The involvement of non-genetic factors in the emergence and development of diseases has been overlooked compared to genetic mutations. It is now believed that the assessment of non-genetic changes holds great potential for diagnosis, prevention, and treatment strategies for a wide range of diseases. Bacterial infections efficiently alter the hosts epigenome and play an important role in evading host immune responses, leading to bacterial infections and, in some cases, long-term persistence, as is the case with mycobacterial infections. To this end, we seek to understand the role of non-genetic mechanisms in promoting antimicrobial drug resistance (AMR) and pathogenesis. We believe that targeting the players responsible for these non-genetic mechanisms, in combination with the already existing battery of drugs, holds great potential to combat AMR and pathogenesis.
