mm = diameter of zone of inhibition around the antibiotic discs; ZOI zone of inhibition; ND Not Detected; R Resistant (0 to 15 mm), I Intermediate (15.01 to 20.00), S Sensitive (more than 20 mm). Values are represented in mean ± SD with three independent determinations (n = 3) from each sample. Values bearing different superscripts in each cell differ significantly from each other as evident by Tukey’s test at P ≤ 0.05
