【摘要】：目的探讨二级筛孔撞击式空气微生物采样器与六级筛孔撞击式空气微生物采样器对空气中细菌总数的测定结果的差异性。方法在相同的地点和时间,分别使用二级和六级筛孔式空气微生物采样器对选定实验室、医院门诊大厅和洁净手术室的空气进行采样,采样流量为28.3 L/min,采集时间为15 min,在37℃生化培养箱分别培养24 h、48 h和72 h后观察结果,并对结果进行统计分析。结果二级与六级筛孔式空气微生物采样器在相同环境相同采集时间并在相同培养条件下的集菌量均无显著性差异(P0.05)。结论应根据不同监测目的选择适合的采样器,二级筛孔式空气微生物采样器适用于测定空气中细菌总数采样,六级筛孔式空气微生物采样器则更适用于空气细菌粒径大小及分布研究使用。
[Abstract]:Objective to study the difference of the determination results of bacteria in the air between the two stage sieve hole impinging air microorganism sampler and the six stage screen hole impinging air microbial sampler. Methods at the same time and at the same time, the air samples of selected laboratory, hospital outpatient hall and clean operating room were sampled by two and six stage sieve air microorganism sampler, respectively. The sampling flow rate was 28.3 L / min and the sampling time was 15 min. The results were observed after 24 h and 72 h culture in 37 鈩，
