| 摘 要： | 本实验采用棉拭子涂抹采样法在相同面积、相同部位的物体表面上作反复涂抹不同次数的采样,以比较不同涂抹次数对检出细菌总数的影响。结果发现,二次涂抹采样细菌总数明显多于一次涂抹,二者比较差别显著(P<0.01);而三次涂抹与二次相比,则无显著差异(P>0.05)。所以,表面涂抹采样至少反复二次,方可获得较高捕获率。

| Abstract: | Using method of sampling by swabing with cotton swab, sampling by repeated swabing for different times on same area and same site of the surface of an article was carried out to compare the influences of swabing for different times on total bacterial count detected. The results showed that the total bacterial count obtained by swabing twice was significantly higher than that by swabing once, with significant difference (P< 0.01), while no significant difference was observed when swabing three times was compared with swabing twice (P>0.05). Therefore, surface swabing sampling should be repeated at least for two times in order to obtain high catching rate. |
