Strongyloides StronÂ·gyÂ·loiÂ·des (strÅn'jÉ-loi'dÄz) n. A genus of small nematode intestinal parasites that includes the species that causes strongyloidiasis in humans.
An unusual feature of S. stercoralis is autoinfection. Only one other species in the Strongyloides genus, S. felis, has this trait. Autoinfection is the development of L1 into small infective larvae in the gut of the host.ence, it is a very rare infection in developed economies. In developing countries, it is less prevalent in urban areas than in rural areas (where sanitation standards are poor). S. stercoralis can be found in areas with tropical and subtropical climates.
