The ability to produce siderophore is considered to be a virulence factor for many pathogenic bacteria. To determine if siderophore production by coagulase-negative staphylococci (CNS) was related to virulence, 40 clinical isolates of CNS cultured from peritoneal dialysis fluid were compared with 38 commensal skin isolates. Siderophore activity was detected using the chrome azurol S liquid assay. Using precursor studies, Staphylococcus epidermidis isolates were shown to be more likely to produce the siderophore staphyloferrin A. Production of staphyloferrin B amongst non-Staphylococcus epidermidis species was associated with clinical isolates rather than commensal isolates, and therefore may play a role in pathogenicity.
Nasal commensals reduce Staphylococcus aureus proliferation by restricting siderophore availability.
