  1. Data were presented as means ± SD (n=3), and value in the same line with different superscript letters denotes significant difference (p<0.05).
  2. Tested at a concentration of 6.0 mg per disc.
  3. DD disc diameters of the inhibition zones, including the diameter of the filter paper disc (6 mm), MIC minimum inhibitory concentration, MBC minimum bactericidal concentration, NI no inhibition.
