Abstract
Intranasal and oral exposure of two gilts to porcine parvovirus on either the seventh or 14th day of gestation resulted in prenatal infection. Normal appearing fetuses and necrotic remnants of what were believed embryos and extraembryonic membranes were found when the gilts were necropsied seven weeks after exposure. The presence of masses of porcine parvovirus antigen throughout necrotic tissues of six of seven embryos, but not in any of the nine normal appearing fetuses suggested that embryonic death was due to porcine parvovirus.
