Fighting Bacteria’s Strength in Numbers

Scientists at The University of Nottingham have opened the way for more accurate research into new ways to fight dangerous bacterial infections by proving a long-held theory about how bacteria communicate with each other.

Researchers in the University's School of Molecular Medical Sciences have shown for the first time that the effectiveness of the bacteria's communication method, a process called 'quorum sensing', directly depends on the density of the bacterial population. This work will help inform wider research into how to stop bacteria talking to each other with the aim of switching off their toxin production.
As some pathogenic organisms are increasingly resistant to traditional antibiotics, medical researchers around the world, including scientists at The University of Nottingham, are trying to find other ways of fighting infection. This new work involves using 'quorum quenching' compounds which interfere with bacterial signalling and disrupt their social lives.
