Abstract
After the euphoria of the antibiotic discovery and their tremendous action on bacterial infections outcomes, arrives a period of fear with the continuous emergence of bacteria that are resistant to almost all antibiotic treatments. It is becoming essential to better understand antibiotic resistance mechanisms to find new approaches to prevent the worldwide problem of multiresistance. The role of antibiotics on the direct induction of resistance acquisition is known. Recent studies have shown that some antibiotics, by inducing the bacterial SOS response, global repair response after DNA damages, are involved on a broader level in the induction, acquisition and dissemination of resistances in bacteria. We discuss here the role of antibiotics in resistance acquisition via the SOS response through several examples and the interest of identifying the SOS response regulators as the future targets of new families of antimicrobial molecules.
