Outbreak of Clostridium perfringens food poisoning.
An outbreak of diarrhoea occurred at a 647-bedded long-stay hospital from 11 to 14 June 1989. Fifty-eight elderly residents developed symptoms and there were two deaths. The organism was identified as Clostridium perfringens type A, serotype TW23. The source of the outbreak was found to be inadequately reheated minced beef served at lunchtime on 11 June. The reason why only 4 of the possible 16...
متن کاملDistribution of neuraminidase among food-poisoning strains of Clostridium perfringens.
A survey was made to determine the distribution of the enzyme neuraminidase among 76 strains of Clostridium perfringens. Representative strains from each toxigenic type (A to F) and atypical C. perfringens type A food-poisoning strains of both American and English (Hobbs types) origin were tested. Both the American food-poisoning and nonfood-poisoning associated cultures consisted of both neura...
متن کاملUse of dogs as an assay for Clostridium perfringens enterotoxin.
Three techniques for using the dog as an assay organism for Clostridium perfringens enterotoxin are described. These are believed to be more convenient than ligated ileal-loop procedures.
متن کاملSynthetic DNA probes for detection of enterotoxigenic Clostridium perfringens strains isolated from outbreaks of food poisoning.
Four synthetic oligonucleotides encoding different parts of the Clostridium perfringens enterotoxin gene were used to test the enterotoxigenicity of C. perfringens strains isolated from confirmed outbreaks of food poisoning. Of the 245 strains isolated from food and feces originating from 186 separate outbreaks, 145 (59%) gave hybridization reactions with each of the four DNA probes used, while...
متن کاملIdentification and Characterization of a New Enterotoxin Produced by Clostridium perfringens Isolated from Food Poisoning Outbreaks
There is a strain of Clostridium perfringens, W5052, which does not produce a known enterotoxin. We herein report that the strain W5052 expressed a homologue of the iota-like toxin components sa and sb of C. spiroforme, named Clostridium perfringens iota-like enterotoxin, CPILE-a and CPILE-b, respectively, based on the results of a genome sequencing analysis and a systematic protein screening. ...
