A comparative study of two air-bacteria counting machines, MK II (Casella, London) and R.B. (Joubert, Lyon) was carried out. Pre-operation air samples from operating rooms were drawn by the two machines working simultaneously. The results from the two machines are similar, however the RB machine is the more sensitive of the two machines. Moreover, an old operating room without filtrated air had a significantly higher air bacteria contamination (m = 199 +/- 173 bacteria/m3) than a new one with filtrated air (m = 40 +/- 36 bacteria/m3). Samples from laminar air flow (m = 1,3 +/- 1,5 bacteria/m3) were examined as test studies. Working methods and results of air bacteria counts are studied.
对两台空气细菌计数仪，即MK II（伦敦卡塞拉公司）和R.B.（里昂朱伯特公司）进行了一项对比研究。手术室术前空气样本由这两台同时运行的仪器采集。两台仪器的结果相似，但RB仪器在这两台仪器中更为灵敏。此外，一个没有空气过滤装置的旧手术室的空气细菌污染水平（中位数=199±173个细菌/立方米）显著高于一个有空气过滤装置的新手术室（中位数=40±36个细菌/立方米）。作为测试研究，对层流空气样本（中位数=1.3±1.5个细菌/立方米）进行了检测。对空气细菌计数的工作方法和结果进行了研究。
