Here we describe three complex class 1 integrons harboring the novel allele qnrB10 in a unique region downstream of orf513, one of them also containing aac(6')-Ib-cr within the variable region of integrons. The three arrays differed from bla(CTX-M-2)-bearing integrons, which are broadly distributed in Argentina.Antimicrobial agents and chemotherapy4466-70https://www.ebi.ac.uk/biostudies/studies/S-EPMC2167984biostudies-literatureComplex class 1 integrons with diverse variable regions, including aac(6')-Ib-cr, and a novel allele, qnrB10, associated with ISCR1 in clinical enterobacterial isolates from Argentina.PMC2167984Quiroga MPSoler Bistue AJGuerriero LTokumoto MGalas MCentron DVargas LJTolmasky MEPetroni AQuiroga CAndres PZorreguieta AfalseComplex class 1 integrons with diverse variable regions, including aac(6')-Ib-cr, and a novel allele, qnrB10, associated with ISCR1 in clinical enterobacterial isolates from Argentina.Transferable quinolone resistance has not previously been reported in Argentina.
