Outbreak of Serratia marcescens in a neonatal intensive care unit: contaminated unmedicated liquid soap and risk factors.

摘要: This study describes an outbreak of Serratia marcescens and its investigation control in a neonatal intensive care unit (NICU). During three-month period, five infants were colonised or infected by single strain S. marcescens. A case-control study, culture surveys pulse-field gel electrophoresis analysis implicated bottle soap dispenser as reservoir (P=0.032). Infants with colonisation infection also more likely to have been exposed central percutaneous venous catheter (P=0.05) had longer exposure endotracheal intubation (P=0.05). Soap dispensers are used many hospitals may be unrecognised source nosocomial infections. potential could reduced using 'airless' which no air intake for the distribution soap. Prompt intervention strict adherence alcoholic hand disinfection key factors that led successful this outbreak.
