PCR products of the antimicrobial resistance genes (a, b, c and d) identified in S. thoraltensis visualized on agarose gel electrophoresis. The expected molecular size of amplified DNA: 430 bp for Pbp1A gene (a), 732 bp for vanA gene (b), 425bp for ermB gene (c) and 1395 bp for optrA gene (d). Lane 1-4: samples, Lane (L): DNA ladder, Lane (+ve): positive control and Lane (-ve): negative control.
