Detection of Virulence-Associated Genes Not Useful for Discriminating between Invasive and Commensal <i>Staphylococcus epidermidis</i> Strains from a Bone Marrow Transplant Unit

Abstract excerpt

Because of their biofilm-forming capacity, invasive Staphylococcus epidermidis isolates, which cause the majority of nosocomial catheter-related bloodstream infections (BSIs), are thought to be selected at the time of catheter insertion from a population of less virulent commensal strains. This fact allows the prediction that invasive and contaminating strains can be differentiated via detection of...
