Instead of using words, they use chemicals. Once these communication chemicals build up to a certain level, they affect gene expression and transcription. Antibiotic Resistance If you’ve been following along, you probably read about phage therapy, one of the novel ways to treat antibiotic resistance bacteria. As promised, I’m introducing another method: quorum sensing. The goal of quorum sensing research is to figure out how bacteria talk to each other….
