dc.description.abstract | Schistosoma kisumuensis n. sp. is described based on 6 adult males and 2 adult females collected from the circulatory system of 3 murid rodent species, Pelomys isseli, Mastomys natalensis, and Dasymys incomtus. Specimens were collected from a single location, Nyabera Swamp, in Kisumu, Kenya in the Lake Victoria Basin. This new species is morphologically similar to members of the S. haematobium group, currently represented by 8 species parasitizing artiodactyls and primates, including humans. Schistosoma kisumuensis differs from these species by producing relatively small Schistosoma intercalatum-like eggs (135.2 x 52.9 microm) with a relatively small length to width ratio (2.55). Comparison of approximately 3000-base-pair sequences of nuclear rDNA (partial 28S) and mtDNA (partial cox1, nad6, 12S) strongly supports the status of S. kisumuensis as a new species and as a sister species of S. intercalatum. The cox1 genetic distance between these two species (6.3%) is comparable to other pairwise comparisons within the S. haematobium group. Separation of the Congo River and Lake Victoria drainage basins is discussed as a possible factor favoring the origin of this species. | en |
