Cooperia

Cooperia
A genus of small, slender nematodes (family Trichostrongylidae) inhabiting the small intestine, rarely the abomasum, of ruminants; when fresh they are a bright pink color; they produce serious effects only when present in large numbers. In partly immune animals, these worms become enclosed in nodules in the wall of the intestine; they are less pathogenic in sheep and goats than the trichostrongyles Haemonchus, Ostertagia, and Trichostrongylus.
- C. bisonis species that occurs in cattle, sheep, bison, and pronghorn antelopes.
- C. curticei species that occurs in sheep, goats, and wild deer in Europe, although cosmopolitan in distribution.
- C. fieldingi SYN: C. punctata.
- C. oncophora species that occurs in cattle and domestic and wild sheep, but rarely in the horse; although worldwide in distribution, it is most common in the northern U.S. and Canada. SYN: Strongylus radiatus, Strongylus ventricosus.
- C. pectinata species that occurs in cattle, sheep, water buffalo, dromedary camels, and various wild ruminants; it is common in the southern U.S.
- C. punctata species that occurs mainly in cattle, less commonly in sheep, water buffalo, and several wild ruminants; although worldwide in distribution, it is especially widespread in North America and common in Hawaii. SYN: C. fieldingi.
- C. spatulata a species that occurs in cattle and sheep in the southern U.S., Kenya, Australia, and Malaysia.
