title: [2 strains of swine parvoviruses isolated from aborted fetuses].
abstract: Two hemagglutinating virus strains were isolated (in primary cell cultures of pig kidneys) from viscera of aborted swine fetuses. A number of serologic, cytologic, physico-chemical, and laboratory investigations with the strains revealed that they belonged to the group of porcine parvovirus (PPV). The isolation of SPV from aborted fetuses pointed to the fact that the disease had been widespread among the swine population and plays a part in reproduction disturbances that have come to be known recently. The isolated strains did not produce a clear and distinguishable cytopathic effect in inoculated cell cultures. They, however, could be demonstrated in the cultures indirectly through cytologic investigation (the demonstration of intranuclear inclusion bodies, type B after Cowdry, through hemagglutination tests, and via immunofluorescent microscopy.
