treponema infection associated with genital ulceration in wild baboons.the authors describe genital alterations and detailed histologic findings in baboons naturally infected with treponema pallidum. the disease causes moderate to severe genital ulcerations in a population of olive baboons (papio hamadryas anubis) at lake manyara national park in tanzania. in a field survey in 2007, 63 individuals of all age classes, both sexes, and different grades of infection were chemically immobilized and sampled. histology and molecular biological tests were used to detect an ...201121411621
validation of serological tests for the detection of antibodies against treponema pallidum in nonhuman primates.there is evidence to suggest that the yaws bacterium (treponema pallidum ssp. pertenue) may exist in non-human primate populations residing in regions where yaws is endemic in humans. especially in light of the fact that the world health organizaiton (who) recently launched its second yaws eradication campaign, there is a considerable need for reliable tools to identify treponemal infection in our closest relatives, african monkeys and great apes. it was hypothesized that commercially available ...201525803295
high prevalence of antibodies against the bacterium treponema pallidum in senegalese guinea baboons (papio papio).the bacterium treponema pallidum is known to cause syphilis (ssp. pallidum), yaws (ssp. pertenue), and endemic syphilis (ssp. endemicum) in humans. nonhuman primates have also been reported to be infected with the bacterium with equally versatile clinical manifestations, from severe skin ulcerations to asymptomatic. at present all simian strains are closely related to human yaws-causing strains, an important consideration for yaws eradication. we tested clinically healthy guinea baboons (papio p ...201526588087
