Increase In Size Of Eimeria Separata Oocysts During Patency, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examinations of 18 consecutive fecal samples collected at 6-hr intervals from infected rats showed that oocysts increased in length and width by approximately 40% from the beginning to the end of the patent period. Unsporulated oocysts were first observed in the 3rd fecal collection, 84 to 90 hr post-inoculation (PI) and 100 of these measured 9.9 to 14.3 by 8.8 to 12.1 μ (mean 11.7 by 10.1). Patency ended with the 15th fecal collection, 156 to 162 hr PI, and 100 unsporulated oocysts from this sample measured 14.3 to 17.6 by 13.2 to 15.4 μ (mean 16.3 by 14.2). Despite …

A Syncoeliid (Hemiuroidea Faust, 1929) Metacercaria On A Copepod From The Atlantic Equatorial Current, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The complete life cycle for a species of Syncoeliidae Odhner, 1927, is unknown. Adults are known from the branchial cavity and mouth of marine fishes which are usually found offshore, and second intermediate hosts have been reported. Sars (1885, Challenger Rept. Zool. 13: 228 p.) described the metacercaria of Syncoelium filiferum from the perivisceral cavity of the euphausiids Nematoscelis megalops Sars, 1883, and Thysanoessa gregaria Sars, 1883, in the South Atlantic. DoIlfus (1966, Bull. Mus. Natl. Hist. Nat. Ser. 2 38: 195-200) described Metacercaria (Gen. ?) theomonodi from some poorly preserved material amidst a collection of "copepods and chaetognaths" collected …

Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The literature on diseases and parasites of marine animals has been accumulating at an accelerating rate in recent decades, and at a seemingly geometrical rate in the past few years. Reviews of selected aspects of the subject have appeared (Cheng, 1967; Sindermann, 1966; Sindermann and Rosenfield, 1967). References listed in these papers include a significant, but still a small part, of the available literature. With the proliferation of journals in many languages throughout the world, a complete bibliography, even in a narrow area of research, is almost an impossibility. Then too, the daily appearance of new published information represents an …

Studies On The Helminth Fauna Of Alaska. Xlv. Schistotaenia Srivastavai N. Sp. (Cestoda: Amabiliidae) From The Red-Necked Grebe, Podiceps Grisegena (Boddaert), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The genus Schistotaenia Cohn, 1900, at present includes six species, all parasites of grebes (Podicipediformes). Among helminths found in a red-necked grebe, Podiceps grisegena (Boddaert), on October 18, 1966, at Anchorage, Alaska, were cestodes representing two species of Schistotaenia, of which one is described here as new. The host was an adult bird which evidently had been injured during migration.

This cestode is named in honor of Dr. H. D. Srivastava, in recognition of his significant contributions to helminthological research.

Methods Of Controlling Jackrabbits, James Evans, Paul L. Hegdal, Richard E. Griffith Jr.

Vertebrate Pest Conference Proceedings: 4th (1970)

Since 1963, biologists of the Denver Wildlife Research Center have been investigating methods of alleviating agricultural damage by the black-tailed jackrabbit (Lepus californicus). Of the several approaches to control, most biological methods (predation, habitat manipulation, disease and parasites, and chemosterilants) appear impractical with present knowledge. Mechanical control except for fence barriers, usually has limited effectiveness. Currently, the most useful approach is still chemical control. Improved baiting techniques and several chemical control agents, including an experimental toxicant highly selective for jackrabbits, are described.

Spinitectus Beaveri Sp. N. (Nematoda: Spiruroidea) From The Bonefish, Albula Vulpes (Linnaeus), In Florida, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Spinitectus beaveri sp. n. from the stomach of Albula vulpes is described. In the male, the maximum length is 6 mm, the esophagus is approximately 30% of the body length, the spicule ratio is 1:2.5 to 3.0, and there are 4 pre- and 5 postcloacal papillae. In the female, the maximum length is 7 mm, the esophagus is approximately 27% of the body length, and approximately 38% of the body length is posterior to the vulva. The species most closely resembles S. carolini Holl, 1928, from which it differs by having 10 to 16 rather than 25 to 35 cuticular …

A New Genus Of Trematode (Digenea: Gorgoderidae) From The Ureter Of Tuna Fish (Thunnus Thynnus Maccoyii) In Australia, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

A large, digenetic trematode is described from the ureter of the tuna Thunnus thynnus moccoyii from southern Australian waters. It represents a new genus and species, Cetiotrema crassum (subfamily Gorgoderinae) distinguished by the size and shape of the body, the caeca being distant from the sides of the body, the uterus being intercaecal, the vitellaria arising as three claviform lobes on each side and the seminal vesicle at least partly anterior to the genital pore.

The genus is close to Phyllodistomum Braun; P. carangi Manter, 1947, is considered to belong to Cetiotrema; P. lancea Mamaev, 1968 is very similar …

Conclusions

1. Under experimental conditions wild boars are sensitive to toxoplasmosis to a significant degree. In all 6 of the infected animals the disease ended lethally. The characteristic clinical symptom was involvement of the eyes.

