title: [Detection of PI-3 viruses, BVD-MD viruses and parvoviruses in bovine fetuses after experimental intrauterine infections].
abstract: Growing organ cultures prepared from foetuses experimentally infected in utero by the viruses PI-3 and BVD-MD or bovine parvovirus proved to be suitable in tests with the re-isolation of these viruses 7, 14, 21, 35, 42 and 70 days after infection. The attempts at demonstrating them by the traditional method of the inoculation of the primary cell culture of foetal kidneys were successful only at the re-isolation of the PI-3 virus seven days after infection. The PI-3 virus without cytopathic effect was demonstrated in the primary cell culture prepared from the spleen, lungs, kidneys and testes of foetuses delivered seven days from infection. The cytopathic effect manifested itself after cell transplantation in the first passage when further multiplication of the virus occurred.
