Abstract

The characterization of integrons and their promoters in 156 antibiotic-resistant clinical isolates of the important zoonotic pathogens subsp. serovars Typhimurium ( Typhimurium) and Enteritidis ( Enteritidis) from Norwegian hospitals were performed. Integrons were found in 64 of 66 isolates (97 %) and in 20 of 90 isolates (22.2 %) with the following sizes; 650, 1000, 1200, 1500, 1600, 1700, 2000 and 2100 bp. The integrons were further sequenced and the , , , , -, c, , , and genes, as well as a fragment of the gene, were found embedded in cassettes. An internal fragment of the gene was additionally found as an artefact PCR amplicon.
