[cytogenetics of cercopithecus (mona) campbelli. comparison with other cercopithecus species and man (author's transl)].the karyotype of c. (mona) campbelli campbelli is described after applying various banding techniques. after comparing this karyotype with those of numerous other cercopithecus species it becomes possible to situate c. (m.) c. campbelli in the phylogeny of the group. a comparison with the human karyotype, after high resolution banding, shows that both species differ by some forty rearrangements, essentially fissions and inversions. a fission of the chromosome homologous to the human no. 10 occur ...19816974522
seroepidemiologic, molecular, and phylogenetic analyses of simian t-cell leukemia viruses (stlv-i) from various naturally infected monkey species from central and western africa.a study of simian t-cell lymphoma/leukemia virus infection, conducted on 747 nonhuman primates belonging to 14 different species in central and western africa, indicated that 4 species (cercopithecus aethiops, erythrocebus patas, papio doguera, and cercopithecus mona pogonias) had a high prevalence of seropositivity to simian t-cell lymphoma/leukemia virus type i (stlv-i). the other nonhuman primate species, however, had negative or low levels of anti-htlv-i antibodies. stlv-i pol and env dna wa ...19948259665
group size and group composition of the mona monkey (cercopithecus mona) on the island of grenada, west indies.cercopithecus, the genus of guenons, is the largest of the african primate genera, and yet more than half of the species belonging to this group have never been the focus of a long-term field study. in this paper, i present data on group size and composition for a previously unstudied population of guenons on the caribbean island of grenada. the mona monkey, cercopithecus mona, was introduced to grenada from africa approximately 200-300 years ago. two types of social groups were found for cercop ...19979327099
capture techniques and morphological measurements of the mona monkey (cercopithecus mona) on the island of grenada, west indies.morphological measurements were collected from 12 wild and 12 captive mona monkeys (cercopithecus mona) on the caribbean island of grenada. mona monkeys were introduced to grenada from africa approximately 200 to 300 years ago during the slave trade era. wild monkeys were captured using either 1) a baited treadle-door trap and anesthetic-filled darts fired from a blowpipe, or 2) rifle-fired anesthetic-filled darts. all wild monkeys were released back into the forest after capture and were seen w ...19989584890
molecular separation of oesophagostomum stephanostomum and oesophagostomum bifurcum (nematoda: strongyloidea) from non-human primates.the its-2 sequences for adult specimens of oesophagostomum stephanostomum from the common chimpanzee and oesophagostomum bifurcum from the mona monkey were determined. for both species, the length and gc content of the its-2 sequences were 216 bp and 43%, respectively. while there was no unequivocal sequence difference among individual worms representing each of the two species, five (2.3%) interspecific nucleotide differences were detected. these differences were associated with the presence of ...199910501618
screening for haplotypic variability within oesophagostomum bifurcum (nematoda) employing a single-strand conformation polymorphism approach.genetic markers in the mitochondrial genome have proven useful for population genetic studies because of their maternal inheritance and relatively high evolutionary rates. in this study, we exploited the high resolution capacity of pcr-coupled single-strand conformation polymorphism (sscp) to screen for sequence variation in part of the cytochrome c oxidase subunit 1 gene (p cox 1) among individuals of the parasitic nematode, oesophagostomum bifurcum from human or mona monkey hosts from africa. ...200212144769
characterization of a novel simian immunodeficiency virus (sivmonng1) genome sequence from a mona monkey (cercopithecus mona).a novel simian immunodeficiency virus (siv) sequence has been recovered from rna extracted from the serum of a mona monkey (cercopithecus mona) wild born in nigeria. the sequence was obtained by using novel generic (degenerate) pcr primers and spans from two-thirds into the gag gene to the 3' poly(a) tail of the sivmonng1 rna genome. analysis of the open reading frames revealed that the sivmonng1 genome codes for a vpu protein, in addition to gag, pol, vif, vpr, tat, rev, env, and nef proteins. ...200312768007

