Genetic Environment of Quinolone Resistance Gene <i>qnrB2</i> in a Complex <i>sul1</i> -Type Integron in the Newly Described <i>Salmonella enterica</i> Serovar Keurmassar

Abstract

A qnrB2 determinant was described for a new complex sul1-type integron from Salmonella enterica serovar Keurmassar. The genetic structure contained two class 1 integrons surrounding two common regions (CRs) separated by a partial 3' conserved segment. The qnrB2 gene is adjacent to the first CR.
