摘要
快速检测猪肉中单核细胞增多症李氏菌的ＰＣＲ试剂盒与分离培养法平行检测１５６份猪肉样品，结果ＰＣＲ的阳性率为５．８％，分离培养法的阳性率为３．８％，两者符合率为９７％。实验证明，该试剂盒具有良好的特异性和可重复性，可测出样品中至少３２ＯＣＦＵ细菌，并在２ｄ内取得结果，具有推广应用价值。
A kit of rapid PCR for detection of L, monocytogenes has been developed and used todetectthe bacteria in pork samples in paralell with the routine culture method with the result that positive ratewas 5.8%for the former and 3.8% for the latter,and as few as 320 CFU bacteria could be detected。No significant differences were found between the results of both methods(p >0. 05).The results alsoshowed that the rapid PCR kit had good specificity and reproductivity,and required less than 48h to gofrom sample to a final result.It is concluded that the rapid PCR kit is applicable to detect L。monocytogenes in pork。
