比较了国产及进口两个品牌的菌落总数及大肠菌群测试片与传统国标法计数结果的符合度,并对干片产品较之传统培养法的菌落特征辨识度、操作简便性及检测成本等关键指标进行对比评判。结果显示,三者在所测两种基本卫生指标的计数结果上呈现高度平行性(p>0.05),快速纸片法可简化程序但成本高,使用者可根据实际工作需要结合使用;而在菌落辨识度上进口纸片呈现显著优势,尤其适用于复杂基质样本的检测。
The comparisons of the colony counts of both domestic and imported brands and the colony counts of coliform bacteria with those of traditional national standard methods were made and the characteristics of colony identification, ease of operation and detection cost of dried products compared with traditional culture methods were compared Comparative evaluation of key indicators. The results showed that the three were highly parallel (p> 0.05) on the counting results of the two basic health indicators tested, the fast paper method could simplify the procedure but the cost was high, and users could use it in combination with actual work needs. The colony recognition of imported paper presents a significant advantage, especially for the detection of complex matrix samples.
