Parasitic Organisms In The Blood Of Arvicoline Rodents In Alaska, Francis H. Fay, Robert L. Rausch

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

A Grahamella-like organism (Schizomycetes: Bartonellaceae) was found in erythrocytes of laboratory-reared northern voles, Microtus oeconomus Pallas, which had been inoculated intraperitoneally with a saline suspension of ground fleas, Megabothris abantis (Roths.), from wild northern voles captured at Lower Ugashik Lake, Alaska Peninsula. A live-trapped northern vole from the same locality harbored trypanosomes referable to T. microti (Mastigasida: Trypanosomatidae). Two morphologically similar but biologically different strains of piroplasms (Piroplasmasida: Theileriidae) of uncertain generic status were isolated from northern voles of Ugashik Lake origin and from northern red-backed voles, Clethrionomys rutilus Pallas, from the vicinity of Anchorage, Alaska. In the natural …

Digenetic Trematodes Of Marine Teleost Fishes From Biscayne Bay, Florida, Robin M. Overstreet

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

This study includes 111 species of Digenea from 69 of 113 species of teleost fishes examined from Biscayne Bay, Florida. Biscayne Bay represents the reported northern limit along the Atlantic coast for all but 22 of the 111 species. It represents the southern limit for only one, Didymocystis scomberomori. From the known collections reported in the literature, the Digenea from Biscayne Bay appear to consist primarily of a tropical fauna. Species previously known from the Pacific Ocean only are Botulisaccus pisceus and Pseudocreadium scaphosomum. There are 81 new host records.

Two new genera are created: Claribulla (Felloclistomatidae) and …

Acanthocephala Of Louisiana Picidae With Description Of A New Species Of Mediorhynchus, Brent B. Nickol

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

One hundred eighty-three woodpeckers of eight species collected in Louisiana were examined for Acanthocephala. Only the red-bellied woodpecker, Centurus carolinus, was infected. One of 53 was parasitized by an immature specimen of Mediorhynchus grandis; three by Centrorhynchus spinosus; 12 by Mediorhynchus centurorum sp. n. The new species of Mediorhynchus is distinguished by a trunk which is very narrow in the anterior 3 mm, but is suddenly expanded farther posteriad. Proboscis armature of 22 to 24 slightly spiral rows of six hooks and four or five spines each differs from all other species of the genus except M. …

Studies On The Helminth Fauna Of Alaska, Xlvi. Davainea Lagopodis Sp. Nov. (Cestoda: Davaineidae) From Grouse (Tetraonidae), Robert L. Rausch

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

Cestodes of the genus Davainea Blanchard 1891, from grouse in various Eurasian and North American regions have been identified as D. tetraoensis Fuhrmann 1919, or less frequently as D. proglottina (Davaine 1860). Those from ptarmigan (Lagopus spp.) in Alaska, resembling D. tetraoensis in some details but having only a single row of rostellar hooks and fewer testes, were earlier reported as D. proglottina by Babero (1953). The study of additional material from grouse from Alaska indicates that this cestode is specifically distinct from the two species mentioned. It is described here as new.

Axenic Ovarial Explants From The Marine Nematode Deontostoma Californicum On Culture Media, D. R. Viglierchio, Armand R. Maggenti, R. N. Johnson

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

The gonads of Deontostoma californicum were isolated from the organismal environment by dissection. In an attempt to approximate the in vivo condition and to maintain in vitro architecture and function ten media recommended for the culture of insect cells or organs were tested. The media were prepared in two series: one according to published recommendations and the second substituting filtered seawater for the inorganic salts and distilled water. Media were prepared as both liquid and gel (agar) with and without antibiotics. Whole animals and eggs were placed on the same culture media series as the ovarial explants. Ovarial explant reaction …
