During the course of a survey of intestinal parasites among the inhabitants of villages along the Fly River in the Kiunga region of Papua New Guinea, eggs of a Strongyloides species were found in the feces of several persons. In subsequent studies, 93 (17.8%) of 520 persons examined from five villages were found to be infected with this parasite. The examination of parasitic and free-living stages of the worm revealed that it is very similar to S. fulleborni, a parasite of monkeys, baboons and apes in Africa and Asia, although a definitive identification could not be made with the material available. Since non-human primates have apparently never inhabitated New Guinea, the origin of these S. fulleborni-like infections is unknown.
