目的:了解呼吸道感染病原菌的分布及药敏情况,为临床合理用药提供依据。方法:对2005年7月至2005年12月住院病人送检痰标本中分离出的457例病原菌的构成比及药敏结果进行分析。结果:分离出的457例病原菌中G-杆菌310株(67.8%),G+阳性球菌127株(27.8%),白色念珠菌20株(4.4%),臭鼻克雷伯菌、铜绿假单胞菌、大肠埃希菌和金黄色葡萄球菌为主要病原菌。结论:肺结核病人在治疗过程中要根据药敏结果合理使用抗生素,减少耐药菌株的产生。
Objective: To understand the distribution and drug susceptibility of pathogenic bacteria in respiratory tract infection and provide the basis for rational clinical use. Methods: The composition ratio and susceptibility results of 457 pathogens isolated from sputum samples collected from inpatients from July 2005 to December 2005 were analyzed. Results: Of the 457 pathogenic bacteria isolated, 310 strains of G-bacteria (67.8%), 127 strains of G + -positive bacteria (27.8%), 20 strains of Candida albicans (4.4%), Klebsiella spp., Pseudomonas aeruginosa Escherichia coli and Staphylococcus aureus as the main pathogen. Conclusion: In the course of treatment, pulmonary tuberculosis patients should make rational use of antibiotics according to drug susceptibility results and reduce the generation of drug-resistant strains.
