This isolate was associated with an emetic outbreak in 1972. Bacillus cereus AH187

Bacillus cereus AH187. This strain was isolated from the vomit of a person having eaten cooked rice by the Public Health Laboratory Service (PHLS), London, UK. The isolate was associated with an emetic outbreak in 1972. The strain is positive for cereulide (emetic toxin) formation, is negative for the HBL hemolytic enterotoxin and cytotoxin K, but carries the non-hemolytic NHE enterotoxin. The strain has been extensively characterized as part of a study recently published by Ehling-Schulz et al. (2005 Microbiology 151, 183-197), in which this isolate was characterized as sequence type 26 using the MLSTDB scheme that is commonly used to type the B. cereus group. Sequence was obtained from three libraries - a fosmid library (33-39 kb; 31,496 reads), a medium insert library (10-12 kb; 24,786 reads), and a small insert library (3-5 kb; 12,286 reads).

蜡样芽孢杆菌（Bacillus cereus）AH187。该菌株由英国伦敦公共卫生实验室服务部（Public Health Laboratory Service, PHLS）从食用过熟米饭的人员的呕吐物中分离得到，与1972年一起呕吐毒素型食源性暴发疫情相关。该菌株可合成呕吐毒素（cereulide），对HBL溶血性肠毒素与细胞毒素K（cytotoxin K）检测呈阴性，但携带非溶血性NHE肠毒素（non-hemolytic enterotoxin, NHE）。该菌株已被全面表征，作为Ehling-Schulz等人2005年发表于《Microbiology》第151卷第183-197页的研究内容之一，该研究采用蜡样芽孢杆菌群通用的多位点序列分型数据库（Multilocus Sequence Typing Database, MLSTDB）分型方案，将此分离株鉴定为序列型26（sequence type 26）。该菌株的测序序列来源于三个文库：黏粒文库（fosmid library，插入片段长度33-39 kb，共31496条读段（reads））、中等插入片段文库（medium insert library，插入片段长度10-12 kb，共24786条读段（reads））以及小插入片段文库（small insert library，插入片段长度3-5 kb，共12286条读段（reads））。
