Molecular Characterization and Phylogenetic Analysis of Listeria monocytogenes Isolated from Milk and Milk Products in Kaduna, Nigeria

Figure 1

Agarose gel electrophoresis showing electrophoretic mobility of PCR products obtained following amplification of the 16S rRNA gene (938 bp) and listeriolysin O encoding gene (hly A) (702 bp) from different Listeria monocytogenes isolated from raw milk and milk products. Lane M: 100 bp ladder; Lane 1: positive control (Listeria monocytogenes ATCC 19155); Lane 3: Listeria monocytogenes (LM) isolate ZKMM84; Lane 5: LM SGHR 30; Lane 6: LM SGSK1; Lane 9: LM ZKJR56; Lane 10: LM SGHR39; Lane 11: LM ZKMR75; Lane 12: LM SGMM87; Lane 13: LM SGHR15; Lane 14: LM LMFR162, corresponding to 938 bp and 702 bp amplicons.
