Abstract
Pseudomonas aeruginosa was isolated in 22.2% of 305 intensive care unit environmental cultures. A high genetic heterogeneity (18 pulsotypes) was evident. Taps and related surfaces were a stable reservoir for certain pulsotypes. The 15.4% of the P. aeruginosa-positive cultures were polyclonal. Different colony morphotypes should be assayed in surveillance studies.
摘要
在305份重症监护病房环境培养物中，22.2%分离出了铜绿假单胞菌。明显存在高度的基因异质性（18种脉冲型）。水龙头及相关表面是某些脉冲型的稳定储存库。15.4%的铜绿假单胞菌阳性培养物为多克隆。在监测研究中应检测不同的菌落形态型。