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 ...200415220449
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 ...200515956597
definition of genetic markers in nuclear ribosomal dna for a neglected parasite of primates, ternidens deminutus (nematoda: strongylida)--diagnostic and epidemiological implications.ternidens deminutus (strongylida) is a parasitic nematode infecting non-human and human primates in parts of africa, asia and the pacific islands. the present study genetically characterized t. deminutus and defined genetic markers in nuclear ribosomal dna (rdna) as a basis for developing molecular-diagnostic tools. the sequences of the second internal transcribed spacer (its-2) of rdna were determined for adult specimens of t. deminutus (nematoda: strongylida: oesophagostominae) from the olive ...200516174419
oesophagostomum bifurcum in non-human primates is not a potential reservoir for human infection in ghana.in northern togo and ghana, human infection with the parasitic nematode oesophagostomum bifurcum is of major health importance. elsewhere, oesophagostomiasis is considered a zoonotic infection, non-human primates being the natural host. we examined 349 faecal samples of the olive baboon, mona monkey and black and white colobus monkey from two geographically distinct areas in ghana, outside the region endemic for o. bifurcum in humans. using both microscopy and species-specific pcr, we found a hi ...200516359413
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 ...200717156809
note on drill (mandrillus leucophaeus) ecology and conservation status in korup national park, southwest cameroon.we report preliminary findings on drill population ecology, feeding ecology, primate associations and conservation status in korup national park, cameroon, based on analysis of data collected during 1,346 km (620 field hours) of trail patrols from february to june 2006. we encountered drills on 25 occasions and collected 304 fecal samples. group size was estimated on four occasions (> or =25, > or =40, > or =67, > or =77), and multiple males were heard emitting the characteristic two-phase grunt ...200817922527
simian t-lymphotropic virus diversity among nonhuman primates, cameroon.cross-species transmission of retroviruses is common in cameroon. to determine risk for simian t-cell lymphotropic virus (stlv) transmission from nonhuman primates to hunters, we examined 170 hunter-collected dried blood spots (dbs) from 12 species for stlv. pcr with generic tax and group-specific long terminal repeat primers showed that 12 (7%) specimens from 4 nonhuman primate species were infected with stlv. phylogenetic analyses showed broad diversity of stlv, including novel stlv-1 and stlv ...200919193260
distribution and abundance of sacred monkeys in igboland, southern nigeria.although primates are hunted on a global scale, some species are protected against harassment and killing by taboos or religious doctrines. sites where the killing of sacred monkeys or the destruction of sacred groves is forbidden may be integral to the conservation of certain species. in 2004, as part of a distribution survey of sclater's guenon (cercopithecus sclateri) in southern nigeria, we investigated reports of sacred monkeys in the igbo-speaking region of nigeria. we confirmed nine new s ...200919408287
genetic characterization of the complete genome of a highly divergent simian t-lymphotropic virus (stlv) type 3 from a wild cercopithecus mona monkey.the recent discoveries of novel human t-lymphotropic virus type 3 (htlv-3) and highly divergent simian t-lymphotropic virus type 3 (stlv-3) subtype d viruses from two different monkey species in southern cameroon suggest that the diversity and cross-species transmission of these retroviruses are much greater than currently appreciated.200919860877
simian immunodeficiency virus envelope glycoprotein counteracts tetherin/bst-2/cd317 by intracellular sequestration.tetherin is an ifn-inducible restriction factor that inhibits hiv-1 particle release in the absence of the hiv-1 countermeasure, viral protein u (vpu). although ubiquitous in hiv-1 and simian immunodeficiency viruses from chimpanzees, greater spot nosed monkeys, mustached monkeys, and mona monkeys, other primate lentiviruses do not encode a vpu protein. here we demonstrate that siv from tantalus monkeys (sivtan) encodes an envelope glycoprotein (sivtan env) able to counteract tetherin from tanta ...200919864625
