Clonal spread and intra- and inter-species plasmid dissemination associated with KPC-producing Enterobacterales during a hospital outbreak in Barcelona, Spain

We report the clonal dissemination of a ST15 K. pneumoniae as well as the intra- and inter-species plasmid dissemination associated with blaKPC-2-producing Enterobacterales during a hospital outbreak in a tertiary hospital. Although implementation of infection control measures led to the full control of the outbreak situation in just a few months, surveillance programs should be reinforced.
