TL;DR: The molecular characterization of a lentivirus (SIVdeb) naturally infecting De Brazza's monkeys and the consistent clustering of SIVdeb with SIVsyk and the SIVmon/Sivmus/SIVgsn group suggests that these viruses have evolved from a common ancestor that likely infected a Cercopithecus host in the distant past.
Abstract: 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 9,227 bp in length) were amplified from uncultured blood mononuclear cell DNA of two wild-caught De Brazza's monkeys from Cameroon. In addition, partial pol sequences (650 bp) were amplified from four offspring of De Brazza's monkeys originally caught in the wild in Uganda. Full-length (9,068 bp) and partial pol (650 bp) SIVsyk sequences were also amplified from Sykes's monkeys (Cercopithecus albogularis) from Kenya. Analysis of these sequences identified a new SIV clade (SIVdeb), which differed from previously characterized SIVs at 40 to 50% of sites in Pol protein sequences. The viruses most closely related to SIVdeb were SIVsyk and members of the SIVgsn/SIVmus/SIVmon group of viruses infecting greater spot-nosed monkeys (Cercopithecus nictitans), mustached monkeys (Cercopithecus cephus), and mona monkeys (Cercopithecus mona), respectively. In phylogenetic trees of concatenated protein sequences, SIVdeb, SIVsyk, and SIVgsn/SIVmus/SIVmon clustered together, and this relationship was highly significant in all major coding regions. Members of this virus group also shared the same number of cysteine residues in their extracellular envelope glycoprotein and a high-affinity AIP1 binding site (YPD/SL) in their p6 Gag protein, as well as a unique transactivation response element in their viral long terminal repeat; however, SIVdeb and SIVsyk, unlike SIVgsn, SIVmon, and SIVmus, did not encode a vpu gene. These data indicate that De Brazza's monkeys are naturally infected with SIVdeb, that this infection is prevalent in different areas of the species' habitat, and that geographically diverse SIVdeb strains cluster in a single virus group. The consistent clustering of SIVdeb with SIVsyk and the SIVmon/SIVmus/SIVgsn group also suggests that these viruses have evolved from a common ancestor that likely infected a Cercopithecus host in the distant past. The vpu gene appears to have been acquired by a subset of these Cercopithecus viruses after the divergence of SIVdeb and SIVsyk.

TL;DR: The presence of new viruses closely related to SIVgsn in two other species reinforces the hypothesis that a recombination event between ancestral SIVs from the family Cercopithecinae is the origin of the present SIVcpz that is widespread among the chimpanzee population.
Abstract: During a large serosurvey of wild-caught primates from Cameroon, we found 2 mona monkeys (Cercopithecus mona) out of 8 and 47 mustached monkeys (Cercopithecus cephus) out of 302 with human immunodeficiency virus (HIV)-simian immunodeficiency virus (SIV) cross-reactive antibodies. In this report, we describe the full-length genome sequences of two novel SIVs, designated SIVmon-99CMCML1 and SIVmus-01CM1085, isolated from one mona (CML1) and one mustached (1085) monkey, respectively. Interestingly, these viruses displayed the same genetic organization (i.e., presence of a vpu homologue) as members of the SIVcpz-HIV type 1 lineage and SIVgsn isolated from greater spot-nosed monkeys (Cercopithecus nictitans). Phylogenetic analyses of SIVmon and SIVmus revealed that these viruses were genetically distinct from other known primate lentiviruses but were more closely related to SIVgsn all across their genomes, thus forming a monophyletic lineage within the primate lentivirus family, which we designated the SIVgsn lineage. Interestingly, mona, mustached, and greater spot-nosed monkeys are phylogenetically related species belonging to three different groups of the genus Cercopithecus, the C. mona, C. cephus, and Cercopithecus mitis groups, respectively. The presence of new viruses closely related to SIVgsn in two other species reinforces the hypothesis that a recombination event between ancestral SIVs from the family Cercopithecinae is the origin of the present SIVcpz that is widespread among the chimpanzee population.

TL;DR: Examination of fecal samples indicated a seasonally variable diet consisting mainly of seeds, fruit pith, leaves and insects (especially ants and termites), and the urgent need for the protection of the significant drill population in Korup National Park is highlighted.
Abstract: We report preliminary findings on drill population ecology, feedingecology, primate associations and conservation status in Korup NationalPark, Cameroon, based on analysis of data collected during 1,346km (620field hours) of trail patrols from February to June 2006. We encountereddrills on 25 occasions and collected 304 fecal samples. Group sizewas estimated on four occasions (Z25, Z40, Z67, Z77), and multiplemales were heard emitting the characteristic two-phase grunt of maturemale drills in two of these groups. We saw a solitary male drill once.Examination of fecal samples indicated a seasonally variable dietconsisting mainly of seeds, fruit pith, leaves and insects (especiallyants and termites). Irvingia gabonensis and Musanga cecropioides fruitsshowed the highest percentage of occurrence in May (96%) and March(75%) samples, respectively, and could be a major food source for drillsat that time. Drills were in association with at least one additionalprimate species during 57.9% of observations. These associations involvedall of the diurnal primates found in Korup (Cercopithecus mona,Cercopithecus nictitans, Cercopithecus erythrotis, Cercopithecus pogonias,Piliocolobus preussi and Cercocebus torquatus) except chimpanzees (Pantroglodytes). We discuss our findings in terms of existing knowledge aboutdrill ecology and highlight the urgent need for the protection of thesignificant drill population in Korup National Park. Am. J.
