自西安地区医院分离的118株绿脓杆菌的“O”血清分型(群)

On Serum Typing of Pseudomonas aeruginosa(118 Strains)Isolated from Hospital in Xi'An District

血清分型是检测绿脓杆菌交叉感染和追踪其感染源的重要工具。本文用国内生产的绿脓杆菌诊断用12群“O”血清,对自西安市11所医院临床病人创面、呼吸道和尿路感染分离的118株绿脓杆菌进行了血清学分型鉴定。结果发现,118株绿脓杆菌中有115株能被“O”血清凝集,鉴定率为97.46%;有109株能被分型,分型率为92.37%。其中以血清Ⅵ.Ⅰ.Ⅲ三群菌多见,表明西安地区医院绿脓杆菌感染以这三个血清群为主。

Typing serum was an important tool for determination of the origin infectious foci of Pseudomonas aeruginosa.Pseudomonas ae- ruginosa(118 strains)isolated from 11 hos- pitals in Xi'An were determined by 12 O- polyvalent group serum of Pseudomonas ae- ruginosa.The results indicated that 115 stra- ins could be agglutinated by group O-poly- valent serum,determinant rate of the organi- sms found was 97.46%,109 strains could be typed by the 12 group O-serum,the typing rate was 92.37%.The investigation indicated that Pseudomonas aeruginosa infections in Xi'An were mainly due to serotypes Ⅰ,Ⅲ, Ⅵ.
