A convenient and effective microtechnic of bacteria numeration in sputum has been used and its results are presented, considering the accompanying clinical data. One has therefore been able to appreciate the signification of the number and prevalance of bacteria isolated in lower respiratory tract infections: 1) The concentration of 10(7) bacteria/ml is a useful critical value, but it does not mean either virulence or lower limit of pathogenicity. 2) The importance of the predominance of a bacterial strain is an essential parameter in quantitative analysis. 3) The interpretation of the bacteriological results can only be made after thoroughly examining the cytology, the clinical infection symptoms, the anamnestic data, and considering the possibility of an antibiotic therapy preceding the test.
我们采用了一种便捷有效的痰液细菌计数微观技术，并结合相关临床数据展示了其结果。因此，人们能够认识到下呼吸道感染中分离出的细菌数量和流行情况的意义：1）每毫升10⁷个细菌的浓度是一个有用的临界值，但这并不意味着毒性或致病性的下限。2）一种细菌菌株占优势的重要性是定量分析中的一个关键参数。3）只有在全面检查细胞学、临床感染症状、既往病史数据，并考虑到检测前进行抗生素治疗的可能性之后，才能对细菌学结果进行解读。
