对在６个月内从１２１名产科新生儿中的３０名检出的３１株铜绿假单胞菌进行ＲＡＰＤ指纹图谱分析和血清学分型。２４株为Ｏ：６血清型，６株属于另外３个血清型，１株未能分型。ＲＡＰＤ分型率为１００％。３１个菌株分成５个ＲＡＰＤ谱型。２５株为Ｒ：１型，其它６株为另外的４个谱型。血清型不同的新生儿菌株的ＲＡＰＤ谱型亦不相同。２株Ｏ：１型的菌株，其ＲＡＰＤ谱型却不同。同期分别来自４个其他科室的５名患者的５株Ｏ：６型ＰＡ菌的ＲＡＰＤ谱型各自不同，与新生儿Ｏ：６型的ＲＡＰＤ谱型也不同。结果表明，铜绿假单胞菌在产科新生儿的暴发流行，Ｏ：６／Ｒ：１型为暴发流行菌株；ＲＡＰＤ分型率高，分辨力强，快速简便，颇具医院感染分子流行病学研究的应用价值。
RAPD fingerprinting and serological typing of 31 strains of Pseudomonas aeruginosa detected from 30 out of 121 obstetric neonates within 6 months were performed. 24 strains were O: 6 serotypes, 6 strains belonged to the other 3 serotypes, and 1 strain failed to type. RAPD typing rate was 100%. 31 strains were divided into 5 RAPD patterns. 25 strains were R: 1 type, the other 6 strains were the other 4 types. The RAPD patterns of different serotype neonates are also different. Two O: 1 strains showed different RAPD patterns. Five strains of O: 6 PA from five patients in four other departments in the same period had different RAPD patterns, which was different from that of neonatal O: 6 RAPD patterns. The results showed that Pseudomonas aeruginosa outbreak in neonatal obstetrics, O: 6 / R: 1 outbreak strains; RAPD high typing rate, resolution, quick and easy, quite a molecular epidemiology of nosocomial infection The application value.
