Abstract:

With the rapid development of antimicrobial resistance(AMR)and the increasing emergence of new antimicrobial-resistant bacteria, there are fewer and fewer antibiotics available for therapeutic options. Controlling the dissemination of resistance genes, without directly killing pathogens, is becoming a novel strategy to combat AMR. Plasmid acts as one of the most important vectors of resistance genes. It can be disseminated globally to bacterias of diverse sources(e.g., animal, human being, foods, and environment)through conjugation, and plays an important role in the transmission of AMR. Thus, inhibiting the conjugative transfer of plasmids is considered as a promising approach to control AMR and has been attracting more and more attentions of the researchers. This review briefly introduced the mechanism of AMR transfer, expounded the process and mechanism of plasmid conjugation, and summarized the progress of conjugation inhibitors,aiming to provide reference for the development of new strategies to control AMR.

Key words: resistance, plasmid, conjugation, conjugation inhibitor
