Sequence Analysis of pKF3-70 in Klebsiella pneumoniae: Probable Origin from R100-Like Plasmid of Escherichia coli

Abstract

The K. pneumoniae plasmid pKF3-70 carries an extended-spectrum beta-lactamase gene, ctx-m-14. The conjugative characteristic makes it a widespread plasmid among genetically relevant genera which poses significant threat to public health.
