Ultrastructure Of Sarcocystis Sporocysts From Passerine Birds And Opossums: Comments On Classification Of The Genus Isospora, Edith D. Box, Alan A. Marchiondo, Donald W. Duszynski, C. Patrick Davis

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sporocysts were obtained from the feces of opossums (Didelphis virginiana) which had been fed muscles of passerine birds (Molothrus ater and Cassidix mexicanus) infected with Sarcocystis. Sporocysts were examined by phase microscopy and scanning and transmission electron microscopy. Ridges on the surface of the sporocysts outlined four plates. Thin sections of the sporocyst wall showed thickened regions and gaps interpreted as cross sections of the ridges. The sporocyst wall has four major layers with a thick, granular inner layer which resembles the inner layer of sporocysts of related species. Excystation structures are discussed as a …

Parasite Population Regulation: Lethal And Sublethal Effects Of Leptorhynchoides Thecatus (Acanthocephala: Rhadinorhynchidae) On Hyalella Azteca (Amphipoda), Richard L. Uznanski, Brent B. Nickol

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The hypothesis that Leptorhynchoides thecatus populations are regulated by mortality of heavily infected intermediate hosts, Hyalella azteca, was examined experimentally. Mortality related to the infection process could not be demonstrated because no survivorship difference occurred between amphipod groups exposed to L. thecatus and unexposed control groups after 24 hours Likewise, amphipod mortality could not be associated with infection intensity during this period. Amphipod mortality, growth, and infection intensity were monitored for 25 days after a 24-hour exposure period. Cystacanths were infective to fish after 25 days. Survivorship of exposed amphipods was at least as great as that of unexposed …

Isospora californica (Protozoa: Eimeriidae) in Peromyscus maniculatus (Cricetidae) from White Sands National Monument, New Mexico

This report constitutes a new geographic record for Isospora californica and adds a micrograph of the coccidium, which the original description did not include. The latter is important because to correctly identify coccidia, a photograph as well as a drawing is at times necessary.

Stress: What Is It And How Can It Be Quantified?, T. H. Friend

Sentience Collection

An animal may be considered to be in a state of stress if abnormal behavior or extreme adjustments in its behavior or physiology are necessary in order to cope with adverse aspects of its environment. Methods used to determine if an animal is stressed can be either behavioral or physiological. Behavioral methods may be highly erroneous due to their subjective nature since alterations in behavior do not necessarily prove that an animal is stressed. There is no single measure of stress that can be used in all situations at this time. Every measure must be critically evaluated to ensure that …

An Examination Of The Red Blood Cell Alloantigentic System In The Chinese Hamster, Kathryn Elliget Blashfield

Masters Theses

This research was done to determine whether any ABH-like blood group system was present in Chinese hamsters (Cricetulus griseus). The population of animals included 35 hamsters, 20 "normal" or outbred (10 males; 10 females) and 15 diabetic from The Upjohn Company's colony of inbred diabetic animals (8 males; 7 females; BE and BA lines). Animal sera and erythrocytes were compared by: hyperimmunization of rabbits (10 New Zealand White) with hamster erythrocytes; screening hamster erythrocytes and plasmas with human blood diagnostic typing antisera (Ortho Diagnostics), anti-H lectin, anti-A₁ lectin and human red cells of various types; absorption and elution of …

Three Proteocephalid Cestodes From Colombian Siluriform Fishes, Including Nomimoscolex Alovarius Sp.N. (Monticelliidae: Z Ygobothriinae), Daniel R. Brooks, Thomas L. Deardorff

