Clostridium botulinum type F: isolation from venison jerky.
A Clostridium botulinum type F was isolated from the venison jerky responsible for the only type F botulism outbreak reported in the United States. The isolate differed from the prototype Langeland type F strain in being nonproteolytic.
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 کاملIsolation of Clostridium botulinum from Honey.
Methods for the isolation of Clostridium botulinum from honey samples are described. A total of 9 of 90 honey samples were positive for C. botulinum; 6 of the positive samples had been fed to babies who developed infant botulism.
متن کاملPurification and properties of Clostridium botulinum type F toxin.
Clostridium botulinum type F toxin of proteolytic Langeland strain was purified. Toxin in whole cultures was precipitated with (NH4)2SO4. Extract of the precipitate was successively chromatographed on diethylaminoethyl-cellulose at pH 6,0, O-(carboxymethyl) cellulose at pH 4.9, and finally diethylaminoethyl-cellulose at pH 8.1. The procedure recovered 14 percent of the toxin assayed in the star...
متن کاملMolecular construction of Clostridium botulinum type F progenitor toxin.
Molecular dissociation of purified type F progenitor toxin with an S20,W of 10.3 and a molecular weight of 235,000 into two components, toxic and atoxic, was demonstrated by ultracentrifugation, gel filtration, and diethylaminoethyl-Sephadex chromatography at pH 7.5. The ultracentrifugal analysis indicated that type F progenitor toxin dissociates into components of the same molecular size of 5....
