Clonal expansion and horizontal transmission of epidemic F2:A1:B1 plasmids involved in co-spread of<i>rmtB</i>with<i>qepA</i>and<i>bla</i>CTX-M-27 in extensively drug-resistant<i>Salmonella enterica</i>serovar Indiana isolates

Abstract

This is the first report, to our knowledge, of the prevalence and complete sequences of plasmids simultaneously containing rmtB, qepA and blaCTX-M-27. These findings underscore a major public health threat posed by epidemic F2:A1:B1 plasmids bearing qepA-rmtB-blaCTX-M-27 that are circulating in XDR Salmonella Indiana clonal isolates from waterfowl husbandry.
