Ｂ群链球菌（ｇｒｏｕｐＢＳｔｒｅｐｔｏｃｏｃｃｕｓ，ＧＢＳ）在世界范围内是围产期产妇和新生儿严重感染性疾病的主要致病菌，为了解ＧＢＳ菌株的基因特点，我们在限制性酶切基础上，采用与多种特异ＧＢＳ基因探针和１６ＳｒＲＮＡ广谱探针杂交技术，对３４株北京株和１４
In the world, group B streptococcus (GBS) is the main pathogen of severe infectious diseases of perinatal maternal and newborn. To understand the genetic characteristics of GBS strains, based on restriction enzyme digestion, A variety of specific GBS gene probes and 16SrRNA broad-spectrum probe hybridization technology, 34 strains of Beijing and 14
