Improved detection methods and physiological studies of staphylococcal enterotoxin

Creator:: Kimble, Charles E.
Abstract:: The purpose of this study was to develop means to facilitate the detection of staphylococcal enterotoxin and to elucidate factors that influence enterotoxin formation. It was found that semipurification flat-gel electrophoresis in a water-cooled apparatus was more efficient than CM-cellulose and Sephadex column chromatography currently used to separate toxin from...

Methods of identifying food poisoning staphylococci

Creator:: Orth, Donald Simms
Abstract:: Several biochemical tests were studied to determine their correlation with coagulase activity. The lysozyme test was in perfect agreement with the coagulase test for the strains studied. Mannitol fermentation and egg yolk lipase tests were in agreement with the coagulase test for 96% of the coagulase positive strains. Sheep red...

Studies on the inhibition of food-borne pathogens and spoilage bacteria by lactic acid starter cultures

Creator:: Daly, Charles
Abstract:: The ability of Streptococcus diacetilactis to inhibit a variety of food-borne pathogens and spoilage organisms in milk and broth cultures was demonstrated. Test organisms inhibited included Pseudomonas and Alcaligenes species, Eschericia coli, Salmonella, Staphylococcus aureus, Clostridium perfringens and Vibrio parahaemolyticus. In general, approximately 99.0% and 99.9% inhibition was observed in...

Significance of pigments in radiation resistance of Micrococcus radiodurans

Creator:: Krabbenhoft, Kenneth Louis
Abstract:: An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

Creator:: Ley, Ronald Douglas
Abstract:: Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

DNA vaccines encoding the glycoprotein genes of spring viremia of carp virus, snakehead rhabdovirus, or infectious hematopoietic necrosis virus induce protective immunity in rainbow trout (Oncorhynchus mykiss) against an infectious hematopoietic necrosis virus lethal challenge

Creator:: Drennan, John D.
Abstract:: Recent advances in DNA vaccine technology has brought about a promising strategy for the control of viruses that contain surface membrane glycoproteins. This type of vaccine involves the intramuscular injection of a bacterial plasmid containing a gene encoding a viral protein. The strategy uses eukaryotic processing of the protein as...

Control of furunculosis in Pacific salmon by immunization

Creator:: Overholser, Donald Lee
Abstract:: The purpose of this project was to study the possibility of controlling furunculosis in salmonid fish using immunological procedures. Antiserum with an agglutinating antibody titer of 1:20,480 against Aeromonas salmonicida was produced in a horse. This hyperimmune serum was used to passively immunize coho salmon, Oncorhynchus kitsutch, (jacks). However, this...

Oral and parenteral immunization for the control of Vibrio anguillarum, the etiological agent of vibriosis in salmonid fish

Creator:: Rohovec, J. S.
Abstract:: Efficacious vaccines were developed for the control of Vibrio anguillarum, the etiological agent of vibriosis in salmonid fish. These bacterins can be administered either orally or parenterally. It was determined that both formalin-killed lyophilized whole cells and wet-packed whole cells of the organism are effective oral immunogens. Intraperitoneal injection of...

The incidence of Salmonella in gulls on the Oregon coast

Creator:: Berg, Ronald Wayne
Abstract:: Environmental swabs and meat samples from two of three seafood processing plants sampled on the Oregon Coast were found to contain Salmonella. Although these enteropathogens were not isolated from the finished products, the danger of contamination is great since the processing received by many seafoods is not designed to yield...
