Abstract
目的:研究溶血性链球菌的环介导等温扩增(loop-mediated isothermal amplification,LAMP)检测方法,实现对溶血性链球菌的快速检测。方法:针对溶血性链球菌的scpA基因设计4条特异性LAMP内外引物进行LAMP扩增;优化扩增反应条件;采用包括溶血性链球菌在内的6种不同菌株进行LAMP的特异性检测,并酶切鉴定;对溶血性链球菌菌液以无菌水进行10倍系列梯度稀释后,进行LAMP扩增检测其灵敏度;将菌掺入牛奶样本并进行LAMP检测。结果:本法可快速灵敏地检测出溶血性链球菌,反应特异性高,检出限为16.7CFU/mL,而牛奶样本的检出限则达10CFU/mL。结论:LAMP法可用于食品溶血性链球菌的快速检测。
