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...

Ecophylogenetic Characterization of the Gut Microbiome of At-risk Companion and Food Animals

Creator:: Kirchoff, Nicole S.
Abstract:: Agricultural and companion animals are integral to our way of life as they provide us with nourishment, financial resources, transportation, and companionship. However, pets, managed animals in the agricultural industry, as well as wild populations of food animals are all subject to health and mortality risks. The gut microbiome is...

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...

The role of Salmonella typhimurium type three secretion system (T3SS) and effector proteins in chromatophore cell response.

Creator:: Farhad, Mohammad
Abstract:: Bacterial contamination of food poses a great risk to human health worldwide. A chromatophore cell-based biosensor, utilizing B. splendens erythrophore cells, is an emerging technology that has shown potential to detect bacterial toxicity based on function-dependent mechanisms. Previous studies have investigated the response of erythrophore cells to foodborne pathogens, pesticides,...

Immune response and protection against Streptococcus pyogenes after vaccination with Lactococcus lactis that expresses conserved region of M6 protein

Creator:: Mannam, Praveen
Abstract:: Most pathogens gain access to their host through mucosal surfaces. It is therefore desirable to develop mucosal vaccines that elicit an immune response to prevent this crucial first step in infection. Current mucosal vaccines are live attenuated strains of pathogens. More recent efforts have focused on the use of recombinant...

The Effects of Phytoplankton Prey Species and Nutrient Limitation on Microzooplankton

Creator:: McBeain, Kelsey Ann
Abstract:: Phytoplankton and microzooplankton comprise the base and the first link of the marine food web, respectively. These microbes are key drivers of marine carbon and nutrient cycles. Phytoplankton convert atmospheric CO₂ into organic carbon, and microzooplankton consume phytoplankton, packaging phytoplankton carbon into particulate forms that have a variety of fates:...

Role of Plc in the germination of Clostridium perfringens food poisoning isolate SM101

Creator:: Bond, Colton B.
Abstract:: Clostridium perfringens is the causative agent of gas gangrene and the 3rd most common cause of type A food borne disease in the United States. Critical to the pathogenicity of C. perfringens is the ability of this bacterium to produce highly resistant, metabolically dormant spores that can resume metabolic function...

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...
