Surprising new theory on antibiotic resistance

A surprising new theory developed at the University of Nebraska Medical Center (UNMC) in Omaha, Nebraska, suggests that some bacterial cells act as "suicide bombers" in cell communities, with the altruistic intention of dying for the common good - and in the process, strengthening other cells that then become resistant to antibiotic drugs.

Researchers develop technique to concentrate, manipulate and separate a wide class of swimming bacteria

The technique is based on the transmission of tiny electric current in a very thin film sample cell containing a colony of bacteria. The current produces electrolysis that changes the local pH level in the vicinity of the electrodes.
