The concentration- and time-dependent activity of myricetin in inhibiting the transition of reference H. pylori J99 and Tx30 strains from spiral to coccoid forms during serum starving conditions. The MIC of myricetin for both strains is equal to 160 µg/mL. The initial number of spiral forms (a 0-h time point) was 90% and 98% for H. pylori J99 and Tx30a, respectively. Results are presented as means ± standard deviations from three independent biological experiments. * Indicates statistically significant difference (p ≤ 0.05).
