Staphylococci, coagulase negative
Rule out contamination If true pathogen - vancomycin
Depends on MICs
Gram positive cocci in clusters, coagulase-negative
Skin flora; common contaminant/colonizer
MecA identification (BioFire) for CoNS is common. An MIC of 2 to vancomycin in CoNS is not a contraindication to its use.
Isolated identification or multiple morphtypes of CoNS may represent contamination.
Staphylococcus lugdenensis acts more like S. aureus and is more virulent than other CoNS - should always be considered a pathogen, ID consult recommended.
