title: Comparative in vitro cytotoxic effects of ornidazole, metronidazole and ciprofloxacin against Trichomonas vaginalis trophozoites.
abstract: A strain of Trichomonas vaginalis, isolated from a patient complaining of vaginal discharge, was incubated and cultivated to compare the in vitro effects of ornidazole, metronidazole and ciprofloxacin on T. vaginalis trophozoites in terms of minimal inhibition concentrations (MICs) and minimal lethal concentrations (MLCs). MIC levels at 24 hours for ornidazole, metronidazole and ciprofloxacin were 50 mg/mL, 50 mg/mL, and 750 mg/mL. Corresponding MLC levels were the same. In this in vitro study, ornidazole was found to be the most effective drug among 3 drugs tested against T. vaginalis trophozoites in terms of MIC and MLC levels. It is interesting to note that ciprofloxacin, although not as effective as the others, also had some cytotoxic effect on T. vaginalis trophozoites.
