<unk>  is a human pathogenic parasitic roundworm causing the disease strongyloidiasis. Its common name in the US is threadworm. In the UK and Australia, however, the term threadworm can also refer to nematodes of the genus Enterobius, otherwise known as pinworms. The<unk>  nematode can parasitize humans. The adult parasitic stage lives in tunnels in the mucosa of the small intestine. The genus<unk>  contains 53 species, and S.<unk>  is the type species. S.<unk>  has been reported in other mammals, including cats and dogs. However, it seems that the species in dogs is typically not S.<unk> , but the related species S. canis. Non-human primates are more commonly infected with S. fuelleborni and S. cebus, although S.<unk>  has been reported in captive primates. Other species of<unk>  that are naturally parasitic in humans, but with restricted distributions, are S. fuelleborni in central Africa and S. kellyi in Papua New Guinea.
