Rhizonema Sequoiae N. Gen. N. Sp. From Coast Redwood Sequoia Sempervirens (D. Don) Endl., I. Cid Del Prado Vera, B. F. Lownsbery, Armand R. Maggenti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Rhizonema sequoiae n. gen. n. sp. is described from the roots of Coast Redwood, Sequoia sempervirens (D. Don) Endl., growing near Lake Lagunitas, Marin County, California. Rhizonema females are annulated over their entire bodies, are wholly embedded in host tissue, and secrete an abundant amount of gel material. Mature females do not form a cyst. The vulva is located on a large posterior terminal cone, and the anus is on the dorsal vulval lip. Esophageal glands of the second-stage larvae fill more than half of the body cavity. Tails of the vermiform males are blunt, and a cloacal tubus is …

Aspects Of The Biology Of The Red Drum, Sciaenops Ocellatus, In Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Several hundred specimens of the red drum from Mississippi were critically assessed. Regression equations for standard-length (SL) versus total-length differed between males and females and between small and large members of the same sex. Asingle regression line represented the weight-SL relationship for males with females. For condition coefficients to be helpful, fish had to be grouped at least by sex, season, and length or stage of maturity. By 12 months of age, most fish were about 30 to 32 cm SL and their distribution ranged throughout Mississippi Sound rather than being restricted to inshore bayou and marsh habitats like younger …

Aspects Of The Biology Of The Spotted Seatrout, Cynoscion Nebulosus, In Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

About 3,000 specimens of the spotted seatrout from Mississippi Sound and adjacent water grouped by males and females had a nearly identical standard Iength (SL) versus total length (TL) relationship, although the equation for males in winter differed from that for those in other seasons. When investigating the SL-weight relationship, some differences occurred both among seasons and between sexes. Therefore, condition coefficients (K) were calculated to compare male and female groups according to their length and state of maturation on a seasonal basis. The hepatosomatic index (HSI) tended to increase with fish length, with relatively high values occurring in winter …

Organization Of Sporulated Oocysts Of Eimeria Funduli In The Gulf Killifish, Fundulus Grandis, William E. Hawkins, John W. Fournie, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Oocysts of Eimeria funduli were studied by transmission electron microscopy in naturally-infected livers of the Gulf killifish, Fundulus grandis. Tissues were cryo-processed because membranous structures in the oocyst appear to hinder routine fixation and embedment. The oocyst wall (about 25 nm thick) was adjacent to the host cell and consisted of an outer membrane that limited the host cell cytoplasm and an inner membrane separated from the outer membrane by a narrow space. In some specimens, dense material was applied to the inner face of the inner membrane. Individual sporocysts were surrounded by a membranous "veil" (about 25 nm …

Natural Killer Activity In Gardner's Syndrome, Ann Marie Stembridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Gardner's syndrome is an autosomal dominant disease presenting multiple colonic polyps with a predisposition for malignant change. In addition to colonic polyp formation by early adolescence, extracolonic lesions appear often prior to polyp formation. One theoretical mechanism for the origin of polyps and malignancies in Gardner's syndrome is a genetic defect in the natural killer cell activity of patients with this disease. Natural killer cells are a subpopulation of lymphocytes that spontaneously lyse tumor cells and virally transformed cells. A study was undertaken to determine the natural killer activity of patients with Gardner's syndrome.

A technique termed chromium release was …

Evaluation Of The Status Of Texanocotyle Pogoniae And Laterocotyle Padreinsulae (Trematoda: Aspidogastridae), Sherman S. Hendrix, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Simpson and McGraw (1979, Southwest. Nat. 24: 557-562) erected two genera for two new species of aspidogastrid trematodes infecting the black drum, Pogonias cromis (Linnaeus), along the Texan Gulf of Mexico coast. Examination of holotypes and paratypes of each reveals that the two species have been described previously and that the genera are invalid.

