Oesophagostomum spp. are parasitic nematodes of mammals, including humans and other primates. To identify species and determine phylogeny, we analysed DNA sequences of adult and larval Oesophagostomum from wild chimpanzees in Bulindi, Uganda, which inhabit degraded forest fragments amid villages. Oesophagostome larvae and/or eggs from baboons in Tanzania and South Africa and from a Japanese macaque were also sequenced. Based on the internal transcribed spacer 2 (ITS2) of nuclear ribosomal DNA and partial cytochrome c oxidase subunit 1 gene (Cox1) of mtDNA, O. stephanostomum and O. bifurcum were identified from chimpanzees. Bulindi is the second locality where molecular detection of O. bifurcum in wild chimpanzees has been made. While most O. stephanostomum had ITS2 genotypes recorded previously, three new genotypes were detected. Among four ITS2 genotypes of O. bifurcum from chimpanzees, one was identical to that from various monkey species in Kibale, Uganda, and baboons from Tanzania and South Africa; another was shared by a baboon from Tanzania. No genotype was identical with that of the cryptic species reported from humans and monkeys in Kibale. Phylogeny based on Cox1 sequences of O. stephanostomum showed locality-dependent clades, whereas those of O. bifurcum formed clades composed of worms from different hosts and localities. |
