对天坛医院６００例产妇及其所娩新生儿Ｂ族链球菌（ＧＢＳ）带菌情况进行调查，结果表明，８％产妇和６．７％的新生儿围产期带有ＧＢＳ，总带菌率为１３％。ＧＢＳ阳性产妇早产和低体重儿的发生率较ＧＢＳ阴性者为多，其既往发生流产的平均次数也较多。但本组没有发现ＧＢＳ阳者携带者的胎膜早破和ＩＵＧＲ的发生率较阴性者高。分离的ＧＢＳ主要为Ⅲ型，其次为Ⅰａ型。抗生素敏感试验结果表明，对所有抗生素有耐药者均有一半以上菌株，其中对青霉素和庆大霉素耐药者高达９０％以上，推测与国内滥用抗生素有关，将给临床选药带来一定困难，应引起重视。
Investigation of 600 pregnant women and the neonates with B streptococci (GBS) carried by Tiantan Hospital showed that 8% of pregnant women and 6.7% of newborns had GBS during the perinatal period with a total carrier rate of 13 %. GBS positive maternal premature and low birth weight children than those with negative GBS were more, the average number of previous miscarriage also more. However, this group did not find GBS positive carriers of premature rupture of membranes and IUGR incidence was higher than negative. Isolated GBS is mainly type Ⅲ, followed by Ⅰ a type. Antibiotic susceptibility test results showed that more than half of all strains resistant to all antibiotics, of which penicillin and gentamicin resistant up to 90% or more, speculated that the abuse of antibiotics in the country, will bring certain clinical drug selection Difficulties, should pay attention.
