Parasites of the muskrat (Ondatra zibethica) have received considerable study, but little in Ohio. From March 20, 1943, to March 22, 1945, 70 Ohio muskrat carcasses were examined, most of them being obtained from trappers by Merrill C. Gilfillan, Leader of the Pittman-Robertson Muskrat Project in Ohio. The specimens were from seven localities: Lake Erie Marshes (28); Killbuck Valley Marsh (17, lacking liver and lungs); Walnut Creek (19) and Whetstone Creek (2), (Morrow County); Buckeye Lake (1); Little Scioto River, Marion County (1); and Union County near Marysville (2).
