机体抵抗力的降低,常伴随着寄生于上呼吸道的常居菌向呼吸道下部侵入的活跃;同时也可发生微生物的协同作用。在慢性肺炎时,痰是检查微生物最常用的标本。在鉴别肺炎的微生物种类时,检查支气管内容物更为有用。作者对414例患有各种慢性肺疾患(慢性肺炎、肺炎并发支气管扩张、脓肿形成和恶性肿瘤)病人的支气管内容物进行了微生物丛的检查。将支气管吸出物以2000转/分离心15分钟后,取沉淀物涂片,作革兰氏染色。为了增菌,将支气管吸出物接种在糖肉汤、以及血琼脂、沙保弱氏等培养基上。并对分离的纯培养物作了生物学性状的鉴定。
Reduced body resistance, often accompanied by the parasites in the upper respiratory tract inhabitants of lower respiratory tract invading active; also can occur synergies of microorganisms. In chronic pneumonia, sputum is the most commonly used specimen for examining microorganisms. It is more useful to check the contents of the bronchus when differentiating the type of pneumonia. The authors performed a microbiological examination of the bronchial contents of 414 patients with various chronic lung conditions (chronic pneumonia, pneumonia complicated with bronchiectasis, abscesses and malignancies). The bronchial aspirate was centrifuged at 2000 rpm for 15 minutes and the pellet was smeared for Gram staining. In order to increase the bacteria, the bronchial aspirate was inoculated in sugar broth, and blood agar, Sabouraud weakness and other media. The biological characteristics of the isolated pure culture were identified.
