The Sclerostomes, also known as Redworms and Palisade Worms, belong to the large group of parasitic bursate nematodes provided with a terminal buccal capsule and armed with one or more fringes of cuticle called “leaf -crowns”. They are found universally in horses and other equines, where they may cause serious diseases. The most important genera, from the standpoint of their prevalence in horses, are Strongylus, Triodontophorus, and Trichonema, the latter being generally known as the Cylicostomes. Other genera of the Family Strongylidae which comprise part of the Sclerostome grouping are Craterostomum, Oesophagodontus, and Gyalocephalus. There are approximately fifty different species of Sclerostomes known to be found in horses and other equines, but up to the present time it has been impossible to distinguish between them from the examination of the eggs alone, Theiler (1923), Taylor (1933), Cornils (1935), Kopirin (1941), and Hummelinck (1946a). Some degree of differentiation has been accomplished by means of the freeliving larvae, Albrecht (1933), Lucker (1936) and (1938), and Hummelinck (1947). The general description that Taylor (1933) gave for the life cycle of Strongylus edentatus may be applied to all of the Sclerostomes and their related groups. “The life cycle in general outline is the same for all species but is identical for none”, Cameron and Parnell (1939). The adult females, found in the colon of the host, lay eggs which reach the ground [...]
