Cooperia

Cooperia

(kū-pē'rē-ă),
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. Abbreviated taxonomy: Nematoda, Chromadorea, Rhabditida, Strongylida, Trichostrongyloidea, Cooperiidae

We recovered 23 larvae from the one cultured cattle sample, allowing determination of genera of Strongylida, and identified larvae from genus Haemonchus (n = 17, 73.91% of sample, measure 800-900 [micro]m), Bunostonum (n = 4, 17.39%, 540-620 pm), Cooperia (n = 1, 4.35%, 800 [micro]m), and Trichostrongylus (n = 1, 4.35%).
