Eighty-two bats comprising the genera Eptesicus, Lasionycteris, Lasiurus, Myotis, and Plecotus collected in British Columbia were examined for the presence of gastrointestinal parasites. Helminths from 24 specimens of Eptesicus fuscus, 11 of Lasionycteris noctivagans, 1 of Lasiurus cinereus, 7 of Myotis californicus, 31 of M. lucifugus, and 3 of M. volans longicrus are listed. Some aspects of the parasitism encountered are discussed.
Intestinal contents from two muskoxen, Ovibos moschatus (Zimmermann), collected in March 1978 on Devon Island, N.W.T., both contained Marshallagia marshalli (Ransom 1906) and Nematodirus helvetianus May 1920. Intestinal contents from five muskoxen collected in August 1978 on Ellesmere Island, N.W. T., contained Moniezia expansa (Rudolphi 1810) (one of the five), Ostertagia trifurcata Ransom 1907 (one of five), M. marshalli (one of five) and N. helvetianus (two of five). Cysticerci of Taenia hydatigena Pallas 1766 were found in two of the five animals from Ellesmere Island.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
