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 کاملContinuous production of Clostridium tetani toxin.
The continuous production of Clostridium tetani toxin has been carried out in a 1-liter stirred culture vessel for as long as 65 days. Toxin production of approximately 120 flocculating units per ml was maintained with a dilution rate of 0.125 hr(-1), a temperature of 34 C, a pH of 7.4, and the addition to the medium of 0.1 g of potassium chloride per liter. The average minimal lethal intraperi...

متن کاملCommon mesophilic anaerobes, including Clostridium botulinum and Clostridium tetani, in 21 soil specimens.
A relatively rich medium was markedly superior to a dilute medium for the isolation of anaerobic bacteria from soil. The obligate anaerobes isolated from 21 soil samples were all clostridia and the counts ranged from 2.7 X 10-2 to 3.3 X 10-6 per g. The organisms most frequently isolated were Clostridium subterminate, C. sordelii, C. sporogenes, C. indolis, C. bifermentans, C. mangenoti, and C. ...
متن کاملCellular Entry of Clostridium perfringens Iota-Toxin and Clostridium botulinum C2 Toxin
Clostridium perfringens iota-toxin and Clostridium botulinum C2 toxin are composed of two non-linked proteins, one being the enzymatic component and the other being the binding/translocation component. These latter components recognize specific receptors and oligomerize in plasma membrane lipid-rafts, mediating the uptake of the enzymatic component into the cytosol. Enzymatic components induce ...
