Combination therapy rids common infection from implanted medical devices

A new combination therapy has been developed to target fungal infections in implanted medical devices, effectively clearing biofilm-based infections. The therapy inhibits a protein called Hsp90, rendering antifungals effective against biofilms, offering hope for patients with device-related infections.
