The bacterium, Campylobacter coli, is one of the most common causes of diarrheal illness. New strains resist two drugs commonly used in treatment.
Findings point to possibility of new 'anti-evolution drugs' to keep hard-to-treat pathogens from arising.
In studies in humans and mice, bacteria confuse the metal gallium for a nutrient, and it works as a Trojan horse to destroy them.
The collisions promote mutations that may help bacteria adapt to stress

FOR IMMEDIATE RELEASE:
A new, rapid method is helping detect how bacteria sense and respond to changes in their environment. Bacterial can pick up external signals, which then relay to internal signaling pathways that direct their behavior.
