Abstract

Treatment of a cell line derived from the Asian feral mouse Mus caroli with 5-bromodeoxyuridine induces an infectious, xentropic type C virus. This virus shares strongly cross-reactive reverse transcriptase (RNA-dependent DNA polymerase) and p30 antigens and crossinterferes with type C viruses isolated from a woolly monkey (SSAV) and gibbon apes (GALV). By similar criteria, the caroli virus is much less related to previously described type C viruses of the laboratory mouse, Mus musculus. Induction of virus from 10 of 13 single cell clones indicates that the virus is endogenous in Mus caroli cells. Thre results suggest that infectious primate type C viruses arose by trans-species infection(s) of certain primates with endogenous type C viruses from MUs caroli or a closely related Mus species.

摘要

用5-溴脱氧尿苷处理源自亚洲野生小鼠(小家鼠)的细胞系可诱导产生一种具有传染性的、嗜异种性C型病毒。这种病毒具有强交叉反应性的逆转录酶(RNA依赖性DNA聚合酶)和p30抗原,并与从绒毛猴(SSAV)和长臂猿(GALV)分离出的C型病毒发生交叉干扰。根据类似标准,小家鼠病毒与先前描述的实验小鼠(小家鼠)的C型病毒关系要小得多。从13个单细胞克隆中的10个诱导出病毒,表明该病毒在小家鼠细胞中是内源性的。这些结果表明,传染性灵长类C型病毒是由某些灵长类动物被源自小家鼠或密切相关小家鼠物种的内源性C型病毒进行跨物种感染而产生的。
