Published in Nature Microbiology, a study in mice finds that the microbial basis for urinary tract infections can include localized epigenetic alterations that make additional infections more likely.
The world of epigenetics—where molecular 'switches' attached to DNA turn genes on and off—has just got bigger with the discovery by a team of scientists from the University of Cambridge of a new type of epigenetic modification.
