Escherichia coli growing under antimicrobial gallium nitrate stress reveals new processes of tolerance and toxicity.

ABSTRACT: Metals have been used throughout history to manage disease. With the rising incidence of antibiotic-resistant bacterial strains, metal-based antimicrobials (MBAs) have re-emerged as an alternative to combat infections. Gallium nitrate has shown promising efficacy against several pathogens. Although its main toxicity mechanisms have focused on oxidative stress and its "trojan horse" iron mimetic strategy, there are still many knowledge gaps in the full-systems response elicited to counteract its toxic effects, especially in non-acute toxicity models that evaluate longer exposure times. In this study, we explore the transcriptomic response profile of Escherichia coli K12 BW25113 when challenged to grow planktonically for 10 h in the presence of a sublethal inhibitory concentration of gallium
