Zones of growth inhibition for agar disk diffusion assays with antibiotics (disk diameter of 6.0 mm included)a

TABLE 2
  • a Each value represents the mean diameter of the inhibition halo ± standard deviation from three independent experiments (n = 3). Significant changes with regard to the WT strain are shaded. NS, not significantly different from the WT (P > 0.05); *, significantly different from the WT (P < 0.05); **, significantly different from the WT (P < 0.001).

  • b The presence of the Tetr marker in the BC010 strain increased tetracycline resistance in relation to the CAR strain, as expected.

  • c The presence of the Kanr marker in the BC020 strain increased kanamycin resistance in relation to the CIT strain, as expected.
