目的 了解假单胞菌医院感染现况 ,探讨防治对策。方法 对全院 6年间医院感染调查病例中临床标本分离出假单胞菌者 176例进行回顾性分析。结果 共分离出假单胞菌 194株 ,其中铜绿假单胞菌 96株 (4 9.48% ) ,非铜绿假单胞菌 98株 (5 0 .5 2 % ) ,非铜绿假单胞菌中嗜麦芽假单胞菌 46株 (2 3.71% ) ,占第 1位 ,病原菌分布在脓液 /分泌液中最多 48.45 % ,其次为痰 30 .93%、尿 12 .89%。结论 假单胞菌感染易发生于各种原因导致的免疫机能下降者 ,在临床标本中分布广泛 ,且对抗生素的耐药性逐渐增加 ,应重视假单胞菌在医院感染中的作用
Objective To understand the status of Pseudomonas nosocomial infection and to explore the control strategies. Methods A retrospective analysis was performed on 176 cases of Pseudomonas isolated from clinical specimens of hospital infection in the 6 years of the hospital. Results A total of 194 strains of Pseudomonas were isolated, of which 96 strains (4 9.48%) were Pseudomonas aeruginosa, 98 strains (55.02%) were non-Pseudomonas aeruginosa, 46 strains of Pseudomonas maltophilia (2 3.71%) accounted for the first place, the pathogen was distributed in pus / exudate up to 48.45%, followed by sputum 30.93% and urine 12.89%. Conclusions Pseudomonas infection is prone to decline in immune function due to various reasons. It is widely distributed in clinical samples and the resistance to antibiotics is gradually increasing. The role of Pseudomonas in nosocomial infections should be emphasized
