为了比较市面上销售的三种沙门氏菌显色培养基的质量与性能,保证检测结果的准确性,按照国家标准GB4789.28-2013和GB 4789.4-2016规定方法进行检验。检验得出CH、HK、HB三种显色培养基生长率分别为0.92、0.84、0.82,非目标菌定量结果均小于1,非目标菌定性结果能够显著区分菌落颜色,人工污染样品加入量在1~10CFU/m L时,三种培养基均能检出。三种显色培养基均满足培养基质量性能
In order to compare the quality and performance of the three Salmonella color-developing media marketed, the accuracy of the test results is verified according to the national standard GB4789.28-2013 and GB 4789.4-2016. The results showed that the growth rates of CH, HK and HB were 0.92, 0.84 and 0.82, respectively. The results of non-target bacteria were less than 1. The results of non-target bacteria could distinguish the colony color significantly. The amount of artificial contaminated sample was 1 ~ 10CFU / m L, three kinds of medium can be detected. Three color medium to meet the quality of the medium performance
