In Vitro Testing of Trichomonas Vaginalis Drug Susceptibility: Evaluation of Minimal Lethal Concentration for Secnidazole That Correlates With Treatment Success

We determined the in vitro minimum lethal concentration of secnidazole and assessed the correlation with clinical susceptibility among Trichomonas vaginalis isolates obtained from 71 women, of whom 66 were successfully treated with this medication. A minimum lethal concentration ≤12.5 μg/mL correlated with clinical susceptibility in this study.
