Great Basin Naturalist


Thirty-four percent of 100 mink examined from Gallatin and Madison counties, Montana, revealed the presence of Perostrongylus pridhami Anderson, 1962 (Anderson, 1963), in the lungs. This is the first report of P. pridhami in the United States. Thirteen percent of the mink were infected with Taenia mustelae Gmelin, 1790. This is the first report of T. mustelae in southwestern Montana. A checklist of internal parasites of Mustela vison is included.
