摘要
目的：探讨呼吸内科下呼吸道感染患者的病原菌种类分布及其耐药性，以协助临床合理应用抗菌药物。方法：以回顾性方法分析从2005—2009年医院呼吸内科下呼吸道感染患者痰标本分离出的病原菌及耐药情况。结果：革兰阴性杆菌占69．8％，对亚胺培南、哌拉西林／他唑巴坦及阿米卡星耐药率为2．96％-9．13％；革兰阳性球菌为20．06％，仅对万古霉素耐药率为0；真菌为10．14％。结论：呼吸内科下呼吸道感染，革兰阴性杆菌为主，革兰阳性球菌呈上升趋势，真菌占一定比例，耐药率不断提高；加强耐药性监测，合理应用抗菌药物十分重要。
Objective To discuss the distribution of pathogens isolated from the hospitalized patients of lower respiratory infection in the department of respiratory medicine and their drug resistance to help reasonably use of the antibiotics. Methods By the retrospective methods, we analyzed the pathogens isolated from the sputa of the hospitalized patients with lower respiratory tract infection in the department of respiratory medicine from 2005 to 2009 and their drug resistance. Results Gram--negative bacteria were 69.8%, the drug resistance ratio to imipenem, piperacillin/tazobactam and amikacin were 2.96%- 9.130%; Gram-positive bacteria were 20.06%, only to vancomycin were without resistance. Fungi were 10. 14%. Conclusion Gram-negative bacteria are the main ones in lower respiratory tract infection, Gram--positive bacteria have a rising tendency and fungi occupy a fixed ratio. The drug resistance increases constantly. So it is very important to utilize antibiotics reasonably and pay attention to drug resistance supervise.
