolates were assigned to three groups based upon relatedness values determined by cross‐neutralisation studies. Considerable cross‐reactivity was demonstrated against heterologous types and the three groups were considered to be subtypes rather than distinct serotypes.
