RESUMO

A viral agent was isolated from the fetal liver of an aborted equine fetus. The isolate hemagglutinated red blood cells from guinea pig, rhesus monkey and rooster. By hemagglutination inhibition tests, the isolate was shown to be antigenically distinct from parvoviruses of bovine and canine origin. Specific hemagglutination inhibiting antibody against the viral isolate was exhibited by 26 of 136 horse sera tested. The isolated virus showed properties compatible with those of an autonomous parvovirus including size, morphology, stability to ether treatment and heating to 56 degrees C, the presence of a 5300 base DNA genome, characteristic protein composition and density (1.405 g/mL). The virus was classified as an equine parvovirus.
