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.

Adult horses rarely harbor patent infections, but mares often have larval stages within their tissues that are activated by parturition to move into the mammary tissue and, subsequently, are transmitted to foals in the milk.trongyloides westeri is found in the small intestine in foals.
