Conditions

Bacterial Vaginosis

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.

Interventions

OTHERMetronidazole

Women with Bacterial Vaginosis treated with Metronidazole for 5 days

Inclusion criteria

* Signed informed consent * Female gender * Over 18 years of age * Have a high probability for compliance with and completion of the study

Exclusion criteria

* Hypersensitivity to metronidazole --only applies to Group 2. * Post-menopausal defined as at least 12 consecutive months without menstruation * Treatment of BV in last 4 weeks * Clinically significant menstrual irregularities * Suspected presence of STDs or other vaginal infection * Pregnancy * Breast feeding * Participation in other clinical studies which could influence genitourinary tract microbiota * Substance abuse * Investigator believes that the participant may be uncooperative and/or noncompliant and should therefore not participate in the study

Design outcomes

Primary

MeasureTime frameDescription
Change in vaginal microbiota assessed with sequencingBaseline, at day 8, and at day 15Change 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

MeasureTime frameDescription
Vaginal microbiota/lactobacilli levels with Nugent scoringBaseline, at day 8, and at day 15Nugent 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 CanestestBaselineCanestest will be used to diagnose BV infection at baseline.
