| detection of g-c rich heterochromatin by 5-azacytidine in mammals. | a new effect of 5-acr (5-azacytidine), observed in fibroblast or kidney cell cultures is described in the calf (bos taurus) and in some selected primates (cebus capucinus, erythrocebus patas, and cercopithecus cephus). this cytidine analogue, used at low doses during the last late s phase, prevents the condensation of r-band positive heterochromatin (g-c rich segments). thus, 5-acr treatment can be used as a simple method for the detection of g-c rich heterochromatin. | 1981 | 6164628 |
| [vocal behavior of adult males and superspecific organization in polyspecific troops of monkeys]. | analysis of the vocal behaviour of adult males from different species of cercopithecus monkeys in a polyspecific troop shows important species differences, which suggest a superspecific organization upon which the extraordinary stability of certain polyspecific associations can depend. in the community studied, the male cercopithecus pogonias generally controlled the formation and disbanding of polyspecific troops, coordinated their movements and the spacing between troops, while cercopithecus c ... | 1983 | 6684083 |
| mutations in ccr5-coding sequences are not associated with siv carrier status in african nonhuman primates. | african monkeys can be naturally infected with siv but do not progress to aids. since mutations in the human ccr5 gene have been shown to influence susceptibility to hiv infection and disease progression, we have now investigated whether mutations in ccr5-coding sequences in african nonhuman primates can explain species-specific differences in susceptibility to lentiviral infection. the animals studied comprise chronically infected monkeys corresponding to four natural hosts of siv (cercopithecu ... | 1999 | 10408730 |

| simian t-cell leukemia virus (stlv) infection in wild primate populations in cameroon: evidence for dual stlv type 1 and type 3 infection in agile mangabeys (cercocebus agilis). | three types of human t-cell leukemia virus (htlv)-simian t-cell leukemia virus (stlv) (collectively called primate t-cell leukemia viruses [ptlvs]) have been characterized, with evidence for zoonotic origin from primates for htlv type 1 (htlv-1) and htlv-2 in africa. to assess human exposure to stlvs in western central africa, we screened for stlv infection in primates hunted in the rain forests of cameroon. blood was obtained from 524 animals representing 18 different species. all the animals w ... | 2004 | 15078952 |
| new simian immunodeficiency virus infecting de brazza's monkeys (cercopithecus neglectus): evidence for a cercopithecus monkey virus clade. | nearly complete sequences of simian immunodeficiency viruses (sivs) infecting 18 different nonhuman primate species in sub-saharan africa have now been reported; yet, our understanding of the origins, evolutionary history, and geographic distribution of these viruses still remains fragmentary. here, we report the molecular characterization of a lentivirus (sivdeb) naturally infecting de brazza's monkeys (cercopithecus neglectus). complete sivdeb genomes (9,158 and 9227 bp in length) were amplifi ... | 2004 | 15220449 |
| characterization of a novel vpu-harboring simian immunodeficiency virus from a dent's mona monkey (cercopithecus mona denti). | we report the identification of a new simian immunodeficiency virus (siv), designated sivden, in a naturally infected dent's mona monkey (cercopithecus mona denti), which was kept as pet in kinshasa, capital of the democratic republic of congo. sivden is genetically distinct from the previously characterized primate lentiviruses. analysis of the full-length genomic sequence revealed the presence of a vpu open reading frame. this gene is also found in the virus lineage of human immunodeficiency v ... | 2005 | 15956597 |
| bartonella quintana and rickettsia felis in gabon. | we detected rickettsia felis dna in ctenocephalides felis and bartonella quintana dna in 3 pulex irritans fleas taken from a pet cercopithecus cephus monkey in gabon, sub-saharan africa. this is the first report of b. quintana in the human flea. | 2005 | 16318727 |
| full-length sequence analysis of sivmus in wild populations of mustached monkeys (cercopithecus cephus) from cameroon provides evidence for two co-circulating sivmus lineages. | mustached monkeys (cercopithecus cephus), which form a significant component of primate bushmeat in west central africa, are infected with simian immunodeficiency virus (sivmus). we identified and genetically characterized five new sivmus strains infecting wild living mustached monkeys from cameroon. phylogenetic analysis of partial pol sequences revealed that sivmus strains form two distinct groups within the clade comprised of lentiviruses isolated from cercopithecus nictitans (sivgsn), cercop ... | 2007 | 17156809 |
| identification and molecular characterization of new stlv-1 and stlv-3 strains in wild-caught nonhuman primates in cameroon. | humans and simian species are infected by deltaretroviruses (htlv and stlv respectively), which are collectively called primate t-cell lymphotropic viruses (ptlvs). in humans, four types of htlv have been described (htlv-1 to -4) with three of them having closely related simian virus analogues named stlv-1, 2 and 3. in this study, our aim was to search for a simian htlv-4-related virus and to document and characterize further the diversity of stlv infections in wild primate populations. we scree ... | 2008 | 17976676 |
| [ecology of stomoxyine fulies (diptera: muscidae) in gabon. ii. blood meals analysis a nd epidemiologic consequences]. | to determine the origin of stomoxyine fly bloodmeals (diptera: muscidae) in gabon, 1,021 flies belonging to seven different species of stomoxys were captured and dissected in the area of makokou. in total, 798 were not blood-fed and 223 bloodmeals could be gathered on filter paper. the identification of the origin of these meals was made by amplification of mitochondrial cytb gene, then heteroduplex technique by using the gambian rat (cricetomys gambianus) as driver. samples of fauna, collected ... | 2008 | 19202770 |
| extensive survey on the prevalence and genetic diversity of sivs in primate bushmeat provides insights into risks for potential new cross-species transmissions. | to evaluate the risk of cross-species transmissions of sivs from non-human primates to humans at the primate/hunter interface, a total of 2586 samples, derived from primate bushmeat representing 11 different primate species, were collected at 6 distinct remote forest sites in southeastern cameroon and in yaoundé, the capital city. siv prevalences were estimated with an updated siv lineage specific gp41 peptide elisa covering the major part of the siv diversity. siv positive samples were confirme ... | 2010 | 19393772 |
| simian immunodeficiency virus sivagm from african green monkeys does not antagonize endogenous levels of african green monkey tetherin/bst-2. | the vpu accessory gene that originated in the primate lentiviral lineage leading to human immunodeficiency virus type 1 is an antagonist of human tetherin/bst-2 restriction. most other primate lentivirus lineages, including the lineage represented by simian immunodeficiency virus sivagm from african green monkeys (agms), do not encode vpu. while some primate lineages encode gene products other than vpu that overcome tetherin/bst-2, we find that sivagm does not antagonize physiologically relevant ... | 2009 | 19726508 |
| influence of habitat and seasonal variation on wild mammal diversity and distribution with special reference to the trypanosoma brucei gambiense host-reservoir in bipindi (cameroon). | to evaluate the role of wildlife in the resurgence and perenisation of human african trypanosomiasis (hat), we investigated the influence of habitat and seasonal variations on the diversity and spatial distribution of wild mammals, with special reference to those recognised as potential host-reservoirs of trypanosoma brucei gambiense in bipindi (southwestern cameroon). to achieve this, we carried out transect surveys in four habitat types over two years. a total of 31 mammal species were recorde ... | 2009 | 19732737 |
