A new member of the papovavirus group has been isolated and appears to infect swine. The new agent, tentatively named swine papovavirus, appears to be very defective and replicates only within a very narrow host cell range. The original source of the isolate is under investigation. Preliminary evidence suggests that the origin of swine papovavirus is either a stable pig kidney cell line or pancreas-derived trypsin
乳头多瘤空泡病毒组的一个新成员已被分离出来，且似乎可感染猪。这种新病原体暂命名为猪乳头多瘤空泡病毒，似乎存在严重缺陷，仅在非常狭窄的宿主细胞范围内复制。该分离株的原始来源正在调查中。初步证据表明，猪乳头多瘤空泡病毒的起源要么是一种稳定的猪肾细胞系，要么是胰腺来源的胰蛋白酶。
