Characterization and Antimicrobial Susceptibility Patterns of Listeria monocytogenes from Raw Cow Milk in the Southern Part of Ethiopia

Figure 2

PCR detection of Listeria from raw milk samples. Lanes 1–7 contain the Listeria specific 16S rRNA gene without having the virulent genes, whereas lanes 8 to 18 contain the hlyA and iapA virulent-associated genes with the amplicon size of 456 bp and 131 bp, respectively. Lane M, DNA molecular weight marker (100 bp); Lane 1, negative control; Lane 19, positive control.
