Antibiotics in swine feed encourage gene exchange

A study by Heather Allen and colleagues reveals that antibiotics in swine feed stimulate gene transfer among gut bacteria, increasing the risk of antibiotic resistance. The researchers found that prophages, segments of DNA encoding antibiotic resistance genes, underwent significant increases in induction when exposed to antibiotics.

New compound defeats drug-resistant bacteria

Researchers at Brown University have discovered a new compound that can defeat drug-resistant bacteria by blocking their efflux pumps. The compound, called BU-005, was found to inhibit the activity of two different families of drug-efflux pumps, one associated with Gram-positive bacteria and the other with Gram-negative bacteria.
