Storage stability of Clostridium botulinum toxin and spores in processed cheese.
Growth initiated from detoxified spores of Clostridium botulinum 62A resulted in toxin production of 50 to 10,000 mouse lethal doses (MLD) per gram of processed soft surface-ripened cheese. Regular assays during subsequent storage of toxic samples at 2 to 4 C revealed a characteristic two- to fivefold increase in toxin titer during the initial 1 week to 12 months of storage. Thereafter, the tox...
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 کاملNisin Resistance in Clostridium botulinum Spores and Vegetative Cells.
The frequencies at which vegetative cells and spores of Clostridium botulinum strains 56A, 62A, 17409A, 25763A, 213B, B-aphis, and 169B formed colonies on agar media containing 0, 10(sup2), 10(sup3), and 10(sup4) IU of nisin per ml at 30(deg)C were determined. Strain 56A had the highest frequencies of nisin resistance, while strains 62A, 169B, and B-aphis had the lowest. For most strains, spore...
