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 کاملCharacterization of Clostridium botulinum spores and its toxin in honey
Botulism is a serious paralytic disease caused by Clostridium botulinum toxin in foods. There are seven recognized serotypes of botulinum neurotoxins among which the principal prevalent types in humans include A, B and E. Infant botulism results from intestinal colonization and toxin production by C. botulinum spores in babies less than 1 year old. Honey is the most important food discriminated...
متن کاملIsolation and Characterization of Clostridium botulinum
A procedure is described for the preparation in homogeneous form of the neurotoxin found in cultures of Clostridium bofulinum type B. The toxin is a protein of molecular weight 167,000 and consists of at least two subunits. The molecular weights of the subunits are approximately 59,000 and 104,000. The toxin is irreversibly inactivated by p-chloromercuribenzoate, iodoacetic acid, and iodoacetam...

متن کاملAtypical toxin variant of Clostridium botulinum type B associated with infant botulism.
An atypical toxin variant of Clostridium botulinum (strain 657) was isolated from the feces of a 6-week-old female infant whose symptoms and clinical history were consistent with infant botulism. Toxin detected in the feces and the toxin produced by isolates from the feces and from two rectal swabs could be neutralized by type B botulinal antitoxin only at very high ratios of of antitoxin to to...
