Enterotoxigenic profiles of food-poisoning and food-borne Bacillus cereus strains

J Clin Microbiol. 2002 Aug;40(8):3053-6. doi: 10.1128/JCM.40.8.3053-3056.2002.

Abstract

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 toxin producers.
