Beyond Genes: Non-Canonical Mechanisms Driving Antimicrobial Resistance In Bacteria, Leonard Koolman, Chijioke Emenike, Debasis Mitra, Sourav Chattaraj

Research Outputs: 2025-Present

Antimicrobial resistance (AMR) is traditionally discussed in the context of horizontally acquired resistance genes and point mutations at target loci. However, this gene-centred model fails to account for a large number of clinically important modalities of resistance. There is now substantial evidence implicating bacteria in the ability to escape the effects of antibiotics in a variety of non-canonical ways, which are not considered in traditional diagnostic and surveillance pipelines. Among these factors, we can list those arising from global regulatory networks, phase variability, epigenetic tuning, small RNAs, genome structural variability, and phenotypic states like tolerance and persistence. This review will …
