Comparison of two different metronidazole regimens in the treatment of Gardnerella vaginalis infection with or without trichomoniasis

Gardnerella vaginalis infection confirmed by culture was treated either by a 2 g dose or divided doses of metronidazole in 100 and 200 female patients respectively. Both dosages were equally effective. We recommend a single dose of 2 g metronidazole in the treatment of Gard. vaginalis infection, particularly when association with trichomoniasis is confirmed or suspected.
