Precision DNA PCR-based Assay for Gardnerella vaginalis species in bacterial vaginosis

PAGE TITLE
Overview

PAGE SUMMARY
This new PCR-based companion diagnostic assay leverages genetic analysis to identify specific members of the Gardnerella vaginalis species and detects resistance to metronidazole, the current first-line treatment for bacterial vaginosis (BV). BV is a prevalent vaginal infection with ~30% annual incidence, high recurrence rates and limited treatment efficacy due to the genomic variation in G. vaginalis. Notably, G. vaginalis has recently been reclassified as a genus encompassing multiple distinct species, reflecting its considerable genetic diversity. Our researchers  have identified  multiple distinct genospecies and revealed that 5 species exhibit 100% resistance to metronidazole. By enabling rapid, accurate identification of resistant strains, this diagnostic assay supports personalized treatment strategies, reduces recurrence rates, and guides clinicians toward the most effective therapies.

Developed by Dr. Katherine Innamorati and Dr. Garth Ehrlich at Drexel University, this innovation integrates cutting-edge genomics with practical diagnostics to support precision medicine in reproductive health. This technology is ready for rapid and automated panel testing.
