| genetic diversity and phylogeographic clustering of sivcpzptt in wild chimpanzees in cameroon. | it is now well established that the clade of simian immunodeficiency viruses (sivs) infecting west central african chimpanzees (pan troglodytes troglodytes) and western gorillas (gorilla gorilla gorilla) comprises the progenitors of human immunodeficiency virus type 1 (hiv-1). in this study, we have greatly expanded our previous molecular epidemiological survey of sivcpz in wild chimpanzees in cameroon. the new results confirm a wide but uneven distribution of sivcpzptt in p. t. troglodytes thro ... | 2007 | 17651775 |
| origin and biology of simian immunodeficiency virus in wild-living western gorillas. | western lowland gorillas (gorilla gorilla gorilla) are infected with a simian immunodeficiency virus (sivgor) that is closely related to chimpanzee and human immunodeficiency viruses (sivcpz and hiv-1, respectively) in west central africa. although existing data suggest a chimpanzee origin for sivgor, a paucity of available sequences has precluded definitive conclusions. here, we report the molecular characterization of one partial (bq664) and three full-length (cp684, cp2135, and cp2139) sivgor ... | 2009 | 19073717 |
| origin of the hiv-1 group o epidemic in western lowland gorillas. | hiv-1, the cause of aids, is composed of four phylogenetic lineages, groups m, n, o, and p, each of which resulted from an independent cross-species transmission event of simian immunodeficiency viruses (sivs) infecting african apes. although groups m and n have been traced to geographically distinct chimpanzee communities in southern cameroon, the reservoirs of groups o and p remain unknown. here, we screened fecal samples from western lowland (n = 2,611), eastern lowland (n = 103), and mountai ... | 2015 | 25733890 |
