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 کاملThermal inactivation of nonproteolytic Clostridium botulinum type E spores in model fish media and in vacuum-packaged hot-smoked fish products.
Thermal inactivation of nonproteolytic Clostridium botulinum type E spores was investigated in rainbow trout and whitefish media at 75 to 93 degrees C. Lysozyme was applied in the recovery of spores, yielding biphasic thermal destruction curves. Approximately 0.1% of the spores were permeable to lysozyme, showing an increased measured heat resistance. Decimal reduction times for the heat-resist...
متن کاملIsolation of Clostridium botulinum type E from Cayuga Lake fish.
The vast majority of the isolations of Clostridium botulinum type E have been from marine fish and their environment, with very few from fresh-water lakes and streams. Johannsen (J. Appl. Bacteriol. 26:43, 1963) has found the organisms to be common in Norway and Sweden's coastal and river waters where the salinity is fairly low, and Prev6t and Huet (Bull. Acad. Natl. Med., Paris 135:432, 1951) ...
متن کاملComparative dose-survival curves of representative Clostridium botulinum type F spores with type A and B spores.
Radiation survival data of proteolytic (Walls 8G-F) and non-proteolytic (Eklund 83F) type F spores of Clostridium botulinum were compared with dose-response data of radiation-resistant type A (33A) and B (40B) spores. Strain Eklund 83F was as resistant as strain 33A, whereas strain Walls 8G-F was the most sensitive of the four strains tested. The methods suggested for computing both an initial ...
