经纤支镜下呼吸道采样定量培养厌氧菌37例分析

Quantitative culture of anaerobes colleted in lower respiratory tract by bronchofibroscope

为了解肺部感染对下呼吸道厌氧菌的细菌状态及其与临床诊断及需氧菌间的关系，对３７例肺部疾病患者（感染组３７例，非感染组７例）用纤支镜防污染标本刷（ＰＳＢ）采集标本，进行了厌氧菌及需氧菌定量培养。结果：３７例中细菌培养阳性３３例（８９．１９％）；感染组中厌氧菌需氧菌同时阳性２２例（７３．３３％）；在３０例肺部感染病人中，２３例厌氧菌菌量≥１０￣３ｃＦｕ／ｍｌ。提示厌氧菌细菌定量经纤支镜采样有助于下呼吸道感染的诊断和治疗。

In ordre to investigate the seate of anaerobes in lower respiratory tract and the relationship between clinical diagnosis and aerobes quntitative cultures of anaerobic and aerobic hacteria were performed in 37 patients with lung diseases (30 with infection, 7 without infection),from whom the samples were colllected using bronchoscopic protected catheter brush, Results that 33 cases were positive for bacterial cuiture of 30 cases of lung infection, 22 (73. 33%) were positive for both anaerobes and aerobes,and 23 had high colony counts (103 cFu/ml). It is indicated that quantitative culture of anaerobes collected by bronchofibroscope is usful in diagnosis and treatment of lower respiratory tract infection.
