The Effect Of Sodium Chloride On Beta-Hemolytic Streptococci, Bola Fashola

Masters Theses & Specialist Projects

The drug of choice for the treatment of Stieptococcal pharyngitis is penicillin G. However, a common home remedy prescribes the use of salt-water solutions for gargling.

Members of Beta -hemolytic streptococcal groups A, B, and C were isolated from the upper -respiratory tracts of patients diagnosed as having streptococcal pharyngitis. These cultures we:e obtained from HCA Greenview Hospital (Bowling Green, Kentucky) and used to study the effects of sodium chloride on the isolates.

The minimum inhibitory concentration of sodium chloride was determined for each of eight hospital isolates. Croup A streptococci were inhibited at a concentration of 7.2% sodium chloride …

Population Dynamics Of The Parasites In Fundulus Zebrinus In The Platte River Of Nebraska, John J. Janovy Jr., Eugene Lee Hardin

John Janovy Publications

The population dynamics of 7 parasite species or ecotypes were studied in the plains killifish, Fundulus zebrinus, at a single collection site in the South Platte River of Nebraska, U.S.A., for 5 yr. Parasites were: Myxosoma funduli (gill), Trichodina sp. (gill), Gyrodactylus bulbacanthus (gill), Urocleidus fundulus (gill), Gyrodactylus stableri (body surface), and Neascus sp. (= Posthodiplostomum; eyes and body cavity). Parasite densities, prevalences, and variance/mean ratios are reported for 22 samples, totaling 447 fish, over the summer months. Positive correlations were obtained between density and both standardized prevalence and log-transformed variance. Urocleidus fundulus populations were relatively stable with …

Hirschmanniella Pomponiensis N. Sp. (Nemata: Pratylenchidae), Parasitic On Bulrush, Scirpus Robustus Pursh, Fawzia Abdel-Rahman, Armand R. Maggenti

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

A new species of Hirschmanniella was found in bulrush roots; LM and SEM morphological studies revealed that it is distinct from other species in the genus. Therefore, it is designated Hirschmanniella pomponiensis n. sp. Six lips are fused to form a hexagonal labial plate, six inner sensilla encircle the stoma opening, and four cephalic sensilla open in the corners of subdorsal and subventral lips. Cephalic lip region consists of six or seven annuli. The female has incomplete areolation in the lateral field, the intestine overlaps the rectum, the tail tip is pointed and without annulation.

Meloidogyne Californiensis N. Sp. (Nemata: Meloidogyninae), Parasitic On Bulrush, Scirpus Robustus Pursh, Fawzia Abdel-Rahman, Armand R. Maggenti

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

Meloidogyne californiensis n. sp. is described and illustrated from bulrush Scirpus robustus in California. LM and SEM studies revealed that this species differs from other known species in the genus Meloidogyne especially by the prominent posterior cuticular protuberances in the female, the distinct shape of the perineal pattern which is marked by one prominent stria in the perineum, indistinct lateral lines, many broken discontinuous striae on both sides of the arch, and the excretory pore being located posterior to stylet base. Second-stage juveniles 448-628 μm long, stylet length 11-13 μm, styler delicate, with small knobs sloping posteriorly, cephalic region with …

Morphometric Analysis Of Anguina Amsinckiae From Three Host Species, Dan James Pantone, John A. Griesbach, Armand R. Maggenti

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

Amsinckia species (fiddleneck) in the South Coast Ranges of California were surveyed to determine if any of the 12 different California species of Amsinckia are hosts of the nematode, Anguina amsinckiae (Steiner and Scott, 1935) Thorne, 1961. Previously only Amsinckia intermedia Fischer and Meyer was reported as a host of Anguina amsinckiae. The survey established that there are at least two additional hosts of Anguina amsinckiae: Amsinckia lycopsoides Lehmann and Amsinckia gloriosa Suksdorf. Seven sites containing nematode-infected Amsinckia plants were discovered. Every site contained two or more species of Amsinckia; however, only one site contained more than …

Embryonic And Postembryonic Development Of Meloidogyne Californiensis Abdei-Rahman & Maggenti, 1987 [Research Note], Fawzia Abdel-Rahman, Armand R. Maggenti

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

The embryonic and postembryonic development of root-knot nematodes (Meloidogyne spp.) are well known and have been studied in detail. These studies have indicated that the ontogeny of rootknot nematodes is characterized by five developmental stages separated by four molts. In 1987, Abdel-Rahman and Maggenti described a new root-knot nematode species, Meloidogyne californiensis on bulrush (Scirpus robustus Pursh) in California. The objective of this note is to provide information on the ontogeny of M. californiensis.