Occurrence And Pathogenicity Of Heligmosomoides Spp. (Nematoda: Heligmosomidae) Associated With Cecal Villi In Arvicolid Rodents, Robert L. Rausch, M. L. Johnson

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The host response to the nematodes Heligmosomoides hudsoni (Cameron, 1937) and H. johnsoni Rausch and Rausch, 1973 (Heligmosomidae) was investigated in their natural hosts, varying lemmings, Dicrostonyx spp., and heather voles, Phenucomys intermedius Merriam (Rodentia: Arvicolidae), respectively. The nematodes occupy the cecum of the host, where they coil tightly around the long cecal villi. In individual animaIs, the comparatively few villi occupied became much enlarged, exhibiting severe hyperplasia of the mucosa and other microscopic changes, as described. The mechanism of pathogenesis involved three factors: strangulation of the villi, pressure atrophy, and chronic irritation by the crests of the synlophe. In …

Cuticular Ridge Patterns Of Nematodirus (Nematoda: Trichostrongyloidea) Parasitic In Domestic Ruminants Of North America, With A Key To Species, J. R. Lichtenfels, P. A. Pilitt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The six species of Nematodirus parasitic in domestic ruminants of North America have been identified previously on the basis of characteristics of the bursa and tips of the spicules, and females could not be identified. In an effort to find additional diagnostic characteristics of both sexes, cuticular ridges were studied with light and scanning electron microscopy and in whole mounts and cross sections. After the cuticular ridges of males were characterized, females were matched with males by means of cuticular ridges, except for the rare species N. davtiani. Five of the six species have variations of an 18-ridge bilaterally …

Generation, Isolation And Assay Methods For Human Lymphocyte Mitogenic Factor, Thomas E. Seay

Electronic Theses and Dissertations

Activated lymphocytes secrete many products including the lymphokine human lymphocyte mitogenic factor (HLMF). In preliminary experiments lymphocytes from peripheral blood and palatine tonsils were evaluated as possible sources of HLMF by evaluating their level of activation through screening their spontaneous and concanavalin A (con A)-induced blastogenic responses. Tonsil lymphocytes (TL) were found to have high spontaneous proliferation as compared to peripheral blood lymphocytes (PBL). Cells from both sources responded to con A by undergoing a typical blastogenic response. Because TL must be obtained septically, they are frequently cultured in the presence of the antimycotic agent, Amphotericin B (Am B). Since …

Tonsil Cell Products Which Modify In Vitro Proliferation Of Blood Lymphocytes, Thomas W. Hodge

Electronic Theses and Dissertations

Human palatine tonsil lymphocytes, when compared to peripheral blood lymphocytes (PBL), were in an activated state even though there was no in vitro stimulation. When these tonsil lymphocytes were cultured in the absence of serum and polyclonal mitogens or antigens, the supernatant fluid often inhibited the proliferative response of target PBL to con A. The extent of this suppression ranged from 22% to 84%, and target cell viability was 90% or greater. There was no evidence for the presence of immunoglobulins or (alpha)2-macroglobulin in whole supernatant fluids. The suppressor was partially denatured at 80(DEGREES)C and was rendered completely inactive upon …

Effects Of Various Treatments On The Distribution In Rats Of Immune Complexes Containing Antigens Of Mulv Leukemia Virus, Wail M. Siag, Jean Matchett, Joe M. Jones

Journal of the Arkansas Academy of Science

Immune complexes (IC) containing antigens of MuLV (¹²⁵lp30-anti-p30 or ¹²⁵lp70-anti-gp70) and formed in vitro or in vivo were sequestered primarily in the spleen. Treatments of rats with trypan blue, known to inhibit the reticuloendothelial system (RES) and diethylstilbestrol (DES), known to stimulate the RES, resulted in slight but not significant reduction of uptake of IC by the spleen. Splenectomy did not increase sequestration of IC by the liver nor did it change the distribution of IC in other tissues. Protein A, a cell wall protein of Staphylococcus aureus, when injected with IC resulted in a 10-fold reduction of uptake of …

The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink

Karl Reinhard Publications

Multi-individual cremation deposits found in the upper Santa Cruz River drainage were previously interpreted as the result of hypothesized cultural contact in the area. A review of 50 cremation deposits for which detailed analyses are available indicates that mulii-individual cremation deposits are the result of incomplete gleaning practices and have doubtful cultural significance. Hypotheses are generated from the present data which account for the apparent variation in cremation practices within the study area.

Pinworms And Primates: A Case Study In Coevolution, Daniel R. Brooks, David R. Glen

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cladistic analysis of 13 species of Enterobius based on 31 morphological characters supports the notion that pinworms and primates have co-speciated. A possible exception is the relationship between Enterobius vermicularis and Homo. Enterobius vermicularis is postulated to be the sister-species of E. buckleyi + E. lerouxi + E. anthropopitheci. Thus, if co-speciation has occurred, Homo is the sister-group of Pongo + Gorilla + Pan. Examination of the possibility that E. vermicularis in Homo is the result of host-switching or that Homo has been misclassified demonstrates that the latter possibility is the more parsimonious one.
