Abstract

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.
