呼吸道感染病原菌分布及耐药性分析

Analysis on Distribution and Drug Tolerance of Respiratory Infection Bacteria

目的：明确呼吸道感染病原菌的构成及耐药情况，为临床合理用药提供依据。方法：对痰培养标本进行细菌培养，用VITEK仪鉴定细菌；药敏试验采用K—B法。结果：呼吸道感染前五种病原菌分别为白假丝酵母菌、铜绿假单胞菌、肺炎克雷伯肺炎亚种、鲍曼不动杆菌及大肠埃希菌。革兰阴性杆菌对亚胺培南、美南培南、阿米卡星及头孢哌酮较敏感，鲍曼不动杆菌有极强的耐药性。革兰阳性球菌对万古霉素、替考拉宁敏感性为100％。结论：分析呼吸道感染细菌的分布及耐药性，可指导临床医生用药。

Objective： To make sure the construction as well as drug tolerance of respiratory infection pathogenic bacteria to offer basis for clinical drug use. Methods： Assessing bacteria with VITEK and using K-B to test drug sensitivity. Results： Gram-negative bacteria is sensitive to imipenem, amikacin and cefoperazone. Baumanii has showed high drug tolerance. The sensitivity rates of gram-positive bacteria to vancomycin and teicoplanin are 100%. Conclusion： The analysis of distribution and drug tolerance of respiratory infection bacteria can help guide the clinical drug use.
