General Information

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.
