Draft Genome Sequences of the Clinical Isolates Kp 23 and KPM 20

Klebsiella pneumoniae emerge resistant to beta-lactam antibiotics through production of beta-lactamase enzymes and alterations in outer membrane permeability. These draft genomes describe two clinical isolates of Klebsiella pneumoniae. One, Kp 23, contains no plasmid-encoded beta-lactamases and phenotypically expresses the outer membrane porins: OmpK35, OmpK36, and PhoE. The other, KPM 20, contains no plasmid-encoded beta-lactamases and phenotypically does not possess the outer membrane porins: OmpK35, OmpK36, and PhoE. These provide comparator strains for the analysis of membrane permeability in beta-lactam resistance.
