A multiplex oligonucleotide ligation-PCR (MOL-PCR) assay is a valuable high-throughput technique for the detection of bacteria and viruses, for characterization of pathogens and for diagnosis of genetic diseases, as it allows one to combine different types of molecular markers in a high-throughput multiplex assay. A MOL-PCR assay starts with a multiplex oligonucleotide ligation reaction for detection of the molecular marker, followed by a singleplex PCR for signal amplification and analysis of the MOL-PCR products on a Luminex platform. This last step occurs through a liquid bead suspension array in which the MOL-PCR products are hybridized to MagPlex-TAG beads.

In this chapter, we describe the complete procedure for a MOL-PCR assay for subtyping of Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) and its monophasic variant S. 1,4[5],12:i:- from DNA isolation through heat lysis up to data interpretation through a Gödel Prime Product. The subtyping assay consists of 50 discriminative molecular markers and two internal positive control markers divided over three MOL-PCR assays.
