Germination of spores from Clostridium botulinum B-aphis and Ba410.
The germination of spores from Clostridium botulinum B-aphis and Ba410 was examined. In a complex medium, heat activation of spores from both strains doubled the germination rates and was required for germination in the presence of 2% NaCl. In a defined medium (CTB [D. B. Rowley and F. Feeherry, J. Bacteriol. 104:1151-1157, 1970]), the parent strain B-aphis germinated at a rate of 0.77% min-1 i...
متن کاملRequirements for germination of Clostridium sordellii spores in vitro.
Clostridium sordellii is a spore-forming, obligately anaerobic, Gram-positive bacterium that can cause toxic shock syndrome after gynecological procedures. Although the incidence of C. sordellii infection is low, it is fatal in most cases. Since spore germination is believed to be the first step in the establishment of Bacilli and Clostridia infections, we analyzed the requirements for C. sorde...
متن کاملGermination of Clostridium cylindrosporum Spores on Medium Containing Uric Acid.
Clostridium cylindrosporum spores germinated rapidly under reducing conditions when bicarbonate, uric acid, and calcium were present. Germination rates on 10 mM urate increased with increasing Ca (maximum rate at 5 mM Ca or greater). Germination rates on urate (limiting Ca) increased with increasing urate concentrations to 10 mM urate. At 10 mM Ca, germination rates reached a maximum at 1 mM ur...
متن کاملComparative pathogenomics of Clostridium tetani
Clostridium tetani and Clostridium botulinum produce two of the most potent neurotoxins known, tetanus neurotoxin and botulinum neurotoxin, respectively. Extensive biochemical and genetic investigation has been devoted to identifying and characterizing various C. botulinum strains. Less effort has been focused on studying C. tetani likely because recently sequenced strains of C. tetani show muc...
متن کاملDisinfection methods for spores of Bacillus atrophaeus, B. anthracis, Clostridium tetani, C. botulinum and C. difficile.
To evaluate disinfection methods for environments contaminated with bioterrorism-associated microorganism (Bacillus anthracis), we performed the following experiments. First, the sporicidal effects of sodium hypochlorite on spores of five bacterial species were evaluated. Bacillus atrophaeus was the most resistant to hypochlorite, followed in order by B. anthracis, Clostridium botulinum and Clo...
