摘要: 联用VIDAS法(酶联免疫自动分析法)和API Listeria法;充分利用Vidas法的快速筛选性和APE List-eria的最终确定性检验及分类食品中李斯特氏菌属。实验结果显示,它可以检验并判断李斯特氏菌属中所有的菌种;其鉴定周期可从原来的10d缩减到5d,阴性结果的判断时间也从原来的72h,提前到现在的48h。该方法应用在115个实际样品中所得出的结果证明,联用方法较单一鉴定法快捷、有效。运用于食品中李斯特氏菌的检验和分类中,可以取得了令人满意的结果。

Abstract: To study an effective and fast method of detection for listeria spedes in food.The combined Vidas and API listeria method was used to detect the presence of listeria species and to diifferentia listeria species in fod samples .The results showed that the method was applicable to all species in listeria.Depending on this measure, it was shown that the whole detection time reduce to from 10d to 5d, and the negative result was obtained within 48h (24h shorter than conventional method. It was believed that this modified method was quickes and more effective than the separate method. Satisfactory results were obtained by using this modified measure in 115 actual samples.
