[摘要]目的探讨下呼吸道感染患者痰菌的临床检验结果。方法便利选择2017年6月—2018年9月期间该院收治的下呼吸道感染患者196例为研究对象，按照常规方法采集痰液标本，均行细菌培养和涂片检查，对患者的病原菌细菌类别和耐药情况进行分析。结果该组的196例患者中，共分离出189株病原菌，其中112株为革兰阴性菌，占59.26%，50株为革兰阳性菌，占26.46%，27株为真菌，占14.28%;经药敏试验显示，鲍曼不动杆菌对头孢克肟、环丙沙星以及左氧氟沙星具有一定的耐药性;铜绿假单胞菌对环丙沙星、亚胺培南以及左氧氟沙星耐药;大肠埃希菌对头孢曲松、左氧氟沙星、复方新诺明以及头孢唑林耐药;肺炎克雷伯菌对头孢曲松、复方新诺明以及左氧氟沙星耐药。结论下呼吸道感染患者的病原菌以革兰阴性菌为主，通过行药敏试验，有助于选择合适的药物，提高治疗效果。
