Schistosomatium douthitti (Cort, 1914) Price, 1929 in a porcupine (Erethizon dorsatum) in eastern Ontario, Canada

Abstract

Schistosomatium douthitti (Cort, 1914) Price, 1929 was found in the portal system of a new host, the porcupine, Erethizon dorsatum (L.), from eastern Ontario. Histological examination of the conspicuously mottled liver revealed eggs of the parasite throughout the parenchyma. Many of the eggs had induced extensive granulomatous inflammatory reactions with necrosis of adjacent hepatic cells.
