Novel genetic manipulation tools are required to elucidate the biology, pathogenesis, and antibiotic resistance mechanisms of\n                    <jats:italic>M. abscessus<\/jats:italic>\n                    . In this study, we modified the method used to prepare\n                    <jats:italic>M. abscessus<\/jats:italic>\n                    electrocompetent cells to achieve efficient transformation, and then optimized the CRISPR\u2010Cas9\u2010assisted genome\u2010editing tools to allow efficient genetic manipulation. Using these tools, we constructed 66 efflux pump mutants of\n                    <jats:italic>M. abscessus<\/jats:italic>\n                    and investigated their roles in drug resistance and virulence. We found that different efflux pumps play distinct roles in drug resistance and survival in\n                    <jats:italic>Galleria mellonella<\/jats:italic>\n                    larvae. Finally, we confirmed that MAB_2806\u20102807, involved in transportation of triacylglycerides, is vital for the drug resistance and virulence of\n                    <jats:italic>M. abscessus<\/jats:italic>\n                    .

In addition, the study on efflux pumps might provide new targets for the development of new drugs and treatment regimens for\n                    <jats:italic>M. abscessus<\/jats:italic>\n
