Successful Eradication of a Monoclonal Strain of Klebsiella pneumoniae during a K. pneumoniae Carbapenemase-Producing K. pneumoniae Outbreak in a Surgical Intensive Care Unit in Miami, Florida

We describe the investigation and control of a Klebsiella pneumoniae carbapenemase-producing K. pneumoniae outbreak in a 20-bed surgical intensive care unit during the period from January 1, 2009 through January 1, 2010. Nine patients were either colonized or infected with a monoclonal strain of K. pneumoniae. The implementation of a bundle of interventions on July 2009 successfully controlled the further horizontal spread of this organism.
