Distribution And Specificity Of Helminths In Microtine Rodents: Evolutionary Implications, Robert L. Rausch Sep 1957

Distribution And Specificity Of Helminths In Microtine Rodents: Evolutionary Implications, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The taxonomic status of anoplocephaline cestodes of microtine rodents has been reviewed. Of the genus Andrya Railliet, 1883, five species are considered valid: A. macrocephala Douthitt, 1915; A. primordialis Douthitt, 1915; A. montana Kirshenblat, 1941 ; A. arctica Rausch, 1952; A. bairdi Schad, 1954. Of the genus Paranoplocephala Luehe, 1910, six species are regarded as valid: P. omphalodes (Hermann, 1783); P. blanchardi (Moniez, 1891); P. infrequens (Douthitt, 1915); P. variabilis (Douthitt, 1915); P. lemmi Rausch, 1952; P. neofibrinus Rausch, 1952. Andrya caucasica Kirshenblat, 1938, and A. bialowizensis Soltys, 1949, are regarded as synonyms of A. macrocephala. Paranoplocephala brevis Kirshenblat, 1938, …

The Occurrence Of Echinococcus Multilocularis Leuckart, 1863, In Japan, Robert L. Rausch, Jiro Yamashita

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since 1937, when alveolar hydatid disease was first recognized on the Japanese island of Rebun, 25 cases have been investigated clinically. About one percent of the population of the island is believed to be infected. (Yamashita et al., 1955). Five cases also have been reported from other islands, some of these involving emigrants from Rebun (Inukai et al., 1955; Yamashita, 1956).

Studies On The Helminth Fauna Of Alaska. Xxxi. Observations On The Propagation Of The Larval Echinococcus Multilocularis Leuckart, 1863, In Vitro, Robert L. Rausch, Virginia Jentoft

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Larval reproduction in Echinococcus multilocularis Leuckart, 1863, takes place through the proliferation of exogenous secondary vesicles (Rausch, 1954). In some species of host this process appears to be continual, extending over a long period of time with little tendency for self-limitation. Consequently, the growth characteristics of this larval cestode are such that it would seem well suited to culture in vitro.

Studies On The Helminth Fauna Of Alaska. Xxv. The Ecology And Public Health Significance Of Echinococcus Sibiricensis Rausch & Schiller, 1954, On St. Lawrence Island, Robert L. Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The occurrence of a species of Echinococcus (Rudolphi, 1801) on St Lawrence Island was noted by the writers in early 1950. Recognition of its unusual host relationships led to an investigation of the ecology of this cestode, E. sibiricensis Rausch & Schiller, 1954. It is the purpose of this paper to report the results of this work, with emphasis on alveolar hydatid disease in man, of which this cestode is the etiologic agent.


Observations On Shipleya Inermis Fuhrmann, 1908 (Cestoda: Acoleidae), Marietta Voge, Robert L. Rausch Oct 1956

Observations On Shipleya Inermis Fuhrmann, 1908 (Cestoda: Acoleidae), Marietta Voge, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Shipleya inermis, described by Fuhrmann (1908) and redescribed by Baer (1940), is known from only few specimens. The first and only North American record of this species was published by Webster (1951), who reported the finding of two specimens in dowitchers. Examination of a large number of cestodes from dowitchers collected by Rausch, and of cestodes from the Helminthological Collection of the United States National Museum yielded specimens which are without doubt Shipleya inermis. However, some of our observations which are reported here do not agree with Baer's description. In particular, we are unable to agree with Baer …

Studies On The Helminth Fauna Of Alaska. Xxvii. The Occurrence Of Larvae Of Trichinella Spiralis In Alaskan Mammals, Robert L. Rausch, B. B. Babero, Virginia R. Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 1948 much interest in trichinosis in arctic regions was aroused, particularly by the findings of Thorborg et al. (1948), who investigated serious outbreaks occurring among the Eskimo of West Greenland during 1947. Consequently, with the founding of the Arctic Health Research Center in the autumn of 1948, a study of trichinosis in Alaska was the first project to be initiated by the Zoonotic Disease Section (formerly Animal-borne Disease Section) of this Center.

Field work was begun in January, 1949, and a preliminary note on trichinosis in Alaskan mammals was published by Brandly and Rausch (1950). The subject of trichinosis …

Studies On The Helminth Fauna Of Alaska. Xxviii. The Description And Occurrence Of Diphyllobothrium Dalliae N. Sp. (Cestoda), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Plerocercoid larvae of Diphyllobothrium spp. occur commonly in various species of freshwater and anadromous fishes in Alaska. Several times in recent years the writer has observed a distinctive plerocercoid in the blackfish, Dallia pectoralis Bean, an abundant and economically important species in the Kuskokwim River region of western Alaska. This cestode was studied in detail during the summer and fall of 1955, and has been found to represent an undescribed species, for which the name Diphyllobothrium dalliae n. sp. is proposed.

Occurrence And Distribution Of Hymenolepidid Cestodes In Shrews, Marietta Voge, Robert L. Rausch Dec 1955

Occurrence And Distribution Of Hymenolepidid Cestodes In Shrews, Marietta Voge, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A survey of the literature dealing with cestodes of shrews reveals the increasing interest of contemporary parasitologists in this poorly known group of symbionts. In the United States, approximately 18 species have been described from shrews in the last 15 years. These reports deal almost exclusively with morphology of the cestodes; however, information on distribution, host specificity, rate and intensity of infection, is either fragmentary or not available in published form.


A List Of Cestode Parasites From California Mammals, Marietta Voge Oct 1955

A List Of Cestode Parasites From California Mammals, Marietta Voge

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report brings together information on the occurrence and distribution of cestode parasites in California mammals. The original information reported herein, was obtained by students, myself, and other staff members of this university. Although the host-parasite list which follows is far from complete, the dearth of knowledge about the helminth fauna in California seems to justify the publication of relatively few data, in the hope that other workers will be able to use this list as a starting point and add to it.

