Molecular Epidemiology of <i>Serratia marcescens</i> Outbreaks in Two Neonatal Intensive Care Units

Abstract

S. marcescens causes significant morbidity and mortality in preterm neonates. Cross-transmission via transient hand carriage of a HCW appeared to be the probable route of transmission in NICU A. Sinks did not harbor the outbreak strains. Antimicrobial susceptibility patterns did not prove to be an accurate predictor of strain relatedness for S. marcescens.
