Mechanism uncovered behind Salmonella virulence and drug susceptibility

Researchers have discovered a novel mechanism in Salmonella that affects is virulence and its susceptibility to antibiotics. The mechanism changes the bacteria's production of proteins in a previously unheard of manner. It allows Salmonella to selectively change its levels of certain proteins to respond to inhospitable conditions. Although the mechanism had not been recognized before, scientists found evidence of a similar mechanism in all five kingdoms of life. The mechanism appears to have been conserved throughout the course of evolution.
