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 and Staff 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 …

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 and Staff 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 and Staff 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 …

Automatic Solvent Exchanger, D. R. Viglierchio, Armand R. Maggenti

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

A solvent delivery and removal system has been designed and developed such that solvent exchange in biological specimens and tissues can be effected automatically at ambient or above ambient temperatures. The operation may be programmed so that any series of solvents mutually soluble in sequence may be exchanged. For convenience in calibration and flexibility the system may be operated manually.

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

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

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.
