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.
将51株与食物相关的蜡样芽孢杆菌菌株的产肠毒素谱与37株蜡样芽孢杆菌食物中毒菌株的产肠毒素谱进行了比较。与食源性菌株(37%和33%)相比,腹泻菌株中cytK以及hbl-nhe-cytK肠毒素基因的关联更为常见(73%和63%)。与腹泻菌株不同,食源性菌株显示出频繁的nhe和hbl基因多态性,并且通常是低毒素产生者。
