Some factors influencing carbon dioxide production by Leuconostoc citrovorum

Creator:: Holmes, Beverly Ann
Abstract:: This study was undertaken to determine the role Leuconostoc citrovorum may play in carbon dioxide production in milk. The ability of L. citrovorum strains to produce gas was studied by two methods. A qualitative method used visual measurement of gas where an agar plug was forced up the neck of...

Ecology and applications of cutaneous mechanisms of resistance to amphibian chytridiomycosis

Creator:: Nebergall, Emily E.
Abstract:: Amphibian biodiversity is in rapid global decline, due in part to the fungal disease chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd). Susceptibility to Bd and chytridiomycosis varies between species and populations. Skin peptides and symbiotic skin bacteria appear to be important mechanisms of Bd resistance. However, not much is known about...

Certain chemical and immunological properties of the endotoxin from Vibrio anguillarum

Creator:: Abe, Patrick Masami
Abstract:: The Boivin agent from Vibrio anguillarum was extracted with the use of 0.25M trichloroacetic acid (TCA). Chemical analysis revealed that the endotoxin contained approximately 35.1% protein, 18.1% carbohydrate, 39.3% lipid, 1.8% glucosamine and evidence of ethanolamine. Sixteen different amino acids made up the protein. The aliphatic amino acid concentration was...

Analysis of salmonid leukocytes purified by hypotonic lysis of erythrocytes

Creator:: Crippen, Tawni L., Bootland, Linda M., Leong, Jo-Ann C., Fitzpatrick, Martin S., Schreck, Carl B., and Vella, Anthony T.
Abstract:: A technique that uses hypotonic lysis of erythrocytes was optimized for the purification of leukocytes from the peripheral blood and anterior kidney (pronephros) of rainbow trout Oncorhynchus mykiss. Comparisons of initial blood dilution (1:2, 1:4, and 1:6) and the time of exposure to hypotonic conditions (10, 20, and 40 s)...

The role of chlamydial inclusion membrane proteins in host-pathogen interaction and the development of novel methods for studying chlamydial biology

Creator:: Alzhanov, Damir T.
Abstract:: The majority of our modern understanding of bacterial pathogenesis is based on the strategy that involves screening bacterial genomes for the presence of the genes encoding pathogenic factors, and analysis of these genes via forward and reverse genetics. Chlamydiae represent a unique group of pathogenic bacteria in which it is...

Isolation and characterization of a leukocytolytic factor from Aeromonas salmonicida

Creator:: Fuller, David Wallace
Abstract:: The purpose of this study was to find what effect temperature and immunization has on the phagocytic activity of fish leukocytes against certain disease causing bacteria. Also proposed was the isolation and characterization of a leukocytolytic factor produced by one of these bacteria, Aeromonas salmonicida. Investigations revealed that temperature had...

Human health significance of vibrios from the aquatic environment

Creator:: Nishibuchi, Mitsuaki
Abstract:: For the enrichment and enumeration of Vibrio fluvialis, a broth medium was designed by modifying alkaline peptone (AP) medium. This new V. fluvialis enrichment medium (FEM) was shown to be more effective than AP medium in field samplings where a total of 177 samples (estuarine waters and sediment, sewage, and...

Assessing disease impacts of hatcheries on downstream salmonids in the Willamette River Basin, Oregon

Creator:: Jakaitis, Michelle
Abstract:: Hatcheries are often perceived as a source of pathogen amplification, potentially increasing disease risk to free-ranging populations; at the same time, free-ranging fishes may introduce pathogens into hatcheries through untreated water sources. Many pathogens exist naturally within the environment (with the exception of introduced pathogens) and the presence of a...

Monoclonal antibodies to 5'-deoxy-5' methylthioadenosine phosphorylase

Creator:: Parker, Ricardo Jerome
Abstract:: 5'-Deoxy-5'-methylthioadenosine phosphorylase catalyzes the phosphorolytic cleavage of 5'-deoxy-5'-methylthioadenosine to form 5'-deoxy-5'-methylthioribose-1-phosphate and adenine in mammalian cells and plays an important role in methionine and purine salvage. The enzyme is abundant in normal tissues and in cell lines derived from normal cells. However, several malignant tissues and cell lines have been...
