A provisional serotyping scheme was used to type cultures of Bacillus cereus from 84 outbreaks of food poisoning in seven countries; 283 of the 337 (84%) cultures tested were typable. In 35 of the 61 outbreaks associated with a vomiting-type syndrome, foods, clinical specimens or both yielded H-serotype 1 only. Type 1 strains together with other sterotypes were isolated in seven outbreaks. In 14 outbreaks types 3, 4, 5, 8 or a mixture of serotypes were present. Untypable strains were isolated in five outbreaks. Two of the nine diarrhoeal-type outbreaks yielded serotype 1 only. Types 2, 6, 8, 9, 10 and a mixture of type 12 and an untypable strain appeared to be responsible for one outbreak each. Although 16 of the 18 recognized serotypes were present among cultures of B. cereus from various routine foods, only 156 of the 400 (39%) isolates tested were typable.
采用一种临时血清分型方案对来自七个国家84起食物中毒事件的蜡样芽孢杆菌培养物进行分型；337份受试培养物中有283份（84%）可分型。在与呕吐型综合征相关的61起事件中，有35起事件的食物、临床标本或两者中仅分离出H-1血清型。在7起事件中分离出1型菌株及其他血清型。在14起事件中存在3、4、5、8型或多种血清型的混合。在5起事件中分离出不可分型菌株。9起腹泻型事件中有2起仅分离出1型血清型。2、6、8、9、10型以及12型与一种不可分型菌株的混合似乎分别导致了1起事件。尽管在来自各种常规食物的蜡样芽孢杆菌培养物中存在18种公认血清型中的16种，但400份受试分离株中只有156份（39%）可分型。
