Abstract:
Serratia marcescens is now recognized as a serious pathogen and of particular importance in nosocomial infections. Both hand-to-hand and point-source transmission can result in outbreaks. The organism is easily grown and identified in the microbiology laboratory. Treatment may be difficult due to plasmid-mediated resistance. Typing systems are available and can be useful for epidemiologic studies.