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three species of proteocephalid cestodes were collected from Colombian siluriform fishes. Goezeella siluri Fuhrmann, 1916 is reported from Ageneiosus caucanus for the first time, and Colombia is a new locality. Goezeella siluri has a metascolex, biloculate suckers, and cortical gonads. Proteocephalideans possessing uniloculate suckers and cortical gonads represent two groupings. Those species possessing metascolices represent the genus Spatulifer Woodland, 1934, containing the species surubim, piramutab, piracatinga , rugosa , and rugata. Those lacking metascolices belong in Monticellia LaRue, 1911, comprising coryphicephala, lenha, megacephala, and spinulifera. New combinations include Spatulifer piramutab for Goezeella piramutab, S. piracatinga for Monticellia piracatinga, …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three new species of Goezia from fishes in North America are described and supplemental data for G. minuta and several unidentified adults and larvae are presented. Males, especially their caudal papillae, are necessary to identify most species. For the new species, G. pelagia sp. n. from Rachycentron canadum and Chaetodipterus faber in the northern Gulf of Mexico possesses 12- 19 preanal, two para-anal, and four postanal pairs of papillae; G. kliksi sp. n. from Pogonias cromis in Lake Borgne, Louisiana, has 10-16 preanal, two para-anal, and five postanal pairs of papillae, and G. sinamora sp. n. from Tilapia aurea, …

Redescription Of Diandrya Composita Darrah, 1930 (Cestoda: Anoplocephalidae) From Nearctic Marmots (Rodentia: Sciuridae) And The Relationships Of The Genus Diandrya Emend., Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

According to the original description of Diandrya composita Darrah, 1930 (the type and only species of the Nearctic genus Diandrya Darrah, 1930) , this cestode would possess a combination of organs, the "interproglottidal glands" and "pedunculated prostate glands," otherwise unknown in any member of the Anoplocephalidae. Neither of these organs is present in D. composita . This species is redescribed and the generic diagnosis is emended accordingly. Diandrya composita has its closest affinities with cestodes of the genus Andrya Railliet, 1893, from which it differs significantly only in reduplication of the reproductive organs.

Two New Species Of Cestode (Trypanorhyncha, Eutetrarhynchidae) From The Yellow-Spotted Stingray, Urolophus Jamaicensis, Kinga J. Kovacs, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eutetrarhynchus thalassius sp.n. and Eutetrarhynchus caribbensis sp.n. were collected from the spiral valves of three yellow-spotted stingrays, Urolophus jamaicensis, in Discovery Bay, Jamaica. Both species most closely resemble Eutetrarhynchus geraschmidti Dollfus, 1974. Eutetrarhynchus thalassius differs from E. geraschmidti in the arrangement, sizes, and shapes of tentacular armature, Eutetrarhynchus caribbensis differs from E. geraschmidti and E. thalassius on the basis of metabasal armature. The tentacular armature of E. geraschmidti is redescribed,

Cestode Parasites Of Some Venezuelan Stingrays, Monte A. Mayes, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Forty-seven stingrays representing 8 species collected in Venezuelan coastal waters were examined for cestode parasites. Specimens of 18 tetraphyllidean, lecanicephalidean, and trypanorhynchan cestode species were collected, 3 described as new. Rhinebothrium margaritense sp. n. from Dasyatis guttata and D. americana most closely resembles R. spinicephalum and R. tetralobatum but differs by having 3-6 rather than only 2 testes per proglottid and a different number of bothridial loculi. Rhodobothrium paucitesticulare sp. n. from Rhinoptera bonasus possesses fewer than half as many testes per proglottid as any other known member of the genus. Dioecotaenia campbelli sp. n. differs from D. cancellata by …

Epicharinema Keralense N. Gen, N. Sp., And Comments On Atylenchinae And Ecphyadophorinae (Nemata : Tylenchidae), Dewey J. Raski, Armand R. Maggenti, Puthenkandathil K. Koshy, Varghese K. Sosamma

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Epicharinema keralense n. gen., n. sp. is described from nematodes collected from soil about the roots of coconut palm in Kerala, India. This genus is related to Ecphyadophora and Ecphyadophoroides but differs from both by virtue of its greater length; larger stylet, spicules and gubernaculum; and its well-developed metacorpus with a prominent valve. E. keralense n. gen., n. sp. also has an elongate, sinuous cleft connected to the amphid which, with the valve in its metacorpus, indicates these belong to the family Tylenchidae. Relationship with Atylenchus and Eutylenchus is also considered and comments on the subfamilies Atylenchinae and Ecphyadophorinae are …

Diatoms In The Gills Of The Commercial White Shrimp, Robin M. Overstreet, Susan Safford

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A white shrimp from Galveston, Texas, is the first reported case of a crustacean internally infected by a diatom. Even though more than one species occurred in debris on and between gill filaments, only individuals of Amphora sp. occurred within gills. To determine if a related diatom would easily reproduce within the shrimp and cause. a host response similar to that observed, we injected cultured specimens of A. coffaeformis into white shrimp. Under the experimental conditions, individuals of that species did not divide, but they elicited an extensive melanistic host-response.

