Studies On The Helminth Fauna Of Alaska. Xliii. Strigea Macropharynx Sp. N., A Trematode Parasite Of Falco Rusticolus L., Georges Dubois, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Strigea macropharynx sp. n. (Trematoda : Strigeata, Strigeidae), an intestinal parasite of Falco rusticolus L., is described. Falconiformes harbor two species of Strigea (S. falconis Szidat, 1928, and S. macroconophora,/i> Dubois and Rausch, 1950) with vitellaria terminating near the copulatory bursa. Both differ from the new species in having a pharynx that is smaller than or subequal to the buccal sucker, as well as in other details. In S. elegans Chandler and Rausch, 1947, a parasite of Strigiformes, the eggs are larger, the testes of different form, and the vitellaria extend significantly farther into the region of the copulatory …

The Coccidian Parasites (Protozoa, Sporozoa) Of Rodents, Norman D. Levine, Virginia Ivens
Harold W. Manter Laboratory of Parasitology: Library Materials
This monograph summarizes the known information on taxonomy, morphology, life cycle, hosts, location in the host, pathogenicity, geographic distribution, and cross-transmission studies of the 196 named species of coccidia of rodents. These include 176 species of Eimeria, 9 of Isospora, 3 of Wenyonella, 2 each of Cryptosporidium and Klossiella, and 1 each of Dorisiella, Caryospora, Tyzzeria, and Klossia. In addition, similar data are given for those forms for which insufficient information is available to justify assigning them names.
Eimeria, which is the most common genus, has been described from only 15% …

Kowalewskiella Totani N. Sp. (Cestoda: Dilepididae) From Totanus Flavipes, J. Teague Self, John J. Janovy Jr.
John J. Janovy, Jr. Publications
Totanus flavipes (Gmelin) 1789 (lesser yellowlegs) collected from the Cheyenne Bottoms Waterfowl Management area, Barton County, Kansas was parasitized by cestodes belonging to the poorly known genus Kowalewskiella Baczynska 1914 and constituting a species new to science.
Kowalewskiella totani n. sp. is described from Totanus flavipes from Barton County, Kansas. It differs from K. cingulifera (Krabbe 1869) Sandeman 1959 in being much larger and having roughly twice as many testes as the latter species.
Cytogenetic Evidence For The Specific Distinction Of An Alaskan Marmot, Marmota Broweri Hall And Gilmore (Mammalia: Sciuridae), Robert L. Rausch, Virginia R. Rausch
Cytogenetic Evidence For The Specific Distinction Of An Alaskan Marmot, Marmota Broweri Hall And Gilmore (Mammalia: Sciuridae), Robert L. Rausch, Virginia R. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cytogenetic studies based upon somatic cells (bone marrow) have disclosed that the marmot hitherto designated Marmota caligata broweri Hall and Gilmore, occurring in the Brooks Range of Arctic Alaska, differs from M. c. caligata (Eschscholtz) in number of chromosomes (2n=36 as compared with 2n=42 in M. caligata) and in proportions of chromosomal types. Typical karyograms for the two species are presented. It is concluded that the Brooks Range marmot is specifically distinct from M. caligata, the applicable name being Marmota broweri Hall and Gilmore. Also determined were diploid chromosome numbers for two other Nearctic species of marmots, M. …

Studies On The Helminth Fauna Of Alaska. Xlii. Aploparaksis Turdi Sp. N., A Hymenolepidid Cestode From Thrushes, Francis S.L. Williamson, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Aploparaksis turdi sp. n. (Cestoda: Hymenolepididae) is described from the robin, Turdus migratorius L., and recorded also from the varied thrush, Ixoreus naevius (Gmelin), from Iliamna Lake, upper Alaska Peninsula. This cestode is distinguished from the three previously known species of Aploparaksis s. l. occurring in passeriform birds by the size and number of rostellar hooks and by the arrangement and proportions of the genital organs. It is concluded that the validity of the genus Monorcholepis Oshmarin, 1961, to which certain of these species have been assigned, is questionable, and the latter genus is considered to be a synonym of …

Summary
The development of Nuttallia tadzhikistanica in the larvae and nymphs of Hyalomma anatolicum was followed. In the first hours after the larvae had begun blood sucking on infected specimens of Meriones erythrourus, Nuttallia which had got into the intestire of the tick, leave erythrocytes and multiply by division into two or four individuals. Two or four hours later, mono-nuclear trophozoites occur in the haemocoel of the tick. Here their multiple division occurs. Multinucleated developmental stages of Nuttallia occur in the haemocoel during 24 hours after the larvae become detached from the host. The multinucleated stages break down into …

