Research Abstract |
Strongyloides spp. were obtained from a variety of wild animals, particularly primates in Japan and Africa. Genetic information such as 18S ribosomal RNA gene (rDNA) and the cox-1 region of mitochondrial DNA (COI) were collected. In this study, particular attention was paid to S. stercoralis and S. fuelleborni which are believed to infect both human beings and non-human primates. We found that four loop regions of the 18S rDNA of Strongyloides spp. are highly variable by species, and useful for species-differentiation. This technique together with genetic analyses of COI disclosed that S. fuelleborni kept by chimpanzees and a human patient working in the same region were identical, suggesting that human beings can be infected by S. fuelleborni maintained by wild non-human primates by chance. Simultaneously, distinct genetic backgrounds of morphologically identical S. fuelleborni distributed from Africa to Far East was indicated.
