"white-wild" (variola-like) poxvirus strains from rodents in equatorial africa.strains of variola-like virus were isolated from rodents, namely 1 each from mastomys coucha (fam. muridae) and helioscorus rufobrachium (fam. sciuridae) in the bumba zone of the equatorial province of the zaire republic. attempts to isolate the virus from 48 monkeys were negative. neutralizing antibodies were found in 1 of 7 monkey (cercopithecus ascanius schmidti) sera examined as well as in the serum of h. rufobrachium from which the virus was isolated.19767947
infanticide and social organization in the redtail monkey (cercopithecus ascanius schmidti) in the kibale forest, uganda.the redtail monkeys of the kibale forest, w. uganda, live in social groups of about 35 members with only one adult male. in one of the study groups the harem male was replaced by a new male from outside the group. this male-replacement was followed by the new male killing and eating two newborn infants in the group. infants and young juveniles older than one month were not attacked. following the infanticide the new male copulated with several adult females in the group. 8 months after this male ...1977414476
parasitology of five primates in mahale mountains national park, tanzania.parasitological surveillance in primates has been performed using coprological observation and identification of specimens from chimpanzees (pan troglodytes schweinfurthii) in mahale mountains national park, tanzania (mahale). in this study, we conducted coprological surveillance to identify the fauna of parasite infection in five primate species in mahale: red colobus (procolobus badius tephrosceles), red-tailed monkeys (cercopithecus ascanius schmidti), vervet monkeys (cercopithecus aethiops p ...201222661394
case report of helminths and lung mite infection in the red-tailed monkey, cercopithecus ascanius schmidti, in mahale mountains national park, tanzania.we documented the presence of gastrointestinal nematodes and lung mites in two red-tailed monkeys, cercopithecus ascanius schmidti, in mahale mountains national park, tanzania. we detected lung mites, pneumonyssus duttoni, in the trachea and bronchioles, and five species of nematodes, oesophagostomum pachycephalum, ternidens deminutus, streptopharagus pigmentatus, primasubulura distans, and trichuris sp. in their gastrointestinal tracts. this is the first report of a parasitological survey for t ...201020063040
a novel simian immunodeficiency virus isolated from a schmidt's guenon (cercopithecus ascanius schmidti).a novel simian immunodeficiency virus (siv) was characterized from a schmidt's guenon (cercopithecus ascanius schmidti), which was housed in a local zoo. the virus infection was detected during a routine serological screening for antibodies that were cross-reactive with sivmac antigens. infection with an immunodeficiency virus was confirmed using an inno-lia hiv confirmation assay. using dna isolated from a blot clot, a 1895 nt partial pol sequence was amplified and sequenced. phylogenetic analy ...200414718615
multifocal cryptococcus neoformans var. neoforms: infection, treatment, and monitoring by serial computed tomography in a schmidt's red-tailed guenon (cercopithecus ascanius schmidti).a 9-yr-old, female, intact schmidt's red-tailed guenon (cercopithecus ascanius schmidti) presented with an acute swelling, consistent with an abscess over the right hip. cytology, culture, and polymerase chain reaction (pcr) results from material within the abscess and serum titers were all indicative of a cryptococcus neoformans infection. thoracic radiographs and computed tomography (ct) revealed a consolidated right caudal lung lobe associated with an endobronchial mass. pulmonary cryptococcu ...201324063102
discovery and full genome characterization of a new siv lineage infecting red-tailed guenons (cercopithecus ascanius schmidti) in kibale national park, uganda.human immunodeficiency virus (hiv) type 1 and 2, the causative agents of acquired immunodeficiency syndrome (aids), emerged from african non-human primates (nhps) through zoonotic transmission of simian immunodeficiency viruses (siv). among african nhps, the cercopithecus genus contains the largest number of species known to harbor siv. however, our understanding of the diversity and evolution of sivs infecting this genus is limited by incomplete taxonomic and geographic sampling, particularly i ...201424996566
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 ...201728050688
