Branhamella (Neisseria) catarrhalis was identified as a probable respiratory tract pathogen in seven patients, four with pneumonia and three with bronchitis. Five of the B. catarrhalis isolates produced beta-lactamase. Production of beta-lactamase correlated with penicillin resistance by the standardized disk diffusion method and also with high minimal inhibitory concentrations of penicillin for the two strains which were tested.
卡他布兰汉菌(奈瑟菌属)被确定为7例患者可能的呼吸道病原体,其中4例患有肺炎,3例患有支气管炎。5株卡他布兰汉菌分离株产生β-内酰胺酶。通过标准纸片扩散法,β-内酰胺酶的产生与对青霉素的耐药性相关,并且对于所测试的两株菌株,还与青霉素的高最低抑菌浓度相关。
