Intimate part of a woman's body with roses

In healthy women there are several kinds of vaginal microbiota (the microorganisms in a particular site), mostly dominated by Lactobacillus. The disruption of the vaginal microbiota may cause conditions like bacterial vaginosis.

Vaginal bacteria that are important for a healthy vaginal system may have added benefits of inhibiting the sexually transmitted Zika virus and herpes simplex virus-2, a new study suggests.

Mix of bacteria

“The human vagina has a wide array of bacterial species living in communities called the microbiome; these are very important for a woman’s health,” study lead author Megan Amerson said. She’s a doctoral student at the University of Texas Medical Branch at Galveston.

The researchers ran a series of laboratory experiments to see how different bacterial environments affected how well the viruses survived and replicated. Amerson’s team used transplanted vaginal microbiome samples from healthy donors.
