Early Diagnosis of Premature Births by Analysis of the Vaginal Microbiota

Any pregnant woman attending the obstetrics department of Clermont-Ferrand University Hospital who requires a vaginal swab (VS) for her clinical situation (routine care) will be offered the study. If the participant accepts, the usual swab will be doubled and performed simultaneously in a single procedure using two swabs. The first swab will be sent to the laboratory and used for diagnosis. The second swab will be used for microbiota analysis.
