Pediatric bacteremia due to Staphylococcus warneri: microbiological, epidemiological, and clinical features

Abstract

Between 1991 and 1995, an apparent high rate of Staphylococcus warneri bacteremias at the Royal Children's Hospital, Melbourne, Victoria, Australia, raised the possibility of a virulent nosocomial strain. In a retrospective review of 30 S. warneri bacteremias in children, organisms were viable and verified in 22 episodes, 12 representing significant bacteremias. Of these 12 episodes, 2 pairs shared chromosomal DNA pulsed-field gel electrophoresis patterns in unconnected patients, dispelling concerns about a single virulent strain.
