Treatment of Hemophilus vaginalis vaginitis.

Four antimicrobial agents (triple sulfa cream, doxycycline, ampicillin, and metronidazole) were studied by double-blind techniques to determine their effectiveness in the treatment of Hemophilus vaginalis vaginitis, documented by vaginal culture in 96 patients. Cure was confirmed by negative vaginal cultures 7 weeks after the start of therapy. Metronidazole proved to be effective in 20 of 22 couples (90.9%) treated. Sulfa cream, doxycycline, and ampicillin were effective in 47.8 to 63.6% of patients treated.
