This work aims to identify 6 virus field isolates, serologically determined as reoviruses. The type of cytopathic effect in cell cultures, physico-chemical properties and antigenic relationship were examined. The strains examined multiplied in CEF and CEK cultures, produced cytopathic effects and plaques, contained RNA in their genome, had no lipid envelope, were stable in an acid environment and belonged to the same serotype but two different subtypes.
