Bacterial Vaginosis Antibiotic Probiotic Study

To determine if the addition of either topical clindamycin or a topical probiotic/oestrogen combination, reduces recurrent rates of bacterial vaginosis (BV), when added to the current recommended therapy of seven days of the oral antibiotic metronidazole. Hypotheses 1. Combination antibiotic therapy of oral metronidazole with vaginal clindamycin will be more effective than oral metronidazole alone in the treatment of bacterial vaginosis. 2. Restoring normal vaginal acidity and healthy bacteria through replacement of Lactobacillus bacteria and topical oestrogen (in addition to oral metronidazole), will achieve higher rates of cure than current recommended therapy oral metronidazole alone.
