中文百科

猴免疫缺陷病毒 Simian immunodeficiency virus

(重定向自Simian acquired immunodeficiency syndrome)

猴免疫缺陷病毒英语:Simian immunodeficiency virus,简称SIV),也称为非洲绿猴病毒英语:African Green Monkey virus),是一种可影响至少33种非洲灵长目的逆转录病毒。在对比奥科岛(于大约11000年前因海平面上升而从大陆隔离出来的一座岛屿)的四种猴中所发现的病毒株进行分析后,科学家们得出结论,称SIV在猴和猿中至少已存在了32000年,且实际存在时间可能比这长得多。

这些灵长目动物中的两个物种中存在的病毒株,即白顶白眉猴体内的SIVsmm和黑猩猩体内的SIVcpz,被认为已跨越了种间屏障而进入人体,并最终成为了HIV的两个亚型,即HIV-2和HIV-1。HIV-1转移到人体最可能的路径之一是人类与黑猩猩(在非洲常作为“丛林肉”的来源而被捕猎)血液的接触。

Description de cette image, également commentée ci-après

Simian immunodeficiency viruses (SIVs) are retroviruses able to infect at least 45 species of African non-human primates. Based on analysis of strains found in four species of monkeys from Bioko Island, which was isolated from the mainland by rising sea levels about 11,000 years ago, it has been concluded that SIV has been present in monkeys and apes for at least 32,000 years, and probably much longer.
