老年患者痰标本病原菌分布及耐药监测

The Distribution and Drug Resistance of Pathogenic Bacteria in Sputum Specimens

目的:了解老年患者痰标本常见病原菌种类及耐药性,为合理用药提供依据。方法:对1071份痰标本运用WHO-NET5.4软件进行回顾性统计和分析。结果:共分离病原菌602株:真菌91株(15.11%)、G-菌385株(63.85%)、G+菌126株(20.93%)。结论:老年人下呼吸道感染以G-菌常见,此外真菌也有较高的感染率。

Objective:To investigate the distribution of pathogenic bacteria and its drug resistance in senile patients with lower respiratory tract infection to guide rational drug use.Methods:The 1071 sputum specimens were collected and were statistically analyzed with WHO-NET 5.4 software by using the retrospective investigation method.Results:602 pathogenic strains were isolated,including 385 strains of Gram-negative bacilli(63.85%);Gram-positive bacteria were 126 strain(s 20.93%);91 strains were fungi(15.11%).Conclusion:Gram-negative bacilli and fungi are the major pathogens in senile patients with lower respiratory tract infection.Antimicrobials should be selected reasonably based on the results of drug susceptibility test.
