Abstract

A real-time loop-mediated isothermal amplification (RealAmp) assay for the detection of Listeria was developed. The RealAmp assay, using primers specific for the hemolysin-encoding hlyA gene, was verified using Listeria monocytogenes strains (n = 58) from different regions of the world. Both the sensitivity and specificity of the RealAmp assay were high. The RealAmp assay could detect 103 CFU ml-1 within 30 min. A comparative evaluation of the RealAmp assay, the API Listeria assay, and the real-time PCR assay revealed that the RealAmp assay is simpler, faster, and has a higher specificity than the other two assays.
