| naturally acquired simian retrovirus infections in central african hunters. | hunting and butchering of wild non-human primates infected with simian immunodeficiency virus (siv) is thought to have sparked the hiv pandemic. although siv and other primate retroviruses infect laboratory workers and zoo workers, zoonotic retrovirus transmission has not been documented in natural settings. we investigated zoonotic infection in individuals living in central africa. | 2004 | 15043960 |
| prevalence and genetic diversity of simian immunodeficiency virus infection in wild-living red colobus monkeys (piliocolobus badius badius) from the taï forest, côte d'ivoire sivwrc in wild-living western red colobus monkeys. | numerous african primates are infected with simian immunodeficiency viruses (sivs). it is now well established that the clade of sivs infecting west-central african chimpanzees (pan troglodytes troglodytes) and western gorillas (gorilla gorilla gorilla) represent the progenitors of human immunodeficiency virus type 1 (hiv-1), whereas hiv-2 results from different cross-species transmissions of sivsmm from sooty mangabeys (cercocebus atys atys). we present here the first molecular epidemiological ... | 2008 | 17916449 |
| 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 |
| molecular epidemiology of simian immunodeficiency virus infection in wild-living gorillas. | chimpanzees and gorillas are the only nonhuman primates known to harbor viruses closely related to hiv-1. phylogenetic analyses showed that gorillas acquired the simian immunodeficiency virus sivgor from chimpanzees, and viruses from the sivcpz/sivgor lineage have been transmitted to humans on at least four occasions, leading to hiv-1 groups m, n, o, and p. to determine the geographic distribution, prevalence, and species association of sivgor, we conducted a comprehensive molecular epidemiologi ... | 2010 | 19906908 |
| debilitating clinical disease in a wild-born captive western lowland gorilla (gorilla gorilla gorilla) co-infected with varicella zoster virus (vzv) and simian t-lymphotropic virus (stlv). | a wild-born, 34-yr-old female western lowland gorilla (gorilla gorilla gorilla) was transferred between zoologic collections in the united kingdom. adjustment to its new environment was difficult and a series of health problems ensued. progressive severe illness of multiple etiologies, and a failure to respond to multiple therapies, led to its euthanasia 5 mo later. disease processes included severe thoracic and axillary cutaneous ulceration of t2-3 dermatome distribution, gastroenteritis, ulcer ... | 2010 | 21370655 |
| noninvasive follow-up of simian immunodeficiency virus infection in wild-living nonhabituated western lowland gorillas in cameroon. | simian immunodeficiency viruses infecting western lowland gorillas (sivgor) are closely related to hiv-1 and are most likely the ancestors of hiv-1 groups o and p. at present, limited data are available on genetic diversity, transmission, viral evolution, and pathogenicity of sivgor in its natural host. between 2004 and 2011, 961 putative gorilla fecal samples were collected at the campo ma'an national park, cameroon. among them, 16% cross-reacted with hiv-1 antibodies, corresponding to at least ... | 2012 | 22740419 |
