Tóm tắt

Human immunodeficiency virus type 1 (HIV-1), the cause of human acquired immunodeficiency syndrome (AIDS), is a zoonotic infection of staggering proportions and social impact. Yet uncertainty persists regarding its natural reservoir. The virus most closely related to HIV-1 is a simian immunodeficiency virus (SIV) thus far identified only in captive members of the chimpanzee subspecies Pan troglodytes troglodytes . Here we report the detection of SIVcpz antibodies and nucleic acids in fecal samples from wild-living P. t. troglodytes apes in southern Cameroon, where prevalence rates in some communities reached 29 to 35%. By sequence analysis of endemic SIVcpz strains, we could trace the origins of pandemic (group M) and nonpandemic (group N) HIV-1 to distinct, geographically isolated chimpanzee communities. These findings establish P. t. troglodytes as a natural reservoir of HIV-1.

In contrast to plasma samples from uninfected humans which exhibit false positive Western blot reactivity to HIV-1 p24 in as many as 10 to 15% of individuals (www.fda.gov/cber/products/hiv1cam052898.htm) we have found no such nonspecific cross-reactivity of chimpanzee immunoglobulin extracted by the RNA later method from over 2000 fecal specimens.
