Inhibition of pneumococcal capsule by purified rhodomyrtone. Effects of purified rhodomyrtone at different concentrations including 0.5 × MIC (Inline graphic), 0.25 × MIC (Inline graphic), 0.125 × MIC (Inline graphic), and 0.063 × MIC (Inline graphic) on percentage of pneumococcal capsule (A) and growth (B), compared with control (1% DMSO). The relative percentage of capsule formation was defined as: (mean A640 of treated cells/mean A640 of control) × 100. Capsular illustration by transmission electron microscopy of S. pneumoniae TIGR4 cells before (C) and after exposure to 0.5 × MIC purified rhodomyrtone (D). *p < 0.05.
