title: Antigenic heterogeneity of avian paramyxoviruses of serotype 2 ("Yucaipa-like") isolated from domestic and wild birds in Israel.
abstract: Thirty-three viruses of PMV-2 serotype isolated in Israel from domestic and wild birds during epizooty of a respiratory disease in 1979-1981 were studied comprehensively in comparison with a set of reference PMV-2 viruses using cross reaction hemagglutination inhibition tests, elution-hemagglutination pattern and pattern of migration of viral proteins in polyacrylamide gel electrophoresis. The results demonstrated considerable heterogeneity amongst the local isolates by the above three criteria which were not correlated with each other. There was no significant correlation between the differences found and chronology of isolation of the viruses. The results indicated that there may have been simultaneous co-circulation of different PMV-2 strains in the local avian reservoir at the beginning of the epizootic rather than temporal accumulation of variants as a result of antigenic drift of an "ancestor" virus which caused the initial infection.
