hyper-variable regions in 18s rdna of strongyloides spp. as markers for species-specific diagnosis.four hyper-variable regions (hvr-i to -iv) found in 18s ribosomal dna sequences were compared among 34 isolates of 15 species of the genus strongyloides to evaluate their diagnostic value. hvr-i to -iii were short, and plural species exhibit the same nucleotide arrangement. meanwhile, hvr-iv had 23 to 39 nucleotides, showing species-specific arrangements, except strongyloides ransomi and strongyloides venezuelensis, which had the same nucleotide sequence in hvr-iv but were readily distinguished ...200919050926
molecular identification of the causative agent of human strongyloidiasis acquired in tanzania: dispersal and diversity of strongyloides spp. and their hosts.in order to identify the causative agent of imported strongyloidiasis found in a japanese mammalogist, who participated in a field survey in tanzania, the hyper-variable region iv (hvr-iv) of 18s ribosomal dna and partial mitochondrial cytochrome c-oxidase subunit 1 gene (cox1) were analyzed and compared with strongyloides fuelleborni collected from apes and monkeys of africa and japan, and s. stercoralis from humans, apes and dogs. the hvr-iv and cox1 of the patient's worms were identical to or ...201020621633
demographic and ecological effects on patterns of parasitism in eastern chimpanzees (pan troglodytes schweinfurthii) in gombe national park, tanzania.from january 2006 to january 2008, we collected 1,045 fecal samples from 90 individually-recognized, free-ranging, eastern chimpanzees (pan troglodytes schweinfurthii) inhabiting gombe national park, tanzania to determine how patterns of parasitism are affected by demographic and ecological covariates. seventeen parasite species were recovered, including eight nematodes (oesophagostomum sp., necator sp., probstmayria gombensis, strongyloides fulleborni, ascaris sp., trichuris sp., abbreviata cau ...201020623606
gastrointestinal symbionts of chimpanzees in cantanhez national park, guinea-bissau with respect to habitat fragmentation.one of the major factors threatening chimpanzees (pan troglodytes verus) in guinea-bissau is habitat fragmentation. such fragmentation may cause changes in symbiont dynamics resulting in increased susceptibility to infection, changes in host specificity and virulence. we monitored gastrointestinal symbiotic fauna of three chimpanzee subpopulations living within cantanhez national park (cnp) in guinea bissau in the areas with different levels of anthropogenic fragmentation. using standard coprosc ...201323776090
strongyloides infections of humans and great apes in dzanga-sangha protected areas, central african republic and in degraded forest fragments in bulindi, uganda.dna sequence analysis was carried out on strongyloides spp. larvae obtained from fecal samples of local humans, a wild western lowland gorilla (gorilla gorilla gorilla) and a central chimpanzee (pan troglodytes troglodytes) inhabiting dzanga-sangha protected areas (dspa), central african republic, and eastern chimpanzees (pan troglodytes schweinfurthii) living in degraded forest fragments on farmland in bulindi, uganda. from humans, both strongyloides fuelleborni and strongyloides stercoralis we ...201627180094
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
the intestinal parasites of a community of feral chimpanzees, pan troglodytes schweinfurthii.fecal specimens from 32 champanzees living in gombe national park, tanzania, were examined. six species of helminths and 2 species of ciliates were found: probstmayris gombensis file (in press), strongyloides fuelleborni von linstow 1905, necator sp., oesophagostomum sp., abbreviata caucasica von linstow 1902, trichuris sp., troglodytella abrassarti brumpt and joyeux 1921, and an unidentified ciliate. none of the parasitic infections were heavy. this is the first such survey of the chimpanzee in ...1976817011
