Phylogenetic lineages, clones and β-lactamases in an international collection of<i>Klebsiella oxytoca</i>isolates non-susceptible to expanded-spectrum cephalosporins

Abstract

The study confirmed the high genetic diversity of the collection of K. oxytoca ESC-non-susceptible isolates, composed of phylogroups with distinct types of OXY-type β-lactamases, and revealed some STs of broad geographical distribution.
