Rapidly controlled outbreak of Serratia marcescens infection/colonisations in a neonatal intensive care unit, Pescara General Hospital, Pescara, Italy, April 2011.

In April 2011, an outbreak of Serratia marcescens infection/colonisations occurred in the neonatal intensive care unit of Pescara General Hospital. Rapid microbiological investigations lead to identification of five cases of likely cross-transmission from a neonate hospitalised for S. marcescens sepsis: four infections and one neonate colonised post-mortem. Two low birth weight neonates died. The environmental investigation detected S. marcescens from two soap dispensers. Strict hygiene measures lead to early interruption of the outbreak, without recurrences to date.
