Of approximately 300 cultures of Salmonella, representing 75 different serotypes, none was found to be as heat-resistant as S. senftenberg 775W. However, S. blockley 2004 was 5 times more heat-resistant and S. senftenberg 775W was 30 times more heat-resistant than S. typhimurium Tm-1, the reference strain in this study. All other strains of Salmonella(More)
OBJECTIVES This study aimed to identify modifiable mechanisms associated with low back injury in adolescent cricket fast bowlers. DESIGN A prospective study design examined the association between intrinsic risk factors, workload, bowling kinematics, lumbar load and low back injury incidence. METHODS Twenty-five injury free fast bowlers, aged 14-19(More)
Survivor curves for heat-resistant ascospores of Byssochlamys fulva exposed to lethal heat were nonlogarithmic. At lower heating temperatures, the log survivor curves were characterized by a shoulder plus an accelerating death rate; with increased temperatures, the rate approached logarithmic death. The formula (log No -- log N)a = kt + C was adapted to(More)
Supplementation of egg white at pH 8.9 with 5 mg of disodium ethylenediaminetetraacetic acid (EDTA) per ml resulted in a kill of Salmonella typhimurium Tm-1 of greater than 10(6) per ml after 28 days at 2 C. While at 28 C, supplementation with 7 mg of EDTA per ml resulted in approximately a 10(6) kill in less than 24 hr. Kena supplementation at 40 mg/ml of(More)
Hemolysis of human erythrocytes as a function of time of exposure to 47.4-54.5 degrees C was measured and correlated to thermal transitions in the membranes of intact erythrocytes as determined by differential scanning calorimetry (DSC). Curves of hemoglobin leakage (a measure of hemolysis) as a function of time have a shoulder region exhibiting no leakage,(More)
Bean (Phaseolus vulgaris L. cv. Dwarf) roots were inoculated with Rhizobium phaseoli and colonized by the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus fasciculatum Gerd. and Trappe or left uncolonized as controls. The symbiotic associations were grown in an inert substrate using 0, 25, 50, 100, or 200 milligrams hydroxyapatite (HAP)(More)
Ascospores from 25 strains of Byssochlamys were studied for their ability to resist heat treatment in a standard defined medium. Seven of these were able to survive heating at 90 degrees C for 25 min or longer, when initial numbers were frequently near 10(6)/ml. Ascospores from five resistant strains suspended in the medium at pH 5.0 were usually more(More)
Most strains of Salmonellae have simple nutritional requirements and grow well, therefore, in simple media consisting of glucose, inorganic nitrogen, and mineral salts (Kauffmann, 1954). There are, however, a number of Salmonellae which are unable to synthesize certain essential vitamins and amino acids and these must be supplied in the culture medium. The(More)
Conventional and nitrite-free frankfurters in loosely wrapped packages were compared as to their ability to support growth of Salmonella, Staphylococcus, and their naturally occurring spoilage flora at 7 C (simulating refrigerated storage) and 20 C (simulating possible temperature abuse). At 7 C Salmonella did not grow in either type of frankfurter;(More)
