Abstract

A collection of 829 isolates of Providencia stuartii, mostly from urological specimens of patients in 12 hospitals, were O serotyped. Hospitals varied in serotype distribution, but most isolates (97%) fell into one or another of 14 O types of P. stuartii. One type (O63) was found in 10 hospitals, and six types (O4, O17, O25, O52, O55, O56) were found in 5 or more hospitals. These seven types were more common than others and included 753 (91%) of the isolates. Only four isolates agglutinated in Providencia alcalifaciens antisera and, for increased efficiency in serotyping, it is recommended that separate schemes be employed for P. stuartii and P. alcalifaciens. Strains endemic in different hospitals may differ in serotype and give rise to nosocomial infections that are clinically recognizable when infections occur in obvious clusters. Nosocomial infections occurring in low frequency among patients not located close to each other in the hospital may be detected with the aid of serotyping.

摘要

收集了829株斯氏普罗威登斯菌分离株,大多来自12家医院患者的泌尿标本,并进行了O血清分型。各医院的血清型分布有所不同,但大多数分离株(97%)属于斯氏普罗威登斯菌的14种O型中的一种或另一种。一种类型(O63)在10家医院中被发现,六种类型(O4、O17、O25、O52、O55、O56)在5家或更多医院中被发现。这七种类型比其他类型更常见,包括753株(91%)分离株。只有四株分离株在产碱普罗威登斯菌抗血清中发生凝集,为提高血清分型效率,建议对斯氏普罗威登斯菌和产碱普罗威登斯菌采用不同的分型方案。不同医院的地方性菌株血清型可能不同,并引发医院感染,当感染以明显的聚集形式发生时,临床上是可识别的。借助血清分型可检测在医院中彼此不相邻的患者中发生的低频医院感染。
