NewsResearchers discover molecular ‘barcode’ used by bacteria to secrete toxins
Researchers have discovered a molecular “barcode” system used by disease-causing bacteria to distinguish between beneficial and toxic molecules.
-
NewsResearchers unmask an old foe’s tricks to thwart new diseases
Researchers are studying Yersinia pestis, the bacterium that causes bubonic and pneumonic plague, to better understand its ability to evade the immune system and apply that understanding to control other pathogens.