the presence of a vpu gene and the lack of nef-mediated downmodulation of t cell receptor-cd3 are not always linked in primate lentiviruses.nef is an accessory protein critical for the ability of human and simian immunodeficiency viruses (hiv and siv) to replicate efficiently in their respective hosts. previous analyses of members of 15 different primate lentivirus lineages revealed a link between nef function and the presence of a vpu gene. in particular, nef proteins of all vpu-containing viruses had lost their ability to downmodulate the t cell (tcr-cd3) receptor. here we examined nef proteins from eight additional siv lineages, ...201021068258
gastrointestinal parasites of captive and free-roaming primates at the afi mountain primate conservation area in calabar, nigeria and their zoonotic implications.a study on the gastrointestinal parasites among free-living and captive primates at the afi mountain, primate conservation area in calabar, nigeria was undertaken for the first time to ascertain their zoonotic implications. faecal samples were subjected to direct smear, floatation, quantitative estimation of helminth eggs (epg) and oocysts (opg), larval isolation and identification by modified baerman's technique and oocyst sporulation for specie identification. out of the 108 primates examined, ...201122308652
full-length genome analyses of two new simian immunodeficiency virus (siv) strains from mustached monkeys (c. cephus) in gabon illustrate a complex evolutionary history among the sivmus/mon/gsn lineage.the simian immunodeficiency virus (siv) mus/mon/gsn lineage is a descendant of one of the precursor viruses to the hiv-1/sivcpz/gor viral lineage. sivmus and sivgsn were sequenced from mustached and greater spot nosed monkeys in cameroon and sivmon from mona monkeys in cameroon and nigeria. in order to further document the genetic diversity of sivmus, we analyzed two full-length genomes of new strains identified in gabon. the whole genomes obtained showed the expected reading frames for gag, pol ...201425054885
cytogenetic study of a cercopithecus pogonias grayi x cercopithecus mona mona hybrid.the g- and c-banded karyotypes of hybrid born of the cross between a male cercopithecus pogonias grayi (2 n = 72 xy) and a female c. mona mona (2 n = 68 xx) are reported. the chromosome number is 2 n = 70 and equals half the total number of parental chromosomes. a correlation between the hybrid karyotype and those of its parents is proposed. the typical autosomes of c. pogonia grayi are again found in the young hybrids.19827095658
short-term effects of aflatoxin b1 on serum lipids in subhuman primates.aflatoxin b1 significantly depressed serum lipid levels in specimens of cercopithecus aethiops, cercopithecus mona, erythrocebus patas and papio anubis. serum cholesterol, total phospholipids and total lipids were not affected to the same extent.1979113622
loss of cxcr6 coreceptor usage characterizes pathogenic lentiviruses.pandemic hiv-1 originated from the cross-species transmission of sivcpz, which infects chimpanzees, while sivcpz itself emerged following the cross-species transmission and recombination of monkey sivs, with env contributed by the sivgsn/mus/mon lineage that infects greater spot-nosed, mustached and mona monkeys. sivcpz and hiv-1 are pathogenic in their respective hosts, while the phenotype of their sivgsn/mus/mon ancestors is unknown. however, two well-studied siv infected natural hosts, sooty ...201829659623
population genomics reveals incipient speciation, introgression, and adaptation in the african mona monkey (cercopithecus mona).guenons (tribe cercopithecini) are the most widely distributed non-human primate in the tropical forest belt of africa and show considerable phenotypic, taxonomic, and ecological diversity. however, genomic information for most species within this group is still lacking. here, we present a high-quality de novo genome (total 2.90 gb, contig n50 equal to 22.7 mb) of the mona monkey (cercopithecus mona), together with genome resequencing data of 13 individuals sampled across nigeria. our results sh ...202032986826
cpg frequency in the 5' third of the env gene determines sensitivity of primary hiv-1 strains to the zinc-finger antiviral protein.cpg dinucleotide suppression has been reported to allow hiv-1 to evade inhibition by the zinc-finger antiviral protein (zap). here, we show that primate lentiviruses display marked differences in cpg frequencies across their genome, ranging from 0.44% in simian immunodeficiency virus sivwrc from western red colobus to 2.3% in sivmon infecting mona monkeys. moreover, functional analyses of a large panel of human and simian immunodeficiency viruses revealed that the magnitude of cpg suppression do ...202031937644
