Outbreak ofSerratia marcescensInfection in a Neonatal Intensive Care Unit

Abstract
We report an outbreak ofSerratia marcescensinfection in the neonatal intensive care unit of a community hospital. The outbreak involved eight neonates, (five infected and three colonized), one of whom died. Pulsed-field gel electrophoresis confirmed that all isolates were identical strains. Cohorting and isolation of the infected neonates helped to control the outbreak. No environmental source of infection was found.
