With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments. Females are 3–6 mm (0. There is in fact no helminth classification; it is an "artificial" term. Helminth control in horses has been based on the administration of broad-spectrum anthelmintics for over 50 years, but although this has reduced clinical disease, anthelmintic-resistant populations of nematodes (for example, cyathostomins and Parascaris equorum ) have developed due to frequent ‘blanket’ treatments.
