摘要
目的：了解呼吸道感染的菌种分布及其耐药性监测，为临床合理用药提供依据。方法：对导致呼吸道感染患者的细菌进行培养分离及药敏试验，监测其对临床常用抗菌药物的耐药性。结果：从培养标本中检出568株致病菌，其阳性率为34.4%。呼吸道感染常见菌种为：铜绿假单胞菌237株，克雷伯菌属98株，大肠埃希菌51株，金黄色葡萄球菌34株，占总数的73.9%。对其他常用抗菌药物均有不同程度的耐药性。结论：呼吸道感染的主要病原菌是革兰氏阴性杆菌感染，多重细菌耐药情况较为严重；抗生素的选用应该依据感染菌种药敏实验分析的结果，细菌学检查是合理选用抗菌药物和减少细菌耐药的最佳方法。
Abstract
Objective: To investigate the distribution and drug resistance ofbacteria of respiratory tract infection, and provide the basis for clinical rational drug use. Method: to lead to patients with respiratory infection bacteria culture and sensitivity test, determination of the clinical antibiotic resistance. Results: thecultured from specimens of 568 pathogen detection, the positive rate was 34.4%.The common bacteria in respiratory tract infection: 237 strains of Pseudomonas aeruginosa, Klebsiel a pneumoniae 98 strains, 51 strains of Escherichia coli, 34 strains of Staphylococcus aureus, accounting for 73.9% of the total. Resistance to other antimicrobial agents have different levels of. Conclusion: the mainpathogenic bacteria of respiratory tract infection are gram negative bacil us infection, multiple bacterial drug resistance is serious; antibiotics should be selected according to drug sensitivity results of bacteria infection, bacteriologicalexamination is the rational use of antimicrobial drugs and the best way to reducebacterial resistance.
