High-resolution imaging reveals the secrets of a bacterial toxin

14-Jul-2016

Many bacteria use specialized toxins to attack and infect other cells. Scientists at EPFL and the University of Bern have now modeled a major such toxin with unprecedented resolution, uncovering the way it works step-by-step. In order to infect other cells, many bacteria secrete a type of toxin ...