Life Cycle And Development Of Prosthorhynchus Formosus (Van Cleave, 1918) Travassos, 1926, An Acanthocephalan Parasite Of Birds, Gerald D. Schmidt, O. Wilford Olsen
Harold W. Manter Laboratory of Parasitology: Faculty Publications
The life cycle of Prosthorhynchus formosus (Van Cleave, 1918) Travassos, 1926 is presented. The terrestrial isopods Armadillidium vulgare, Porcellio laevis, and P. scaber served as experimental intermediate hosts, and chickens and turkeys as experimental definitive hosts. After ingestion of the eggs by the isopod, the acanthor emerges from its shells within 15 minutes to 2 hours, enters the gut wall of its host, and remains there 15 to 25 days. It then migrates to the hemocoel and develops through the acanthella stage to the infective cystacanth by the 60th to 65th day of infection.

Studies On The Helminth Fauna Of Alaska. Xli. Observations On Cestodes Of The Genus Diplogonoporus Lönnberg, 1892 (Diphyllobothriidae), Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
The study of a collection of cestodes assigned to the genus Diplogonoporus Lönnberg, 1892 disclosed but two species, D. balaenopterae Lönnberg, 1892, and D. tetrapterus (von Siebold, 1848) (provis.). These cestodes occur characteristically in marine mammals but occasionally are found in terrestrial hosts; D. balaenopterae is recorded for the first time from the domestic dog, and it is concluded that D. grandis (Blanchard, 1894), from man, is conspecific with D. balaenopterae. The latter species is recorded for the first time from the humpback whale, Megaptera novaeangliae (Borowski). The relatively small D. tetrapterus, a common parasite of the Steller …
The Specific Status Of The Narrow-Skulled Vole (Subgenus Stenocranius Kashchenko) In North America, Robert L. Rausch
The Specific Status Of The Narrow-Skulled Vole (Subgenus Stenocranius Kashchenko) In North America, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
On morphological and zoogeographical grounds, discussed in the present paper, it is concluded that the narrow-skulled vole in North America, previously designated Microtus (Stenocranius) miurus Osgood, is conspecific with the Eurasian M. (Stenocranius) gregalis Pallas. Fourteen subspecies in Eurasia and 5 in North America are now recognized, but it is probable that the number in Eurasia will be reduced through future investigation. The Eurasian subspecies of this vole comprise two major groups, of which one occupies the tundra zone and the other occurs across central Asia below latitude 60° N; their geographic ranges are largely separate …

Studies On The Helminth Fauna Of Alaska. Xl. Strigea Gruis Sp. N., A Trematode Parasite Of Grus Canadensis (L.), Georges Dubois, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Strigea gruis sp. n. (Trematoda: Strigeata, Strigeidae) is described from the sandhill crane Grus c. canadensis (L.). Only one other species of Strigea (S. neotidis Bisseru, 1956) is known from birds of the order Gruiformes; it is distinguished from S. gruis by several characteristics including its slender form, campanulate anterior segment, size of pharynx and of eggs, position of ovary, and position and size of testes. S. gruis differs from two other species having a relatively large pharynx, S. sphaerula (Rudolphi, 1803) and S. intermedia Szidat, 1932, both parasites of corvids, in the form of the anterior segment and …
The Effect Of Varying Protein Intake On Trichinella Spiralis Infection In Mice, Clare K. Kwan
The Effect Of Varying Protein Intake On Trichinella Spiralis Infection In Mice, Clare K. Kwan
Loma Linda University Electronic Theses, Dissertations & Projects
Three hundred Swiss Webster albino mice three weeks of age were placed on low (8%), medium (24%), high (48%) protein levels and a commercial laboratory animal feed, Purina Chow for various lengths of time: (1) simultaneously with infection, and four weeks thereafter, (2) three weeks before infection and throughout the four-week infection period, and (3) six weeks prior to infection and during the infection period. The protein source was casein. Sixty of the 300 mice used served as noninfected controls, and the other 240 were each infected with 400 washed, suspended Trichinella spiralis larvae obtained from a rat by the …

Arctic Health Research Center, U.S. Public Health Service, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
A program of research in Alaska was initiated by the United States Public Health Service in 1948, with the establishment of a field station in temporary facilities located at Anchorage. This station, officially designated the Arctic Health Research Center in May 1950, was founded largely as the result of surveys of health conditions in Alaska conducted during 1946 and 1947 by two committees representing the American Medical Association. The reports of these committees led Congress to pass a special appropriation bill to support the investigation of health problems in Alaska.
Six research sections were set up within the first year. …

