Scientists Discover How To “Hack” Bacterial Conversations To Prevent Gum Disease Like all living things, bacteria adapt in order to survive. Over time, many have become resistant to widely used antibiotics and disinfectants, creating growing challenges for healthcare and sanitation. At the same time, a large portion of bacteria are helpful and play essential roles in human health. This raises an important question: could shifting the behavior of bacteria inside the body help prevent disease and improve health outcomes? The hidden language of oral microbes Bacteria communicate constantly. Hundreds of species in the human mouth send and receive chemical messages in a process called quorum sensing. Many rely on signaling molecules known as N-acyl homoserine lactones (AHLs) to exchange information. Researchers in the College of Biological Sciences and the School of Dentistry at the University of Minnesota set out to explore how oral bacteria use these signals and whether this communication could be altered to stop plaque from forming and support a healthier oral microbiome. Their findings, published in the journal npj Biofilms and Microbiomes, point to possibilities that could reshape future medical treatments. Source:SciTechDaily @EverythingScience
