Abstract

Simian foamy viruses (SFV) are ancient retroviruses of primates and have coevolved with their host species for as many as 30 million years. Although humans are not naturally infected with foamy virus, infection is occasionally acquired through interspecies transmission from nonhuman primates. We show that interspecies transmissions occur in a natural hunter-prey system, i.e., between wild chimpanzees and colobus monkeys, both of which harbor their own species-specific strains of SFV. Chimpanzees infected with chimpanzee SFV strains were shown to be coinfected with SFV from colobus monkeys, indicating that apes are susceptible to SFV superinfection, including highly divergent strains from other primate species.

摘要

猿猴泡沫病毒(SFV)是灵长类动物的古老逆转录病毒,与它们的宿主物种共同进化了多达3000万年。虽然人类不会自然感染泡沫病毒,但偶尔会通过从非人类灵长类动物的种间传播而获得感染。我们发现种间传播发生在一个自然的捕食系统中,即在野生黑猩猩和疣猴之间,这两种动物都携带着它们各自物种特异性的SFV毒株。感染了黑猩猩SFV毒株的黑猩猩被证明同时感染了来自疣猴的SFV,这表明猿类易受SFV重复感染,包括来自其他灵长类物种的高度分化的毒株。
