Inhibition of Streptococcus mutans biofilms with bacterial-derived outer membrane vesicles
Abstract Background Biofilms are microbial communities surrounded by a self-produced extracellular matrix which protects them from environmental stress. Bacteria within biofilms are 10- to 1000-fold more resistant to antibiotics, making it challenging but imperative to develop new therapeutics that...
