Staphylococcus lugdunensis


Routine Practices


General Information

  • Gram positive cocci in clusters
  • Coagulase negative
  • Often oxacillin susceptible
  • Often pathogenic

Skin flora

  •  Endocarditis

  •  Osteomyelitis

  •  Blood stream infections

  •  Prosthetic joint infections

  •  Skin and soft tissue infections

Coagulase negative but clinically behaves more like Staphylococcus aureus and is more virulent than other coagulase-negative Staphylococci.

Staphylococcus lugdunensis should be treated as a true pathogen in most scenarios.

Different from most coagulase negative Staphylococci as most CoNS are methicillin resistant and S. lugdunensis is generally beta-lactam susceptible.
