Molecular 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 کاملFatal 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 کاملEnterotoxigenic profiles of food-poisoning and food-borne Bacillus cereus strains.
The enterotoxigenic profiles of 51 B. cereus food-related strains were compared to those of 37 B. cereus food-poisoning strains. cytK and association of hbl-nhe-cytK enterotoxin genes were more frequent among diarrheal strains (73 and 63%) than among food-borne strains (37 and 33%). Unlike diarrheal strains, food-borne strains showed frequent nhe and hbl gene polymorphisms and were often low to...
متن کاملAn outbreak of Bacillus cereus food poisoning in a school hostel, Klang.
A food poisoning outbreak affected 114 female Malay students staying in a religious secondary school hostel in Klang. The students developed an illness mainly characterized by abdominal pain, nausea, vomiting and giddiness. The median incubation period in this outbreak was 2.5 hours. Laboratory examination of suspected food revealed 2.3 X106 Bacillus cereus organisms per gram of fried noodles. ...
متن کاملComparison of cytotoxin cytK promoters from Bacillus cereus strain ATCC 14579 and from a B. cereus food-poisoning strain.
The cytotoxin CytK produced by Bacillus cereus is believed to be involved in food-borne diseases. The transcriptional activity of the cytK promoter region in a food-poisoning strain was studied using a reporter gene and compared with that in the reference B. cereus strain ATCC 14579. In the food-poisoning strain, cytK is more strongly transcribed, possibly explaining the pathogenicity. The glob...
