卡他布兰汉球菌(CB菌)是一种常见于上呼吸道的革兰氏阴性双球菌,系非致病的共生菌。而目前发现CB菌已成为继流感嗜血杆菌和肺炎链球菌之后居第三位的引起下呼吸道感染的致病菌,并对抗生素有不同程度的耐药性。故通过回顾性分析探讨CB菌的呼吸系统感染特征。材料和方法复习巴塞罗那某医院2年间因呼吸道感染而住院者和医院内肺炎(NP)患者的病例,并查阅其呼吸道标本、血及胸水中分离获得CB菌的结果。凡有呼吸道感染症状(咳嗽、脓痰、胸痛、发热)和X线胸片肺浸润者诊断为肺炎;有症状而无胸片异
C. catarrhalis (CB) is a Gram-negative bacteria that is common in the upper respiratory tract and is a non-pathogenic commensal bacterium. At present, it has been found that CB bacteria have become the third cause of lower respiratory tract infection after Haemophilus influenzae and Streptococcus pneumoniae, and have different degrees of resistance to antibiotics. Therefore, through retrospective analysis of CB bacteria respiratory characteristics. Materials and Methods The cases of pneumonia (NP) hospitalized in hospital and hospital due to respiratory infection were reviewed in a hospital in Barcelona for 2 years, and their respiratory tract specimens were taken for examination. Results of CB strains obtained from blood and pleural effusion were obtained. Any symptoms of respiratory tract infection (cough, purulent sputum, chest pain, fever) and chest X-ray diagnosis of pulmonary infiltrates; symptoms without chest X-ray
