Abstract excerpt
Transferable quinolone resistance has not previously been reported in Argentina. 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.