With few exceptions, the common names of the hosts, as given in the host list, were obtained …


Unusual Pathogenicity Of Diphyllobothrium Sp. In A Black Bear, Robert L. Rausch Jul 1955

Unusual Pathogenicity Of Diphyllobothrium Sp. In A Black Bear, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The black bear, Ursus americanus Pallas, has been found to he an exceptionally good host for a common species of Diphyllobothrium, as evidenced by the large size attained by individual strobilae, and the duration of infections experimentally established. Since 1950, the writer has used at least five of these bears annually in the study of Diphyllobothrium spp. With the single exception reported herein, no adverse effect to the hosts has been recognized.

Cyclustra Ardeae N. Sp. And The Status Of Dendrouterina Fuhrmann, 1912 (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three cestodes representing a species of the genus Cyclustra Fuhrmann, 1901, were obtained by the writer from a great blue heron, Ardea herodias L., collected at Neville, Rock County, Wisconsin, on April 14, 1947. The bird was an adult male, weighing 2,630 grams. Two other great blue herons from this locality were also autopsied, but were negative for this cestode. Two species of Cyclustra are known, bath from ardeiform birds. The Wisconsin material differs from these in morphological details, and is described herein as new.
The cestodes were stained with Semichon's acetic carmine, and mounted entire. The strobila of this …

Studies On The Helminth Fauna Of Alaska. Xxiv. Echinococcus Sibiricensis N. Sp., From St. Lawrence Island, Robert L. Rausch, Everett Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

As the result of field and laboratory investigations extending over a period of more than four years, we have amassed considerable information on the life cycle and ecology of a cestode of the genus Echinococcus (Rudolphi, 1801). Occurring on St. Lawrence Island, which lies in Bering Sea about 40 miles southeast of Cape Chukotskyi, northeast Siberia, this cestode not only has an interesting life cycle, but in the larval stage is an important parasite of humans.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During the summer of 1953, Mr. Edward T. Roche, of the Department of Zoology, University of Southern California, continued observations on the life history of the ground squirrel, Citellus undulatus barrowensis (Merriam), along the Meade River south of Point Barrow, Alaska. In the course of this work, 55 ground squirrels were examined for intestinal parasites, and were found commonly to harbor cestodes. Mr. Roche kindly offered a number of these cestodes to the writer for study, and they represent an undescribed species of Paranoplocephala Liihe, 1910.

In appreciation of the generous cooperation extended to the personnel of this laboratory by …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

According to Eguchi (1934), two species of salmon (Oncorhynchus) serve as a source of human infection by a cestode identified as Diphyllobothrium latum (Linnaeus, 1758), in Japan. The possible role of these fishes in the transmission of cestodes to humans and other animals has not been investigated in North America, nor, apparently, on the Eurasian mainland. However, Ward (1930) reported unidentified Diphyllobothrium-like plerocercoids from Alaskan salmon; Simms and Shaw (1931) collected plerocercoids identified as D. cordiceps (Leidy, 1871) from Oncorhynchus kisutch (Walbaum) from lakes in Oregon; and Wardle (1932) reported plerocercoids of Diphyllobothrium spp. from O. kisutch …

Studies On The Helminth Fauna Of Alaska. Xx. The Histogenesis Of The Alveolar Larva Of Echinococcus Species, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The occurrence of the larval stage of Echinococcus granulosus (Batsch, 1786) in a microtine rodent, Clethrionomys rutilus Pallas, on Bering Island was reported by Barabash-Nikiforov (1938) and Afanas'ev (1941). Rausch and Schiller (1951) reported this cestode from tundra voles, Microtus oeconomus Pallas, collected on St. Lawrence Island. Further observations have shown that it occurs also in C. rutilus in the same location. Both species of rodents have a wide circumboreal distribution.

The Taxonomic Value And Variability Of Certain Structures In The Cestode Genus Echinococcus (Rudolphi, 1801) And A Review Of Recognized Species, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Although cestodes of the genus Echinococcus have been much studied in the past, there is need for an evaluation of these morphological characters used as the basis for species differentiation. The generous cooperation of other investigators in providing necessary foreign material and the results of nearly five years of field work in Alaska make possible such a study. It is the purpose of the paper to evaluate morphological characters used at the species level to differentiate these cestodes, and to review the status of species currently considered valid.


On The Status Of Some Arctic Mammals, Robert L. Rausch Jul 1953

On The Status Of Some Arctic Mammals, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The mammal fauna of arctic Alaska is comprised of about thirty species, most of which are widely distributed. A few of these are essentially nearctic species, having extended their range northwestward during post-Pleistocene time. The majority, however, consists of forms which are either circumboreal in their distribution, or which have closely-related palearctic counterparts-considered specifically distinct hy most North American mammalogists. Sorne of the foremost Old World workers, however, do not agree that Bering Strait constitutes a barrier which effectively separates the Old World fauna from the New.

Studies On The Helminth Fauna Of Alaska. Xiii. Disease In The Sea Otter, With Special Reference To Helminth Parasites, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During the spring of 1951, the U. S. Fish and Wildlife Service undertook the removal of sea otter, Enhydra lutris (L)., from the Aleutian Island of Amchitka, for the purpose of restocking range from which the animals have long been exterminated. The decision to undertake this activity was influenced by the nature of military operations planned for the island later the same year. The capture and removal of the otter were under the supervision of Mr. Robert D. Jones, Biologist, U. S. Fish and Wildlife Service. Heavy losses among the animals shortly after capture made the venture unsuccessful. Many deaths …
