Identification of Proteus genomic island 2 variants in two clonal Proteus mirabilis isolates with coexistence of a novel genomic resistance island PmGRI1

Abstract

The finding of the two new PGI2 variants highlights that the homologous recombination between shared components of class 1 integrons and transposition by IS26 promote the diversity of MDR regions in PGI2. PmGRI1 is a new GI that carries various resistance genes identified in P. mirabilis and E. coli.
