Agropolis, BPMontpellier cedex 1, France. Received Jan 30; Accepted May Abstract In the present study, we describe a new simian immunodeficiency virus SIVdesignated SIVgsn, naturally infecting greater spot-nosed monkeys Cercopithecus nictitans in Cameroon.

First of all, they differ in their genomic organization. When comparing the two SIVgsn Env sequences with that of SIVcpz, a remarkable conservation was seen in the V3 loop, indicating a possible common origin for the envelopes of these two viruses.

The habitats of the two subspecies of chimpanzees infected by SIVcpz overlap the geographic ranges of greater spot-nosed monkeys and other monkey species, allowing cross-species transmission and recombination between coinfecting viruses.

AIDS is caused by two lentiviruses, human immunodeficiency viruses type 1 HIV-1 and type 2 HIV-2both of zoonotic origin, which find their closest simian relatives in the common chimpanzee Pan troglodytes and the sooty mangabey Cercocebus atysrespectively.

In addition to these simian immunodeficiency viruses SIVsserological or molecular evidence for other SIVs has been reported in at least 30 African nonhuman primates 16 Based on sequence similarity of the fully characterized viruses, SIVs are classified into six approximately equidistant phylogenetic lineages: Two other recently characterized SIV strains from wild mandrills in Cameroon SIVmnd2 3539 and from red-capped mangabeys in Nigeria SIVrcm 4 cannot be classified into one of the six lentivirus lineages because of a mosaic genome.

SIVs belong to the lentivirus subfamily of retroviruses and can display different genomic organizations. Phylogenetic relationships among the lentiviruses clearly indicate a common origin and provide evidence that some of the viruses have evolved in a host-dependent fashion, as is the case for African green monkeys 12228 and within the Cercopithecus lhoesti superspecies 3.

But there are also multiple examples of cross-species transmissions from simians to humans and between simians.

The colobus and chimps in Gombe feed in the same area, making it necessary for the colobus monkeys to intimidate all sex and age classes in the chimp population. 7.

KATE CHOPIN () She was an American author of short stories and novels. She is now considered by some to have been a forerunner of feminist authors of the 20th century. Chopin was born Katherine O'Flaherty in St. Louis, Missouri. Her father, Thomas O'Flaherty, was a successful businessman who had emigrated from Galway, Ireland.

Indeed, it appears now that the presence of human immunodeficiency viruses HIV-1 and HIV-2 in the human population results from at least eight independent transmission events of viruses naturally infecting chimpanzees and sooty mangabeys SIV infection of baboons and patas monkeys by viruses derived from the local sympatric species of African green monkeys confirms that simian-to-simian cross-species transmissions also occur in the wild 523 In addition, phylogenetic analyses also provided evidence for mosaic SIV genomes in at least three nonhuman primate species, West African sabaeus monkeys SIVsabred-capped mangabeys SIVrcmand mandrills SIVmnd2 4152235suggesting that recombination events have occurred between viruses in vivo.

These observations indicate that both cross-species transmission and coinfection with highly divergent viral strains are possible. For a better understanding of the evolutionary relationships of primate lentiviruses, which are becoming more and more complex, characterization of SIVs from other nonhuman primates species is essential.

It is now widely accepted that HIV-1 came from a zoonotic transmission from SIVcpz to humans, but there is less evidence on whether chimpanzees are the natural reservoir for this group of lentiviruses or whether they became infected from another species.

In this context, we initiated a large seroprevalence survey of wild-born monkeys in Cameroon 29 and identified several greater spot-nosed monkeys Cercopithecus nictitans whose sera contained antibodies cross-reacting with HIV-1 envelope gene products. The greater spot-nosed monkeys are found in lowland forest across the Congo Basin and as far west as Nigeria and are known to be hunted by chimpanzees for food.

This paper describes the genetic characterization of a novel primate lentivirus found in greater spot-nosed monkeys from Cameroon. Blood samples were obtained from greater spot-nosed monkeys C.

All the animals were caught in the wild in Cameroon. A total of animals were sampled as bushmeat upon arrival at markets in Yaounde, in surrounding villages, or at logging concessions in southeastern Cameroon, and 44 animals were sampled as pets from the same areas.

All primate samples were obtained with approval from the Cameroonian Ministry of Environment and Forestry. The bushmeat samples were obtained by employing a strategy specifically designed not to increase further the demand for bushmeat.

Women preparing and preserving the meat for subsequent sale and hunters already involved in the trade were asked for permission to sample blood and tissues from carcasses, which were then returned to their owners. For the bushmeat animals, blood was collected by intracardiac puncture.

Information provided by the owners indicated that most of the animals had died 12 to 72 h prior to sampling. Plasma and cells were separated on site by Ficoll gradient centrifugation. This test configuration includes HIV-1 and HIV-2 recombinant proteins and synthetic peptides that are coated as discrete lines onto a nylon strip.The paper analyzes Christophe Boesch's and Hedwige Boesch-Achermann's article "In Dim Forest, Bright Chimps".

The scientists were less surprised by the Talchimps meat eating habits and more by their cooperation in their hunting ways. The authors have pointed out the superior development of the chimpanzees’ use of their hands.
