Ruhr University Bochum Apr 2 2026 Pathogenic bacteria often delay the activation of their virulence program until they are inside the host. Researchers have identified a new mechanism that controls this process. Some pathogens use temperature as a trigger and activate virulence only after entering the warmer environment of a host. A research team from Ruhr University Bochum, Germany, and the University of Münster, Germany, investigated how a diarrheal pathogen suppresses its virulence outside
