Dr Lai noted that CVM can be thought of as a 'biological condom' which could potentially be reinforced by altering a woman's vaginal microbiota.
'If we could find a way to tilt the battle in favor of L. crispatus in women, then we would be increasing the barrier properties of their CVM, and improve protection against STIs,' he said.
Richard Cone, a biophysicist at Johns Hopkins University in Baltimore and another author on the study, is working on solutions that might deliver a sustained release of lactic acid to the vagina, which would encourage L. crispatus to thrive.
The study was published in mBio, an online open-access journal of the American Society for Microbiology. Hopefully we really are one more step to find the cure, let's hope for the best!
