  • a Wells were cut in nutrient agar, test agent was added to each well and overlaid with a lawn of S. flexneri. The starting concentrations of the test agents were as follows: AV, 450 mg/ml; AVG, 90% (vol/vol); AMP and NAL, 512 μg/ml.

  • b AVG, Aloe Vera Gel (Forever Living Products).

  • c Significant inhibition compared with untreated wells (P < 0.001).

  • d Significant inhibition compared with untreated wells (P < 0.05).

  • e -, no inhibition detected.