The Seasonal Cycle Of Abundance Of Echinococcus Multilocularis In Naturally Infected Arctic Foxes, Francis H. Fay, Robert L. Rausch
The Seasonal Cycle Of Abundance Of Echinococcus Multilocularis In Naturally Infected Arctic Foxes, Francis H. Fay, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
In some preliminary work on the ecology of Echinococcus multilocularis (Rudolphi, 1801) on St. Lawrence Island, Alaska, Rausch and Schiller (1956. Parasitology, 46 (3 & 4): 395-419) noted that the percentage of arctic foxes, Alopex lagopus Linnaeus, harboring the adult cestodes seemed to vary annually in direct relation to the population density of tundra voles, Microtus oeconomus innuitus Merriam, the principal intermediate host. With the primary objective of examining this relationship in greater detail, an intensive, long-term ecologic investigation was begun on this island in 1955. Some of the results in the first 7 years are reported here.
A Review Of The Genus Echinococcus Rudolphi, 1801, Robert L. Rausch, George S. Nelson
A Review Of The Genus Echinococcus Rudolphi, 1801, Robert L. Rausch, George S. Nelson
Harold W. Manter Laboratory of Parasitology: Faculty Publications
1. The genus Echinococcus Rudolphi, 1801, is reviewed. The recorded measurements of all species are shown in tables, and their taxonomic status is discussed.
2. Three species of Echinococcus can be distinguished by morphological criteria and are considered valid: E. granulosus, E. multilocularis and E. oligarthrus. The status of E. felidis and E. patagonicus is uncertain, but both may be conspecific with E. granulosus. Six species are considered synonyms of E. granulosus: E. cameroni, E. intermedius, E. longimanubrius, E. lycaontis, E. minimus and E. ortleppi.

Echinococcus Infections In Man And Animals In Kenya, George S. Nelson, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
1. Hydatid cysts are found in more than 30 per cent of all cattle, sheep and goats in Kenya, but the disease is prevalent in man only in the semi-desert area of Turkana. Up to the time of the present investigation the life-cycle of the parasite in East Africa had not been studied, but it was suggested that wild carnivores, such as hyenas and jackals, might be the main hosts of the adult worms.
2. One hundred and forty-three carnivores, representing 23 species, have been examined. Echinococcus adults were found in 27 out of 43 domestic dogs (Canis familiaris …

Arhythmorhynchus Capellae Sp. N. (Polymorphidae: Acanthocephala), A Parasite Of The Common Snipe Capella Gallinago Delicata, Gerald D. Schmidt
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Arhythmorhynchus capellae sp. n. is described. The description is based on seven males and seven females from the Common Snipe in northern Colorado. The species is contrasted with two similar species, A. comptus Van Cleave and Rausch, 1950 and A. eroliae (Yamaguti, 1939) Van Cleave and Rausch, 1950. It differs from the former in having 14 proboscis hooks per row rather than eight or nine, and from the latter in having no bursal rays and 16 rows of 14 hooks rather than 18 rows of 12 to 13 hooks.

Alveolar Hydatid Disease Of The Liver: Rationale And Technics Of Surgical Treatment, John T. West, F. J. Hillman, Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Cestodes of the genus Echinococcus cause two distinct diseases: the well-known cystic hydatid disease found in stock-raising areas, caused by E. granulosus, and the more rare alveolar hydatid disease, which is limited to the northern hemisphere and is caused by the biologically and morphologically distinct E. multilocularis.
Eight cases of alveolar hydatid disease of the liver are reported from Alaska, including three patients who underwent hemihepatectomy for advanced lesions. Radical resection is concluded to be the only rational treatment for this otherwise progressive and fatal disease.

Comparative Morphology In Nemic Phylogeny, Armand R. Maggenti
Comparative Morphology In Nemic Phylogeny, Armand R. Maggenti
Harold W. Manter Laboratory of Parasitology: Faculty Publications
In 1945 Simpson wrote: "Phylogeny cannot be observed. It is necessarily an inference from observations that bear on it, sometimes rather distantly, and that can usually be interpreted in more than one way." Certainly this applies to a study of nemic phylogeny where our reasoning is based upon degree of resemblance and subject to confusion by convergence and reversal. Many feel that, because fossil records are lacking, it is of little purpose to indulge in speculation on nemic phylogeny. Nemic taxonomy, however, requires such speculation when it is based upon comparative morphology. Our attempts in taxonomy are really an effort …

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes
United States Naval Medical Research Unit 3: Publications
Over the past several years a large number of references from the USSR, Eastern Europe, and China have been collected dealing with arthropods of medical importance. These references were coded on keysort cards which made it possible to index as many as fifteen subject areas on one card. The usefulness of this indexing system was evident by the number of medical entomologists who used it in searching for references in their specialty. In response to requests from workers in the United States and other countries who did not have ready access to the index. it was decided to publish these …
