When bacteria like E. Coli face stressful times, a protein delivers a stress-response master regulator to help them survive and spread.

Water disinfection works well to kill or hamper the growth of most bacteria, but what about the genes that help them resist antibiotics?

Studying E. coli at neutral pH in the lab might not give us a full sense of their powers against antibiotics.

If antibiotics don't kill them all, bacteria lie in wait to return. New research suggests a solution.

The antibacterial chemical triclosan in many hand soaps, toothpastes, and even baby toys actually makes bacteria harder to kill.

A change at the hospital can safely cut the number of UTI tests in half. That could reduce the use of antibiotics and therefore drug-resistance.

Despite FDA warnings, many patients leave hospitals with prescriptions for powerful but dangerous antibiotics.

Staph bacteria are notoriously resistant to antibiotics, but new research homes in on the genes that let them stand up to copper.

Scientists have a new way to test how different environments within the body affect antibiotic performance.
