【摘要】 目的:了解肺癌患者并发呼吸道感染的菌群分布及药敏情况,为临床治疗提供依据。方法:将肺癌患者的痰标本进行培养,再进行生化试验、种类鉴定及药敏试验。结果:256例肺癌患者痰标本中分离出病原菌213株,其中真菌、表皮葡萄球菌、肺炎克雷伯氏菌的分离率居于前三位。分离菌株对临床常用抗菌药物表现不同程度的耐药性。结论:肺癌患者肺部感染的病原菌以真菌、G-细菌等条件致病菌占多数,它们对常用抗生素存在多重耐药,治疗时应根据药敏试验结果选择药物。更多还原

【Abstract】 Objective To investigate the bacteria sort and drug-sensitivity of respiratory infection with lung cancer patients.Methods Patients with lung cncer tool sputum general bacteria culture and positive culture results were examed the effect of biochemistry test and the drug-sensitivity.Bacterial sorts were identified.Results A total of 213 pathogen strains were isolated from 256 cases.The positive rate of fungi was the highest followed by Staph.epidermidisand and K.pneumoniae.The isolated pathogens resisted at different degrees to antibiotics which were used frequently in clinic.Conclusion Pathogen of respiratory infection in lung cancer patients is mainly fungi and Gram-negative bacteria which is multi-resistant.We suggest slecting antibiotic to therapy according to the result of drug-sensitivity test.更多还原
