摘要: 目的 建立一种啮齿类螺杆菌(helicobacter rodentium)的快速检测方法。方法 根据啮齿类螺杆菌16S rRNA的基因序列设计了1对特异性引物, 建立了啮齿类螺杆菌 SYBR Green Ⅱ荧光定量PCR检测方法。结果 在102拷贝/µL~107拷贝/µL浓度范围中标准曲线循环阈值与模板浓度呈良好的线性关系。该方法特异性良好, 仅对啮齿类螺杆菌产生特异性扩增, 且灵敏度可达到30拷贝/µL, 组内和组间的变异系数均小于2%,具有良好的重复性。结论 建立了SYBR Green Ⅱ荧光定量PCR检测啮齿类罗杆菌的一种方法。

Abstract: Objective To establish a rapid detection method for helicobacter rodentium.Method A pair of specific primers was designed according to the gene sequence of Helicobacter rodentium 16S rRNA.The method of SYBR Green Ⅱ real-time PCR was established.Results The standard curve cycle threshold had a good linear relationship with the template concentration in the range of 102 copies /µL to 107 copies /µL concentration.This method has good sensitivity,only specific amplification of Helicobacter rodentium,could detect 30 copies /µL,the coefficient of variation (CV) was less than 2% within and between groups with good reproducibility.Conclusion The method of SYBR Green Ⅱ real-time PCR was established for the identification of Helicobacter rodentium.
