High temperatures increase the virulence of Vibrio bacteria towards their coral host and competing bacteria via typeAU VI secretion: Pleasenotethat}type6 systems

Abstract

The bacterial pathogen Vibrio coralliilyticus induces severe coral diseases in warming oceans. A study in PLOS Biology reveals that high temperatures activate 2 type VI secretion systems in V. coralliilyticus, enhancing pathogenicity by deploying toxic effectors against competing bacteria and coral cells.
