Abstract

Lesions in the heart and lungs resulting from infection by the filarial nematode Cordophilus sagittus were observed in 31 of 42 free-ranging greater kudu (Tragelaphus strepsiceros) of the Kruger National Park, Republic of South Africa. Animals less than 1 yr old were free of lesions whereas many of those over 1 yr old, irrespective of sex, were affected. Adult worms were found free in the right ventricle of the heart, in coronary arteries, and in the pulmonary artery and its branches. In the coronary arteries, worms were usually found coiled within aneurysmal lesions, which were often visible on the epicardial surfaces and occasionally on the endocardial surfaces of the right and left ventricles. Within pulmonary arteries, the presence of the parasites provoked a unique intimal proliferative response similar to that seen in canine dirofilariasis.
