EURASIAN OTTER (DIROFILARIA IMMITIS

Abstract

A mature male and a mature female Dirofilaria immitis were found in the right ventricle of the heart of a naturally infected 2-yr-old male Eurasian otter (Lutra lutra) that had died of severe lung congestion at a zoo in South Korea. Both developing embryos and microfilariae were present in the uterus of the female D. immitis. Although circulating microfilariae were not detected in blood or tissue, the Eurasian otter may serve as a definitive host for D. immitis.
