STRONGYLOIDEA
The cat is host to only a single representative genus of the Strongyloidea. This genus is Mammomonogamus which is an unusual representative of this group in that the adult worms tend to be parasites of the airways rather than of the large bowel as is typical of the strongyles found in horses and ruminants. These parasites have a large buccal capsule but lack the corona radiata or leaf crown that is so typical of most of the members of this superfamily. The genus Mammomonogamus appears to be most closely related to parasites of birds, i.e., Syngamus, Boydinema, and Cyathostoma, and to a form that is found in rodents, Rodentogamus.
