呼吸系统疾病患者痰培养及药敏结果分析

目的分析我院呼吸系统疾病患者细菌感染的趋势及耐药情况。方法对258例呼吸道患者的痰标本以培养和用最低抑菌浓度(MIC)方法行药物敏感测定。结果从258例呼吸系统患者痰标本中共检出细菌309株,革兰阴性杆菌占40.8%,革兰阳性球菌占3.8%,念珠菌占55.4%;念珠菌感染有上升趋势;排在前五位的分别是鲍曼复合不动杆菌、铜绿假单胞菌、大肠埃希菌、肺炎克雷伯杆菌及阴沟肠杆菌;主要细菌对常用的抗生素存在不同程度耐药。结论临床上应重视呼吸道患者的病原学检测及耐药问题,以合理使用抗生素提高疗效。

Sputum culture and drug sensitivity analysis of patients with respiratory system diseases

Objective To analyze the trends of bacterial infection and drug resistance in patients with respiratory system diseases. Methods 258 sputum samples were cultured and the drug sensitivity was tested by the minimum inhibitory concentration （MIC） method. Results 309 bacterial strains were isolated from the samples. Gram negative bacilli accounted for 40.8% , gram positive bacilli accounted for 3.8% , and Monilia accounted for 55.4% , which had the ascending trend. The top five kinds of bacteria were baumanii, Pseudomonas aeruginosa, Escheriehia coli, Klebsiella pneumoniae and Enterobaeter cloacae. The main bacteria all showed different degrees of resist- ance to the commonly used antibiotics. Conclusion The pathobiology assay test and drug resistance of patients with respiratory systemdiseases should be paid more attention clinically to improve the curative effect by using antibiotics reasonably.
