Combination effects of sub-inhibitory concentrations of punicalagin with the representatives of different classes of antimicrobials against MDR Enterobacteriaceae clinical isolates. A % increase in zone of inhibition resulted in a combination of 30 μg punicalagin/antimicrobial disc, 100 μg punicalagin/antimicrobial disc and 500 μg punicalagin/antimicrobial disc against S. typhimurium by agar disc diffusion assay, B % increase in zone of inhibition resulted in a combination of 30 μg punicalagin /antimicrobial disc, 100 μg punicalagin/antimicrobial disc and 500 μg punicalagin/antimicrobial disc against S. typhi by agar disc diffusion assay, C % increase in zone of inhibition resulted in a combination of 30 μg punicalagin/antimicrobial disc, 100 μg punicalagin/antimicrobial disc and 500 μg punicalagin/antimicrobial disc against E. coli by agar disc diffusion assay
