Gel electrogram of SodA gene-specific primer-based PCR products of normal colorectal tissues experimentally inoculated with three PSBS strains (PSBS-tissue) and six NSBS strains (NSBS-tissue). PSBS-tissues (lanes A-C) were CIP 105428, CIP 105683, and CIP 105070, respectively while NSBS-tissues (lanes D-I) were CIP 108103, CIP 56.41, CIP 102504, ACM 3539, CIP 76117, and ATCC 25285, respectively. PSBS-tissues, but not NSBS-tissues samples, yielded single band at 408 bp. The used ladder was QIAGEN GelPilot DNA Molecular Weight Marker.
