An example of the outcome of the multiplex PCR reaction for determining the genes coding macrolide resistance ermA (139 bp), ermC (190 bp) and msrA (163 bp). Legend: Lane 1 –marker (Eurx Perfect TM 100 bp DNA Ladder ); 2 – 17 studied samples; 18 – positive control reference msrA W2/28; 19 – positive control reference ermC W2/55; 20 – negative control.
