Scientists discover small RNA that regulates bacterial infection

The Pharma Data

Scientists discover small RNA that regulates bacterial infection People with weakened immune systems are at constant risk of infection. But the bacteria can sometimes change their behavior and enter the bloodstream, causing chronic localized infections to become acute and potentially fatal. aeruginosa infections.
