Strongyloides westeri, commonly referred to as intestinal threadworm, is a species of small nematode parasite in the family Strongylidae. Strongyloides (from Greek strongylos, round, + eidos, resemblance) are commonly found in the small intestine of mammals (generally horses and monkeys, specifically foals), that are characterized by an unusual lifecycle (Larvae II, III) that involves one generations of free-living adult worms.
They preferably infest foals, in which they cause diarrhea and dermatitis.
