gastrointestinal parasite infections and self-medication in wild chimpanzees surviving in degraded forest fragments within an agricultural landscape mosaic in uganda.monitoring health in wild great apes is integral to their conservation and is especially important where they share habitats with humans, given the potential for zoonotic pathogen exchange. we studied the intestinal parasites of wild chimpanzees (pan troglodytes schweinfurthii) inhabiting degraded forest fragments amid farmland and villages in bulindi, uganda. we first identified protozoan and helminth parasites infecting this population. sixteen taxa were demonstrated microscopically (9 protozo ...201728692673
leaf-swallowing in nigerian chimpanzees: evidence for assumed self-medication.a field study in gashaka, nigeria, adds the fourth subspecies of chimpanzee, pan troglodytes vellerosus, to the list of african ape populations in which leaf-swallowing occurs. unchewed herbaceous leaves of desmodium gangeticum (leguminosae-papilionoideae) were recovered in 4% of 299 faecal samples of wild chimpanzees and clumps of sharp-edged grass leaves in 2%. the ingestion is believed to serve self-medicatory purposes because the leaves had a rough surface or were sharp-edged (which could be ...200716897194
clinical and pathologic manifestation of oesophagostomosis in african great apes: does self-medication in wild apes influence disease progression?nodular worms (oesophagostomum spp.) are common intestinal parasites found in cattle, pig, and primates including humans. in human, they are responsible for serious clinical disease called oesophagostomosis resulting from the formation of granulomas, caseous lesions or abscesses in intestinal walls. in wild great apes, the fecal prevalence of this parasite is high, but little information is available concerning the clinical signs and lesions associated. in the present study, we describe six case ...200818331558
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
oesophagostomiasis in non-human primates of gombe national park, tanzania.oesophagostomum sp. is a parasitic nematode that frequently infects wild chimpanzees. although nodular lesions are commonly associated with infection, some wild chimpanzee populations seem to tolerate oesophagostomum nodular lesions while those at gombe and other sites suffer from associated morbidity and mortality. from august 2004 to december 2013, we examined demographic (i.e., age, sex) and individual correlates (i.e., fecal consistency, oesophagostomum egg production) to oesophagostomum-ass ...201627309976
