摘要 回顾分析21例下呼吸道嗜麦芽窄食单胞菌感染的临床特点,采用纸片扩散法测定嗜麦芽窄食单胞菌的体外药物敏感性。结果17例患有慢性阻塞性肺疾病合并呼吸衰竭,11例患者免疫功能低下,14例曾接受侵入性诊治,均使用过广谱抗生素。临床表现为发热、咳嗽、咳痰,胸部X线多表现为双下肺斑片状阴影。药敏监测该菌耐药率>90%的有亚胺培南和头孢噻肟,>50%有氧哌嗪青霉素、头孢吡肟、奈替米星;而敏感率>50%者有左氧氟沙星、米诺环素、头孢哌酮/舒巴坦钠、复方新诺明。表明嗜麦芽窄食单胞菌下呼吸道感染多发生在有基础疾病、免疫功能低下者。患者临床表现中毒症状明显,部分出现肺实变和胸腔积液,细菌耐药现象严重,诊断与治疗有赖于细菌培养和药物敏感结果。
