摘要 致病性弧菌检测方法主要是生化鉴定法,费时费力,而且对于生化反应不典型或生化反应极为相似的弧菌属无法准确鉴别,传统的生化鉴定法在大规模的病害调查过程和生产实践中无法做到快速准确方便。多重荧光PCR方法是在DNA分子水平进行微生物检测的一种新方法,根据样本中各种微生物的特异性基因对目标菌进行鉴定,可以稳定准确地在种属和菌株水平上鉴别微生物,弥补传统生化鉴定方法的缺陷。本研究通过优化多重荧光PCR方法体系,建立了水体中致病性弧菌的两个多重荧光PCR检测方法,该方法通过富集水体细菌,无需前增菌步骤,大大减少检测时间。实际工作中推广应用结果表明,多重荧光PCR方法检测7种弧菌,具有快速、准确度高、重复性好及敏感性高等特点。
