下呼吸道感染病原菌及耐药性的探讨

Pathogens and resistance of lower respiratory tract infection

目的探讨下呼吸道感染的病原菌及耐药性特点。方法对274例下呼吸道感染患者的下呼吸道分泌物进行细菌培养和药敏试验。结果痰标本中检出病原菌239株,最主要为鲍曼不动杆菌和铜绿假单胞菌;其中革兰阳性杆菌和革兰阴性杆菌都显示出了较高的耐药性。结论下呼吸道感染的病原菌的耐药情况较为普遍,应合理使用有效的抗菌药物。

Objective To explore the lower respiratory tract infection pathogens and drug resistance characteristics. Meth- ods A total of 274 patients with lower respiratory tract infections were taken with bacterial culture and drug susceptibility testing. Results A total of 239 pathogens were detected Acinetobacter baumannii and Pseudomonas aeruginosa. G and G- bacteria showed a higher resistance. Conclusion respiratory tract infection pathogens resistance is more common, rational use of effective antimicrobial agents is necessary.
