Characterization 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 کاملEffect of lysozyne on the recovery of heated Clostridium botulinum spores.
Lysozyme in the recovery medium increased the recovery of heated spores, thereby raising the measured heat resistance of type E Clostridium botulinum spores about 1,800-fold and type A spores up to 3-fold.

Sporulation of Clostridium botulinum types A, B, and E, Clostridium perfringens, and Putrefactive Anaerobe 3679 in dialysis sacs. J. Bacteriol. 85:126-133. 1963.-Concentrated cultures of spores of Clostridium botulinum type A (33A, 37A), B (41B, 51B)...
متن کاملInfluence of transition metals added during sporulation on heat resistance of Clostridium botulinum 113B spores.
Sporulation of Clostridium botulinum 113B in a complex medium supplemented with certain transition metals (Fe, Mn, Cu, or Zn) at 0.01 to 1.0 mM gave spores that were increased two to sevenfold in their contents of the added metals. The contents of calcium, magnesium, and other metals in the purified spores were relatively unchanged. Inclusion of sodium citrate (3 g/liter) in the medium enhanced...
متن کاملPathogenesis of Clostridium botulinum Type A: Study of In Vivo Toxin Release by Implantation of Diffusion Chambers Containing Spores, Vegetative Cells, and Free Toxin.
Millipore diffusion chambers (MDC) with 0.22-mum filters loaded with spores or vegetative cells of Clostridium botulinum were surgically implanted intraperitoneally (ip) into guinea pigs. MDC expose C. botulinum spores or vegetative cells to body fluids yet protect them from phagocytes. Guinea pigs receiving MDC containing 10(9) spores plus 10(8) polymorphonuclear (PMN) leukocytes and MDC with ...
