heartworm

Di·ro·fi·la·ri·a im·'mi·tis

a species of filarial worms; primary hosts are dogs and other canids in tropical, subtropical and temperate climates, adult worms are found chiefly in the right ventricle and pulmonary arteries of dogs; sometimes a serious pathogen of racing and show dogs, especially in the southern U.S. where mosquito vectors are most common; Dirofilaria immitis and its canine host have been used to test chemotherapeutic agents, and an extract of Dirofilaria immitis may be used as a nonspecific intradermal antigen in the diagnosis of human filariasis and in complement-fixation tests.
