Abstract | The invention discloses a quick detection method by using an interior label and taking a sigD/sigE gene of salmonella as a target through reverse transcription fluorescent quantitation PCR (Polymerase Chain Reaction). In the quick detection method, an RNA (Ribonucleic Acid) interior label obtained by PCR amplification for three times is composed. In addition, the invention further provides a corresponding kit and application. The method disclosed by the invention can be widely applied to the fields such as research of laboratories, food safety and health and hygiene. The phenomenon of false negative missed detection can be avoided, so that the PCR amplification is effectively monitored; in addition, the detection specificity of salmonella is strong, so that dead bacteria and live bacteriacan be effectively distinguished; the quickness and high detection sensitivity are obtained; and the method can be applied to high-throughput screening of the salmonella in the food. |
