Study on Loop-Mediated Isothermal Amplification Assay for Detection of Salmonella in Meat Products

A novel nucleic acid amplification method, termed Loop-mediated Isothermal Amplification (LAMP), which amplifies DNA with high specificity, efficiency, andrapidity under isothermal conditions using a set of four specially designed primers and a DNA polymerase with strand displacement activity, may be a valuable tool for the rapid detection of infectious diseases. This study designed two pairs of gene-specific primers of conservative
invA
gene, this study establish the LAMP assay of detection of
Salmonella
successfully, and detection of
Salmonella
in meat products by LAMP, which is high specifical and sensitive, also save time for the detection of pathogens in food. So it provides the technology platform and technical support for the general detection organizations to promote this technology.
