Now that veterinarians and researchers are beginning to accept the pathological consequences that can be caused by cyathostomes (small strongyles), more and more researchers want to learn to identify them. Fortunately, for those just learning, the reality is that they will probably see fewer than one-third of the 33 species. Additionally, these species are the most prevalent and in the greatest numbers; consequently, they are the most dangerous to equids. Once a person is familiar with these, a rare species will "stick out like a sore thumb." The fact that a species is so different will be noted and its characteristics easily remembered.
