Summary
We report on nosocomial infections caused bySerratia marcescens occurring in a neonatal intensive care unit and a children's ward for cardiac intensive care. According to the plasmid pattern analysis, all isolated epidemic strains belonged to one clone. Multidrug resistance, even to cephalosporins of the third generation and amikacin, was characteristic for all strains. Certain markers ofS. marcescens (haemolysin, proteases, siderophores) which are thought to be related to virulence were studied but will require further investigation.
Zusammenfassung
Es wird über nosokomiale Infektionen durchSerratia marcescens auf einer neonatologischen Intensivtherapiestation und einer pädiatrisch-kardiologischen Überwachungsstation berichtet. Nach der Plasmidmusteranalyse gehören die isolierten Stämme einem Epidemieklon an. Charakteristisch für alleS. marcescens-Stämme ist eine Multiresistenz, auch gegen Cephalosporine der dritten Generation und Amikacin. Bestimmte Merkmale der Infektionserreger (Hämolysin, Protease, Siderophore), die mit der Virulenz in Zusammenhang gebracht werden, bedürfen weiterer Untersuchungen.
