Successful response of metronidazole-resistant trichomonal vaginitis to tinidazole. A case report.

Treatment of metronidazole-resistant Trichomonas vaginalis infection is complicated by the lack of an effective alternative therapeutic regimen. Data on the susceptibility of the organism to metronidazole and other nitroimidazoles are important in managing intractable cases. A case of trichomonal vaginitis with true resistance to metronidazole that responded to treatment with tinidazole is reported.