A Reappraisal Of Tylenchina (Nemata). 4. The Family Anguinidae Nicoll, 1935 (1926), Renaud Fortuner, Armand R. Maggenti

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

The family Anguinidae is redefined. The families and subfamilies Nothotylenchidae/nae, Sychnotylenchidae/inae, Halenchidae/inae, Pseudhalenchinae, Ditylenchidae/nae, Cynipanguininae, Neoditylenchinae, Nothanguininae and Thadinae are rejected. The genera Anguina, Halenchus, Ditylenchus, Pseudhalenchus, Sychnotylenchus, Thada, Subanguina, Cynipanguina, and Pterotylenchus are recognized as valid in Anguinidae. Chitinotylenchus is a genus inquirendum or incertae sedis in Anguinidae. The following new synonyms are proposed: Nothotylenchus, Boleodoroides and Orrina synonyms of Ditylenchus; Nothanguina synonym of Anguina; Afrina and Mesoanguina synonyms of Subanguina; and Neoditylenchus synonym of Sychnotylenchus. Hypotheses on the evolution within Anguinidae are presented. A tabular key is includetod help identify the valid genera. …

A Reappraisal Of Tylenchina (Nemata) 1. For A New Approach To The Taxonomy Of Tylenchina, Michel Luc, Armand R. Maggenti, Renaud Fortuner, Dewey J. Raski, Etienne Geraert

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

During the last three decades plant-parasitic nematodes have received increasing attention. This was due mainly to the discovery during the years between 1943-1953 of the first efficient nematicides, DD, EDE and DBCP. This discovery gave a strong impetus to established nematology laboratories and led to the establishment of laboratories in previously "virgin," or nearly so, territories. As a result, there was an increase in the number of nematologists and taxonomic activity. This is particularly true in those areas new to nematology, because the soil fauna is virtually unknown and taxonomy is one of the few activities fitting with limited material …

Corrigendum: Revision Of The Name Eimeria Palustris Hertel And Duszynski, 1987, From Shrews (Sorex Spp.), Lynn Ann Hertel, Donald W. Duszynski

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

In the paper on shrew coccidians that appeared in the February 1987 issue of the Journal (Hertel and Duszynski, 1987, Journal of Parasitology 73: 172-183) we named one of our new species Eimeria palustris. Dr. N. D. Levine (University of Illinois) kindly informed us that the name E. palustris is preoccupied by an eimerian described from the rice rat, Oryzomys >palustris (Barnard, Ernst, and Stevens, 1971 , Journal of Parasitology 57: 1,293-1,296). We would like to rename the form we saw Eimeria longirostris for the specific name of the host in which the species was most prevalent.

Biochemical And Immunological Systematics Of Some Ascaridoid Nematodes: Genetic Divergence Between Congeners, Steven A. Nadler

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

Vertical starch gel electrophoresis and trefoil immunodiffusion were used to study the systematics of some ascaridoid nematodes. Within the Ascarididae, the time scale of divergence was too great for intergeneric electrophoretic comparisons. Congeneric electrophoretic comparisons of Baylisascaris procyonis (host- raccoon) versus Baylisascaris transfuga (host- Black bear), and Toxocara canis (host- domestic dog) versus Toxocara cati (host- domestic cat) yielded Nei genetic distance coefficients of 1.21 and 1.55, respectively. Estimates of times of divergence made from 1 electrophoretic clock calibration suggest that the Baylisascaris species have not shared a common ancestor for 25 million years (Myr), and that the Toxocara species …

Late Fall Transmission Of Nematodirus Battus (Nematoda: Trichostrongyloidea) In Western Oregon, Lora G. Rickard, Eric P. Hoberg, Gary L. Zimmerman, Jannell K. Erno

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

Studies on Nematodirus battusCrofton and Thomas, 1951, have shown a marked seasonality in the pattern of transmission. The life cycle normally involves only one parasitic generation per year. The infective third-stage larvae develop over the summer within eggs deposited on pasture. Eggs are sensitized by low temperatures during fall and winter; larval hatching follows in the presence of adequate moisture and proper osmotic conditions as the temperature rises above 10°C. This set of conditions, conducive to hatching, is regularly present only during spring; thus, hatching of eggs is concentrated into a few weeks during this time. Outbreaks of clinical …
