Several studies have observed that use of a conventional PCR protocol with primers LM1 and LM2 for the identification of the hlyA gene of Listeria monocytogenes generates non-specific PCR amplifications and false positives. For this reason, in this study we provide a modified PCR protocol that improves the specificity of the results obtained with LM1 and LM2 primers.