Cephalic Papillae Of Giant Kidney Nematode Dioctophyma Renale (Goeze, 1782) And Comparison With Eustrongylides Spp., J. R. Lichtenfels, P. A. Madden

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cephalic papillae of third- and fifth-stage Dioctophyma renale and fourth- and fifth-stage Eustrongylides spp. were found to be of three kinds in addition to the amphids. In all the stages of both genera studied, six papillae were in an internal circle, six in an external circle, and eight to 10 in two lateral fields of four or five each between the internal and external circles. Amphids were closely associated with the externolateral papillae. Another porelike papilla was found between the ventroventral papillae in all but fifth-stage D. renale. In third-stage D. renale, lateral rows of somatic papillae were …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oocysts and sporocysts of Eimeria funduli sp. n. are described from the Gulf killifish, Fundulus grandis, on the basis of light microscopy, transmission and scanning electron microscopy, and location in the liver of infected hosts. The spherical sporulated oocysts of E. funduli isolated from liver tissue measure 20-31(25) μm across with ovoid sporocysts 9-11 × 5-7 (10 × 6) μm. A micropyle, polar granule, and oocyst residuum are absent, but sporocysts have Stieda and substieda bodies, a few residual granules, and 10-25 (15) unique projecting structures with expanded distal portions that we term “sporopodia.” Sporopodia 1-3 (2) μm high …

The Development Of Techniques For The Enumeration Of Selected Pathogenic Bacteria In Lynnhaven Estuarine Sediments, Mark T. Frank

Biological Sciences Theses & Dissertations

Methodologies for the improved recovery of selected pathogenic bacteria from estuarine sediments were investigated. Laboratory and field studies were conducted to document the sensitivity of the techniques for isolating Salmonella species, Pseudomonas aeruginosa, and Vibrio parahaemolyticus. Vibrio parahaemolyticus-like organisms were enriched in a seawater yeast extract broth and isolated from Thiosulfate Citrate Bile Salts Sucrose plated media. Enrichment procedures with and without elevated temperatures and subsequent transfers to selective and differential plated media have been examined for the isolation of Salmonella species and P. aeruginosa. These pathogens were initially assayed for utilizing primary enrichments of asparagine …

Agar Plate Culture Of Selected Trypanosomatidae, Amy Doran Keppel

School of Biological Sciences: Dissertations, Theses, and Student Research

Summary

The study of trypanosomatid biology would benefit greatly from the acquisition of a tool for culturing such as those used in microbiology. Agar plate culture has been described several times, but until the present its potential for use in this area has been underestimated. The previous work has demonstrated that this culture method may be used to culture a wide variety of species, that these species give rise to identifiable colony phenotypes, and that these are stable regardless of the life cycle stage used to initiate the culture. It was also shown that colonies could be initiated from the …

Detection Of Unique Tumor-Associated Proteins In The Urine Of Patients With Transitional Cell Carcinoma By High Resolution Two-Dimensional Polyacrylamide Gel Electrophoresis, Robert David Lehman

Biological Sciences Theses & Dissertations

A two-dimensional polyacrylamide gel electrophoretic technique was developed for the detection of unique tumor-associated proteins in urine of patients with transitional cell carcinoma (TCC) of the urinary bladder. This technique yielded high resolution of polypeptides in the urine of cancer patients. Urine was chosen as a source of tumor-associated components because the location of the tum or should release already solublized tum or substances in to the urine.

Urinary proteins were concentrated and then analyzed by the two - dimensional electrophoretic technique using isoelectric focusing in the first dimension and sodium dodecylsulfate - polyacrylamide gel electrophoresis in the second dimension. …
