==Description==
Cyathostomins are also known as small strongyles, and are one of the most important gastro-intestinal parasites of the horse. Over 40 species and several genera have been identified. The small, thread-like worms inhabit the caecum and the large colon with their developmental stages confined to the mucosa of the large intestine. Unlike the large strongyles, they do not undergo any extra-intestinal migration during development. Larvae ingested may develop to the L4 stage without interruption, however some larvae may become arrested at the EL3 stage. It is the mass reemergence of these hypobiotic larvae that leads to the clinical disease of larval cyathostomosis.
