Strongyloidiasis, caused by the nematodes Strongyloides stercoralis and S. fuelleborni, is a neglected tropical disease affecting millions of people in tropical and subtropical areas. Non-human primates (NHPs) are typically natural hosts of S. fuelleborni but this parasite may spread to humans by zoonotic transmission. In this study, the presence of Strongyloides infections in NHPs in Khon Kaen Zoo, Thailand, was tested for using the agar plate culture technique. Three out of nine species of NHPs harbored S. fuelleborni (33.3%). The overall prevalence from three infected species was 45.5% (5 of 11 animals). DNA was amplified from larval stages of S. fuelleborni and a portion of the 18S ribosomal RNA gene was sequenced. These sequences were identical to previously published for S. fuelleborni. The parasitological and molecular data obtained in this study confirmed the presence of S. fuelleborni among captive NHPs (Bornean orangutans, chimpanzees, and red-shanked douc langurs) in Khon Kaen Zoo in Thailand. There is therefore high transmission potential of S. fuelleborni from NHP reservoir hosts to humans and the subsequent development of human strongyloidiasis.
