Strains of Bacillus cereus and B. thuringiensis were tested by the Tecra VIA kit for the ability to produce a diarrhoeal enterotoxin. The strains of B. thuringiensis were isolated from commercial B. thuringiensis-based insecticides (Bactimos, DiPel, Florbac, FC, Foray 48B, Novodor FC, Turex, VecTobac, XenTari). The production of diarrhoeal enterotoxin varied by a factor of more than 100 among the different strains tested. B. cereus (F4433/73) produced the highest amount of enterotoxin and the B. thuringiensis strain isolated from DiPel the lowest. The products were tested for their content of diarrhoeal enterotoxin and all products, except MVP which does not contain viable B. thuringiensis spores, contained diarrhoeal enterotoxins. The results indicates an potential risk for gastroenteritis outbreak caused by B. thuringiensis.
使用Tecra VIA试剂盒检测了蜡样芽孢杆菌和苏云金芽孢杆菌菌株产生腹泻性肠毒素的能力。苏云金芽孢杆菌菌株是从基于苏云金芽孢杆菌的商业杀虫剂(Bactimos、DiPel、Florbac、FC、Foray 48B、Novodor FC、Turex、VecTobac、XenTari)中分离出来的。在所测试的不同菌株中,腹泻性肠毒素的产生量相差超过100倍。蜡样芽孢杆菌(F4433/73)产生的肠毒素量最高,而从DiPel中分离出的苏云金芽孢杆菌菌株产生的肠毒素量最低。对这些产品的腹泻性肠毒素含量进行了检测,除了不含活的苏云金芽孢杆菌孢子的MVP外,所有产品都含有腹泻性肠毒素。结果表明苏云金芽孢杆菌可能引发胃肠炎爆发。
