Hydrogen Peroxide Augments the Disinfection Efficacy of 280 nm Ultraviolet LEDs against Antibiotic-Resistant Uropathogenic Otherwise Tolerant to Germicidal Irradiation.

ABSTRACT: The 280 nm ultraviolet light-emitting diode (UV LED) has emerged as a promising water disinfection technology and has been applied from point-of-use devices to municipal-scale systems. Accumulating evidence suggests that small numbers of antimicrobial-resistant bacteria can survive UV treatment; however, little research has been done to evaluate 280 nm UV alone or as part of advanced oxidation processes against these organisms. Here, we investigated 280 nm UV LED inactivation of a high-risk uropathogenic () strain belonging to clade A of the globally distributed, antimicrobial-resistant ST131 lineage known to persist in treated wastewater (ST131-A). We measured disinfection efficacy with and without hydrogen peroxide (H₂O₂) and assessed the reactivation of the treated
