Abstract:
Serratia marcescens strains commonly cause hospital outbreaks. A random amplified polymorphic DNA (RAPD) assay was applied to the epidemiology of Ser. marcescens using formaldehyde fixation and boiling of bacterial cells for DNA extraction. The method preserved bacterial DNA and gave optimal results of RAPD-fingerprinting, facilitating the investigation of hospital infections caused by Ser. marcescens.
