Detection and identification of sporulating bacterium that involved in nosocomial infection

芽胞杆菌是一种产孢子的细菌，一般认为它是一种处于医院孢子状态的细胞，引起医院感染。利用随机扩增多态性DNA (RAPD)-PCR方法对蜡样芽孢杆菌类群的种、株进行分类成为可能。属蜡样芽孢杆菌群的b.s thuringensis、b.s mycoides、b.s pseudoomycoides和b.s weihenstephaensis未见致病性报道。结果表明，苏云金芽孢杆菌、真菌芽孢杆菌、假菌芽孢杆菌和魏氏芽孢杆菌的基因组中含有与致病性相关的基因。

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.
