Variability in the region downstream of the blaCMY-2 beta-lactamase gene in Escherichia coli and Salmonella enterica plasmids.
We used sequencing and PCR mapping to investigate the regions flanking the blaCMY-2 beta-lactamase gene carried by plasmids from Escherichia coli and Salmonella enterica. Results revealed genetic heterogeneity in the region downstream from blaCMY-2 and identified a putative transposable element bearing blaCMY-2.
