Fatal family outbreak of Bacillus cereus-associated food poisoning.
Bacillus cereus is a well-known cause of food-borne illness, but infection with this organism is not commonly reported because of its usually mild symptoms. A fatal case due to liver failure after the consumption of pasta salad is described and demonstrates the possible severity of the emetic syndrome.
متن کاملMolecular epidemiology of Bacillus cereus food poisoning.
OBJECTIVES To investigate the potential use of DNA techniques in epidemiological diagnosis of Bacillus cereus food poisoning. SUBJECTS Fifty six B. cereus isolates from milk were studied. DESIGN The 56 B. cereus isolates were characterised into enterotoxin positive (27 isolates) and enterotoxin negative (29 isolates) using reverse passive latex agglutination technique. SETTING Plasmid and...
متن کاملBacillus cereus produces several nonproteinaceous insecticidal exotoxins.
Bacillus cereus is mainly known as a human food-borne opportunistic pathogen. Here, we used biological assays and HPLC to investigate the ability of B. cereus to produce insecticidal exotoxins during the stationary growth phase. None of the 575 B. cereus strains screened produced detectable levels of beta-exotoxin I, a small, heat-stable insecticidal nucleotide analogue. However, six out of a s...
متن کاملIdentification of Bacillus cereus group species associated with food poisoning outbreaks in British Columbia, Canada.
Food poisoning laboratories identify Bacillus cereus using routine methods that may not differentiate all Bacillus cereus group species. We recharacterized Bacillus food-poisoning strains from 39 outbreaks and identified B. cereus in 23 outbreaks, B. thuringiensis in 4, B. mycoides in 1, and mixed strains of Bacillus in 11 outbreaks.
متن کاملSevere clinical conditions associated with Bacillus cereus and the apparent involvement of exotoxins.
Twenty-one cases of infection with Bacillus cereus are summarised. The histories supplied showed that at least 15 of these were associated with severe or potentially severe symptoms including two deaths. Analysis of the production of exotoxins, including haemolysin and phospholipase, by these strains is given, and the relevance of these metabolites to the severity of the condition is discussed....
