PCR-ESI/MS uses the mass-to-charge (m/z) ratio of a PCR amplicon to infer its base composition. The method uses primers targeted to conserved regions in the bacterial genome, as well as species-specific regions for accurate identification, and produces PCR products of different length and composition (Figure 1).
