Arm Description
Metronidazole 400 mg 3 times daily for 5 days for Bacterial Vaginosis (BV) infection
Healthy women without Bacterial Vaginosis and without treatment
Outcomes
Primary Outcome Measures
Change in vaginal microbiota assessed with sequencing
Change in vaginal microbiota is assessed with sequencing at 3 time points (baseline, at day 8 and at day 15 time points post antibiotic treatment.)
Secondary Outcome Measures
Vaginal microbiota/lactobacilli levels with Nugent scoring
Nugent scoring is used for the evaluation of the vaginal microbiota at baseline, at 8 and 15 day time points post antibiotic treatment.
Diagnosis of BV with "Canestest"
"Canestest" will be used to diagnose BV infection at baseline.

5. Study Description
Brief Summary
The study will assess vaginal microbiota levels before and after antibiotic treatment in females infected with Bacterial Vaginosis (BV).
Detailed Description
This method validation study will endeavour to obtain evidence for:
Recruitment methodology effectiveness
The usefulness of the "Canestest" test as a screening tool
The time required for the vaginal microbiota (particularly Lactobacillus count) to return to normal after treatment of BV infection with metronidazole.
The time required for the Nugent Score to return to normal after treatment of BV infection with metronidazole.
