Greek: strongylos = rounded.
Species of the nematode family Strongylidae.
The species of the genus Strongylus ( S. vulgaris, S. equinus, S. edentatus, S. asini) are 1–5 cm long, yellowish-brown roundworms with a buccal capsule (Figs. 1 and 2). They are found worldwide in the caeca and colon of equids. The prepatent periods are long (6.5–11 months), since the larva 3 starts a parental wandering (and rest) after being taken up with the food.
