Fig 6.

Bar charts depict biofilm eradication by 5-iodoindole across six isolates at concentrations from 1 MIC to 1/64 MIC. Significant reductions in OD₅₇₀ are observed at all doses, with consistent antibiofilm activity at lower concentrations.

Biofilm eradication of six XDRAB isolates (A19, A35, A43, A50, A46, and A49) by 7-hydroxyindole at sub-MIC levels (n = 6, x- ± s; **P < 0.01 versus none group).
