Breakthrough Study Reveals Mechanisms of Bacterial Vaginosis

Researchers at UC San Diego School of Medicine uncover how bacteria disrupt the protective sugar chains in the vagina, potentially paving the way for easier diagnosis and better understanding of the condition.

• Researchers at the University of California San Diego School of Medicine have made a breakthrough in understanding bacterial vaginosis (BV), the most common vaginal condition in women aged 15 to 44.
• The study found that in BV, bacteria release enzymes called sialidases that partially subdue the protective sugar chains, or glycans, that cover the cells lining the vagina.
• The researchers were able to artificially induce some of the symptoms of BV in unaffected cells by treating them with carbohydrate-degrading enzymes produced in the lab.
• Levels of these enzymes were found to be higher in the vaginal fluid of women with BV compared to those without the condition.
• Further research is needed, but these findings could potentially make diagnosing BV easier and provide a better understanding of the condition's impact on vaginal health.
