Detection and identification of sporulating bacterium that involved in nosocomial infection

芽孢杆菌是一种产芽孢细菌，人们认为它是一种细胞在状态是孢子在医院引起医院感染。利用随机扩增多态性DNA（RAPD）-PCR方法对蜡状B.cereus类群的种和菌株进行了分类。属于蜡状B杆菌群的苏云金芽孢杆菌、蕈状芽孢杆菌、假蕈状芽孢杆菌和韦氏B杆菌，未报道其具有致病性。结果表明，苏云金芽孢杆菌、蕈状B杆菌、类蕈状芽孢杆菌和维亨斯台菲芽孢杆菌的基因组中含有致病相关基因。

The Bacilli is a sporulating bacterium, and it is thought that it is a cell in the state that is the spore in the hospital that causes nosocomial infection. It became possible to classify the species and strains of the B.cereus group according to random amplified polymorphic DNA (RAPD)-PCR method. B.thuringensis, B.mycoides, B.pseudomycoides, and B.weihenstephaensis that belonged to the B.cereus group to which it were not reported that there were a pathogenicity. It revealed that the genomes of B.thuringensis, B.mycoides, B.pseudomycoides, and B.weihenstephaensis possess some genes that involved in the p athogencity.
