The MAB_3508c gene was shown to play a role in mediating these phenotypic changes, as its expression in\n            <jats:named-content xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" content-type=\"genus-species\" xlink:type=\"simple\">M. abscessus<\/jats:named-content>\n            cells was increased when they were treated with a subinhibitory dose of amikacin.
