Creator:: Craig, James Morrison
Abstract:: Interest in the distribution of Clostridium botulinum type E was heightened by the sudden outbreak of human botulism from smoked whitefish chubs and canned tuna fish in 1963. The question arose as to how widely the organism is distributed among fish and shellfish in the Northwest and what potential hazard...

Creator:: Paterno, Visitacion Asi
Abstract:: The difficulties encountered in working with micro-quantities of lipids have been overcome by the advent of new and improved procedures in chromatography which have made possible better fractionation and identification. Bacterial lipids because of their different lipid pattern from other life forms have stimulated much interest. Studies have been made...

Creator:: Niedermeyer, Glenn John
Abstract:: Polyacrylamide gel disc electrophoresis of concentrated culture media which had supported growth of Clostridium botulinum types A and B was shown to be effective in separating the toxin molecules from hemagglutinating molecules. Since the hemagglutinins of the two types are immunologically identical and are present in toxin and toxoid preparations,...

Creator:: Kimble, Charles E.
Abstract:: The primary purpose of this investigation was to characterize the lipids of the spores and vegetative cells of Cl. botulinum. A second purpose was to explore the possibility that lipids might serve as a means of differentiating the chiefly proteolytic Cl. botulinum type B from the nonproteolytic Cl. botulinum types...

Creator:: Stiebrs, Anita
Abstract:: The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification of Clostridium botulinum type E strains, and to develop a more reliable method and media for the differentiation of this organism based on the "pearly...

Creator:: Balstraz, Edwina Gene
Abstract:: In this study of toxigenic and non-toxigenic strains of Clostridium botulinum type E, attempts were made to induce toxin production in non-toxigenic cultures by exposure to mutagenic agents and to differentiate the organisms by immunodiffusion. First, cultures of non-toxic Cl. botulinum type E were exposed to various mutagenic agents in...

Creator:: McCollough, Marian Lorraine
Abstract:: Routine studies of bacterial fatty acid and lipid composition, made possible by recently developed techniques, have brought about an increasing interest in the physiological significance of these compounds. The purpose of this study was to characterize the fatty acids of the vegetative cells of Clostridium botulinum 33A, as the first...
