We’ve discovered how the superbug E. faecalis prevents chronic wounds from healing. It’s not a toxin. It’s metabolism. The bacteria use extracellular electron transport (EET) to electrochemically generate ROS, effectively "freezing" skin cells in place. doi.org/10.1126/sciadv.aeb5297

Enterococcus faecalis redox metabolism activates the unfolded protein response to impair wound healingE. faecalis EET generates ROS, which induces the UPR in keratinocytes, inhibiting in vitro migration.doi.org
