Complex molecular epidemiology of extended-spectrum -lactamases in Klebsiella pneumoniae: a long-term perspective from a single institution in Madrid

Abstract

K. pneumoniae is still an important ESBL producer in our institution with a complex epidemiology. The main features were a few outbreaks with persistence of specific plasmids, emergence of new enzymes and an increment in community isolates. These results should be taken into account for the implementation of epidemiological containment measures.
