Studies On The Helminth Fauna Of Alaska. Xxxvi. Parasites Of The Wolverine, Gulo Gulo L., With Observations On The Biology Of Taenia Twitchelli Schwartz, 1924, Robert L. Rausch

Natural biotic relationships already had been severely disrupted in the United States by the time significant interest had developed in faunistic helminthology. Some mammalian species, particularly the larger carnivores, had been extirpated or were represented only by scattered individuals in the few remaining wilderness areas. Thus, it is not remarkable that the helminths of such species as the wolverine, Gulo gulo Linnaeus, have been little studied. Fortunately, however, much of arctic and subarctic North America has endured in its primitive state, and here it is still possible to undertake basic biological studies under undisturbed conditions.

Studies On The Helminth Fauna Of Alaska. Xxxiv. The Parasites Of Wolves, Canis Lupus L., Robert L. Rausch, Francis Williamson

It is generally recognized that canine animals comprise an important reservoir of parasites and diseases transmissible to man. These animals, including the domestic dog, have unusual economic importance in arctic and subarctic North America, particularly for the Eskimos and Indians living in more remote regions. These aboriginal peoples continually have close association with canine animals and would appear to be quite vulnerable to infection from this source. That this is true is already evident, although data on morbidity from animal-borne diseases are far from complete. At the present time, at least in Alaska, these people have little ability to lessen …

Studies On The Helminth Fauna Of Alaska. Xxxv. On The Identity Of Certain Cestodes (Taeniidae) From Foxes, Robert L. Rausch

Some species of the genus Taenia Linnaeus, 1758, are morphologically so similar in the adult stage that their separation is very difficult. Complicating this problem is the questionable validity of certain of these species which have been insufficiently characterized. There are two species, however, the adults of which possess well defined morphological difference but which have been repeatedly confused despite their having been adequately described by early investigators. These cestodes, Taenia crassiceps (Zeder, 1800) and T. polyacantha Leuckart, 1856, have for many years been recognized solely by their larval characteristics under the misconception that the adults were indistinguishable.

Notes On The Prevalence Of Hydatid Disease In Alaskan Moose, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

In conjunction with current moose-management studies in south-central Alaska; 124 pairs of lungs of moose (Alces alces) have been collected and examined for the presence of hydatid cysts, the larval stage of the cestode, Echinococcus granulosus. The lungs were collected in the Cook Inlet region between January 1, 1956 and January 1, 1958, mostly from animals accidentally killed by trains or cars.

The presence or absence of the tapeworm cyst was determined by visual inspection, palpation, and finally by sectioning the lungs into slices approximately % in. thick. Hydatid larvae do not always localize in the lungs …
