Identification of <i>Trichomonas vaginalis</i> 5-Nitroimidazole Resistance Targets

<i>Trichomonas vaginalis</i> is the most common non-viral sexually transmitted infection. 5-nitroimidazoles are the only FDA-approved medications for <i>T. vaginalis</i> treatment. However, 5-nitroimidazole resistance has been increasingly recognized and may occur in up to 10...

description <i>Trichomonas vaginalis</i> is the most common non-viral sexually transmitted infection. 5-nitroimidazoles are the only FDA-approved medications for <i>T. vaginalis</i> treatment. However, 5-nitroimidazole resistance has been increasingly recognized and may occur in up to 10% of infections. We aimed to delineate mechanisms of <i>T. vaginalis</i> resistance using transcriptome profiling of metronidazole (MTZ)-resistant and sensitive <i>T. vaginalis</i> clinical isolates. In vitro, 5-nitroimidazole susceptibility testing was performed to determine minimum lethal concentrations (MLCs) for <i>T. vaginalis</i> isolates obtained from women who had failed treatment (<i>n</i> = 4) or were successfully cured (<i>n</i> = 4). RNA sequencing, bioinformatics, and biostatistical analyses were performed to identify differentially expressed genes (DEGs) in the MTZ-resistant vs. sensitive <i>T. vaginalis</i> isolates. RNA sequencing identified 304 DEGs, 134 upregulated genes and 170 downregulated genes in the resistant isolates. Future studies with more <i>T. vaginalis</i> isolates with a broad range of MLCs are needed to determine which genes may represent the best alternative targets in drug-resistant strains.
