Haemonchus

(hē-mong'kŭs),
An economically important genus of nematode parasites (family Trichostrongylidae) occurring in the abomasum of ruminants and causing severe anemia, especially in younger or previously unexposed animals. Some significant species are Haemonchus placei (in cattle, sheep, and goats), Haemonchus similis (in cattle and sheep), and Haemonchus contortus, the stomach, barberpole, or twisted wire worm of cattle, sheep, goats, and other ruminants, of which a few cases have been reported from humans; accidental parasite of humans.

Dose confirmation study of a 1% moxidectin nonaqueous injectable formulation against [L.sub.4] larval and adult stages of Dictyocaulus viviparus, Haemonchus placei and Trichostrongylus axei in cattle in Wisconsin.
(2013) revealed that prevalence of Haemonchus placei was 0% in male cattle and 1.44% in female cattle.
Haemonchus contortus was the most prevalent species of helminth followed by Paramphistomum cervi, Oestertagia circumcincta, Fasciola hepatica, Chabertia ovina , Moniezia expansa, Oesophagostomum radiatum, Bunostomum phlebotomum, Haemonchus placei, , M.
Identification of the helminths collected at necropsy revealed that Haemonchus and Cooperia corresponded to 35.1% and 58.3% of the mean parasitic load, respectively, and that Haemonchus placei and Cooperia punctata were the most frequently observed species.
