| new species of neotrombicula (acari: trombiculidae) from african primates (galagidae and cercopithecidae). | neotrombicula kenyaensis goff and neotrombicula centrafricana goff are described as new from specimens collected from the primates galago senegalensis e. geoffroy (fam. galagidae) in kenya and allenopithecus nigroviridis (pocock) (fam. cercopithecidae) in central africa, respectively. | 1995 | 7869336 |
| human t-cell lymphotropic virus type 1 transmission dynamics in rural villages in the democratic republic of the congo with high nonhuman primate exposure. | the democratic republic of the congo (drc) has a history of nonhuman primate (nhp) consumption and exposure to simian retroviruses yet little is known about the extent of zoonotic simian retroviral infections in drc. we examined the prevalence of human t-lymphotropic viruses (htlv), a retrovirus group of simian origin, in a large population of persons with frequent nhp exposures and a history of simian foamy virus infection. we screened plasma from 3,051 persons living in rural villages in centr ... | 2021 | 33507996 |
| census, habitat preference, and polyspecific associations of six monkeys in the lomako forest, zaire. | this paper reports preliminary data on a number of poorly known cercopithecids inhabiting the lomako forest, zaire. data include those on density, biomass, group size, the relationship between group type (mono vs. polyspecific) and forest type (mixed primary, secondary, monodominant primary, and swamp), and vertical stratification. species examined are colobus angolensis, cercocebus aterrimus, cercopithecus wolfi, cercopithecus ascanius, cercopithecus neglectus, and allenopithecus nigroviridis. ... | 1994 | 31936961 |
| where's the cookie? the ability of monkeys to track object transpositions. | object permanence is the ability to represent mentally an object and follow its position even when it has disappeared from view. according to piaget's 6-stage scale of the sensorimotor period of development, it seems that object permanence appears in stage 4 and fully develops in stage 6. in this study, we investigated the ability of some species of monkeys (i.e. pig-tailed macaque, lion-tailed macaque, celebes crested macaque, barbary macaque, de brazza's monkey, l'hoest's monkey, allen's swamp ... | 2018 | 29858974 |
| medical management of leiomyomata and suspected endometriosis in an allen's swamp monkey (allenopithecus nigroviridus). | a 13-yr-old female nulliparous allen's swamp monkey (allenopitchecus nigroviridis) presented with intermittent excessive vaginal bleeding, cyclical lethargy, and a history of irregular menstrual cycles. abdominal ultrasonography revealed a subjectively thickened, irregular endometrium, multiple leiomyomata (uterine fibroids), and bilateral anechoic foci on the ovaries. treatment was initiated with leuprolide acetate i.m. monthly for 6 mo. recheck ultrasound at 3 mo showed a decrease in leiomyoma ... | 2015 | 26667550 |
| digestive retention times for allen's swamp monkey and l'hoest's monkey: data with implications for the evolution of cercopithecine digestive strategy. | primates access energy from plant fiber via bacterial fermentation in either a modified forestomach ('foregut'), a caecocolic ('hindgut') chamber of the large intestine, or both. longer digestive retention times allow for more complete fermentation; as such, primates that consume an herbivorous diet high in fiber are expected to have both relatively and absolutely longer retention times than those mammals that rely on more readily digestible plant foods, such as fruit. we used particulate marker ... | 2012 | 22691202 |
| high prevalences and a wide genetic diversity of simian retroviruses in non-human primate bushmeat in rural areas of the democratic republic of congo. | like the majority of emerging infectious diseases, hiv and htlv are of zoonotic origin. here we assess the risk of cross-species transmissions of their simian counterparts, siv and stlv, from non-human primates (nhp) to humans in the democratic republic of congo (drc). a total of 331 samples, derived from nhp bushmeat, were collected as dried blood spots (dbs, n = 283) or as tissue samples (n = 36) at remote forest sites mainly in northern and eastern drc. siv antibody prevalences in dbs were es ... | 2017 | 28050688 |
| variation in guenon skulls (i): species divergence, ecological and genetic differences. | guenons are the most diverse clade of african monkeys. they have varied ecologies, include arboreal and terrestrial species, and can be found in nearly every region of sub-saharan africa. species boundaries are often uncertain, with a variable number of species and subspecies mostly recognised on the basis of their geographic distribution and pelage. if guenon soft tissue patterns show high variability, the same does not seem to hold for skull morphology. guenon skulls are traditionally consider ... | 2008 | 18191179 |
| sex chromosome phylogenetics indicate a single transition to terrestriality in the guenons (tribe cercopithecini). | this is the first molecular study to trace the evolutionary transition in substrate preference across a primate radiation. we surveyed 20 guenons (tribe cercopithecini) and 4 outgroup taxa for two y-chromosomal genes, tspy ( approximately 2240 bp) and sry ( approximately 780 bp), and one x-chromosomal intergenic region ( approximately 1600 bp) homologous to a fragment of human xq13.3. parsimony and maximum likelihood analyses of the sex chromosomal datasets consistently cluster the three terrest ... | 2004 | 14871564 |

| molecular and phylogenetic analyses of 16 novel simian t cell leukemia virus type 1 from africa: close relationship of stlv-1 from allenopithecus nigroviridis to htlv-1 subtype b strains. | a serological survey searching for antibodies reacting with human t-cell leukemia virus type 1 (htlv-1) antigens was performed on a series of 263 sera/plasma obtained from 34 monkey species or subspecies, originating from different parts of africa. among them, 34 samples exhibited a typical htlv-1 western blot pattern. polymerase chain reaction was performed with three primer sets specific either to htlv-1/stlv-1 or htlv-2 and encompassing gag, pol, and tax sequences, on genomic dna from periphe ... | 2001 | 11531406 |
| reciprocal painting between humans, de brazza's and patas monkeys reveals a major bifurcation in the cercopithecini phylogenetic tree. | we report on reciprocal painting between humans and two cercopithecini species, erythrocebus patas (patas monkey) and cercopithecus neglectus (de brazza's monkey). both human and monkeys chromosome-specific probes were made by degenerate oligonucleotide primed pcr (dop-pcr) from flow sorted chromosomes. metaphases of both monkey species were first hybridized with human chromosome-specific probes and then human metaphases were hybridized with chromosome paints from each monkey species. the human ... | 2005 | 15545727 |
| screening for simian foamy virus infection by using a combined antigen western blot assay: evidence for a wide distribution among old world primates and identification of four new divergent viruses. | simian foamy viruses (sfvs) belong to a genetically and antigenically diverse class of retroviruses that naturally infect a wide range of nonhuman primates (nhps) and can also be transmitted to humans occupationally exposed to nhps. current serologic detection of sfv infection requires separate western blot (wb) testing by using two different sfv antigens [sfv(agm) (african green monkey) and sfv(cpz) (chimpanzee)]. however, this method is labor intensive and validation is limited to only small n ... | 2003 | 12758172 |