assessment of environmental enrichment for different primate species under low budget: a case study.the 2011 european union zoo inquiry presented evidence that most zoos fail to achieve adequate levels of nonhuman animal welfare. appropriate environmental enrichment (ee) can play a role in the promotion of welfare. however, financial and staff constraints frequently make it challenging to implement ee on a daily basis. the aim of this study was to test how individuals of three different nonhuman primate species at the maia zoo in portugal (white-handed gibbons, hylobates lar; mona monkeys, cer ...201829299937
haemogram and serum biochemical values of four indigenous species of monkeys in south west nigeria.haematological and serum biochemical values are useful guides and biomarkers in health and diseases for reaching a diagnosis, estimating disease prognosis and monitoring treatment progress, in mammals. reference ranges for some parameters differ among species of mammals and between sexes within a species. there is dearth of information on standard reference value for blood parameters for nigerian indigenous monkeys. whole blood and serum samples obtained from 50 apparently healthy adult monkeys ...201931449275
morphological structures and protrusive cranial border guidance of the temporomandibular joint of cercopithecus mona.morphological parameters of the temporomandibular joint (tmj) of cercopithecus mona were analyzed by sagittal medial/lateral slicing of the entire joint. the slice contours of the osseous structures of the joint surfaces were approximated by circles. in this manner, the main parameter of the protrusive cranial border guidance, the protrusive dimeric link chain (dlc), could be measured. in each joint, all slices yielded protrusive dlcs which were nearly parallel to each other. in medial/lateral d ...200717695987
aspects of morphology and guidance of the human temporomandibular joint.examinations of the curvature morphology of the temporomandibular joints (tmjs) in macerated human skulls yielded that in initial protrusive cranial border motion, parts of the condylar articulating surfaces are only functional under force transmission. these areas were found on the lateral-central side of the condyle. in contrast to the cercopithecus mona, a monkey species, the human tmj apparently possesses a distinctly higher spatial performance range.200717695988
high resolution dna fingerprinting by aflp to study the genetic variation among oesophagostomum bifurcum (nematoda) from human and non-human primates from ghana.an aflp approach was established to investigate genetic diversity within oesophagostomum bifurcum (order strongylida) from human and non-human primates. evaluation of different combinations of restriction enzymes (n = 8) and primers (n = 29) demonstrated that the use of hindiii/bglii digested templates and primers with the selective nucleotides + ag/ +ac, respectively, was the most effective for the analysis of o. bifurcum dna. a total of 63 o. bifurcum adults from human, patas monkey, mona monk ...200515727072
genetic substructuring within oesophagostomum bifurcum (nematoda) from human and non-human primates from ghana based on random amplified polymorphic dna analysis.random amplified polymorphic dna (rapd) was used to study genetic variation within oesophagostomum bifurcum in ghana. four different decamer primers were used for the amplification of dna from individual o. bifurcum adults (n = 41) from humans and non-human primates (including the mona monkey, patas monkey and olive baboon) from different geographic regions. analysis of the amplicons from all 41 nematodes by high resolution, denaturing polyacrylamide gel electrophoresis defined a total of 326 in ...200415306716
screening for nucleotide variations in ribosomal dna arrays of oesophagostomum bifurcum by polymerase chain reaction-coupled single-strand conformation polymorphism.we exploited the high resolution capacity of polymerase chain reaction (pcr)-coupled single-strand conformation polymorphism (sscp) to screen for sequence variation in the second internal transcribed spacer (its-2) of ribosomal dna (rdna) among 77 individuals representing oesophagostumum bifurcum from human or mona monkey hosts from africa. sscp analysis revealed distinct profiles among some of the individuals, and sequence analysis of representative samples defined different its-2 sequence type ...199910424472
