Two studies were performed in pregnant heifers to determine whether inoculation with two bovine viral diarrhoea viruses (BVDV), one BVDV-1 and one BVDV-2, inoculated separately into either nostril, results in fetal infection with both viruses. Dual transplacental infection of the fetus with BVDV-1 and BVDV-2 was observed in one case, but not consistently.
两项研究在怀孕的小母牛中进行，以确定分别接种到两个鼻孔的两种牛病毒性腹泻病毒（BVDV），一种 BVDV-1 和一种 BVDV-2，是否会导致胎儿同时感染两种病毒。在一种情况下观察到 BVDV-1 和 BVDV-2 对胎儿的双重胎盘感染，但并不一致。
