The adult parasitic stage lives in tunnels in the mucosa of the small intestine. The genus Strongyloides contains 53 species, and S. stercoralis is the type species. S. stercoralis has been reported in other mammals, including cats and dogs.However, it seems that the species in dogs is typically not S. stercoralis, but the related species S. canis.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.
