摘　　要：目的 :了解肺部感染病原菌群的变迁情况。方法 :对 1996～ 1999年肺部感染病原菌进行回顾性分析。结果 :共分离出 2 6 13株病原菌 ,其中革兰氏阴性杆菌、阳性球菌分别占 5 9 4%和 19 9%。各病原菌排列依次为铜绿假单胞菌、白色念珠菌、凝固酶阴性葡萄球菌、大肠埃希菌、嗜麦芽窄食单胞菌、克雷伯菌属、肠杆菌属和金黄色葡萄球菌等。所调查的 4年中 ,铜绿假单胞菌均占首位且构成比由 1996年的 2 4 2 %上升为 1999年的 36 4%。结论 :肺部感染病原菌发生了变迁 ,以革兰氏阴性杆菌为主 ,以往致病性较弱的革兰氏阳性菌有上升趋势 ,值得注意。Objective:To study the changes of the pathogen flora of pulmonary infection.Methods:By retrospective investigations from 1996 to 1999,the pathogen of pulmonary infection was analyzed.Results:Among the isolated 2 613 strain pathogens,gram_negative bacteria and gram_positive cocci were 59 4% and 19 9%,respectively.The pathogens in turn were Pseudomonas aeruginosa and Candida albicans and coagulase_negative Staphylococcus and Escherichia coli and Klebsiella and Enterobacter and Staphylococcus aureus and so on.The first isolated was Pseudomonas aeruginosa from 24 2% in 1996 up to 36 4% in 1999 in those years.Conclusion:The pathogen of pulmonary infection has been changed.The gram_negative bacteria play a predominant role and the opportunistic pathogen has the tendency of increa_sing.
