coli cell subpopulation with high levels of toxic reactive oxygen species (ROS, green), which induce the general stress response (red), and an intermediate state with both high ROS and stress ...

But when ROS dominates, it's like just cutting the weeds at the surface; the bacteria may look weaker at first ... More research needs to be done to fully understand the relation between RONS and ...

In this study, we showed that 310 nm UV-LED irradiation had weak bactericidal effects on oral bacteria but showed low toxicity to gingival epithelial cells. It also induced the production of ROS ...

Conversely, a ROS-dominant environment is akin to superficial cutting; the bacteria may initially appear ... which could lead to more effective antibacterial strategies in the future.” ...
