Association of IS26-composite transposons and complex In4-type integrons generates novel multidrug resistance loci in Salmonella genomic island 1

Abstract

The serovar Haifa represents the 16th S. enterica serovar in which SGI1 has been identified. The genomic island SGI1 appears to be a hotspot of acquisition of antibiotic resistance genes by the transposition of In4-type integrons and large IS26-composite transposons.