2. Spontaneous Toxoplasma antibodies were observed in 36 (34.3%) of 105 boars studied with CFRs.

3. Toxoplasma was found microscopically in smears of kidney, spleen, and brain from 3 boars; the bioprobe method revealed it in the lymph nodes of 10 animals; in these cases the strain isolated was avirulent.

The Terminology And Occurrence Of Certain Structures Of Digenetic Trematodes, With Special Reference To The Hemiuroidea, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A number of terms applied to structures of digenetic trematodes are defined. The hermaphroditic sac of haploporids is distinguished from the sinus sac of hemiurids. The term sinus organ is applied to a cirrus-like organ in the sinus sac of several genera of Dinurinae.

Glomericirrus septemlobus Teixeira de Freitas and Kohn, 1965 is a synonym of Lecithochirium microstomum Chandler, 1935.

Erilepturus africanus Fischthal and Kuntz, 1963 is a synonym of Dinurus gizae Fischthal and Kuntz, 1963.

System Analysis And Nematode Phylogeny, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The purpose here is to suggest a method which will permit understanding of the phylogenetic relationships of contemporary representatives of the phylum Nematoda without fossils. It is not my intent to again offer a phylogeny for the Nematoda. To say that no real benefit or knowledge of phylogeny or evolution is possible without fossils is succumbing to apathy. One cannot deny or ignore that all systems, morphological, biological and chemical manifested in modern forms developed by evolutionary sequence. It is true that with a complete fossil record the rates of evolution and developmental pressures could be accurately evaluated. However, in …

Transferable Drug Resistance Among Enterobacteriaceae Isolated From Cases Of Neonatal Diarrhea In Calves And Piglets, David P. Aden, Norman D. Reed, Norman R. Underdaul, Charles A. Mebus

School of Veterinary and Biomedical Sciences: Faculty Publications

Fecal specimens were collected on 22 different Nebraska ranches and at the Department of Veterinary Science from young calves and pigs with neonatal diarrhea. Enterobacteriaceae isolated from these fecal specimens were screened for resistance to tetracycline, streptomycin, sulfamethizole, kanamycin, chloramphenicol, colistin, nitrofurantoin, and nalidixic acid. Of the 92 strains studied, 57 were resistant to one or more of these antimicrobial agents. Resistant strains were obtained from all herds involved in the study. The two most common resistance patterns were tetracycline streptomycin sulfamethizole (22 of 57) and tetracycline (13 of 57). None of the strains were resistant to chloramphenicol, colistin, nitrofurantoin, …

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

Harold W. Manter Laboratory of Parasitology: Faculty 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 …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

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

Harold W. Manter Laboratory of Parasitology: Faculty 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 …

Transferable Drug Resistance Among Enterobacteriaceae Isolated From Human Urinary Tract Infections, Donna G. Sieckmann, Norman D. Reed, Carl E. Georgi

Papers in Microbiology

Fifteen sulfonamide-resistant cultures isolated from urinary tract infections in eastern Nebraska were screened for transferable drug resistance by three methods. Seven of the 15 resistant cultures could transfer resistance of varying levels to two or more chemotherapeutic agents. Transfer of drug resistance occurred without accompanying transfer of chromosomal traits and required cell to cell contact. In mixed culture, the number of drug-resistant recipients increased exponentially, reaching a plateau 2 hr after mixing. Spontaneous or artificial elimination of resistance was found to be a rare event. In addition, several drug-sensitive isolates from urinary tract infections were shown to be competent recipients …

Calf Diarrhea (Scours): Reproduced With A Virus From A Field Outbreak, C. A. Mebus, N. R. Underdahl, M. B. Rhodes, M. J. Twiehaus

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Neonatal calf diarrhea typical of that seen in field cases was produced in colostrum-deprived calves by inoculating either feces or bacteria-free filtrates via the duodenum, orally, or by a spray (aerosol). Three calves, kept free of E. coli, developed severe diarrhea following inoculation with a bacteria-free filtrate. Intense fluorescence in the epithelium of sections of small intestine from two experimental calves was observed following staining with ftuorescein-labeled gamma globulin produced with viral antigen prepared from the feces of two experimental diarrhetic E. coli-free calves. Fluorescing cells were also present in the feces of experimental and field cases of neonatal …

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 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.

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 …

Zoonotic Diseases In The Changing Arctic, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Compatible with the biotic uniformity of northern regions, the occurrence of certain organisms which cause zoonotic diseases is general throughout the Arctic. In the past, most frequently affected by such diseases have been aboriginal peoples whose way of life involved encroachment upon naturally occurring parasite-host assemblages. Now, as changes take place in socioeconomic conditions in the Arctic, the importance of zoonotic diseases as a cause of morbidity may lessen among such peoples, but on the other hand, more nonaborigines may be affected. Although my remarks relate mainly to Alaska, again the biotic uniformity of the North seems to have its …
