Thirty-six transtracheal aspirates from 34 patients with chronic bronchitis and bronchiectasis were examined bacteriologically. Bacteria were isolated from 30 aspirates, 23 of which yielded pure culture. Anaerobic bacteria were found in three aspirates, all in pure culture. This preliminary report indicates a greater complexity of the microbial flora in chronic bronchitis and bronchiectasis than hitherto appreciated.
对34例慢性支气管炎和支气管扩张患者的36份经气管吸出物进行了细菌学检查。从30份吸出物中分离出细菌，其中23份培养出纯培养物。在3份吸出物中发现了厌氧菌，均为纯培养物。这份初步报告表明，慢性支气管炎和支气管扩张中的微生物菌群比迄今所认识到的更为复杂。
