S. lugdunensis Native-Joint Septic Arthritis: Case Report and Review of the Literature

Abstract

Staphylococcus lugdunensis is a skin commensal classified as a coagulase-negative Staphylococcus (CoNS). Though CoNS is typically associated with less aggressive clinical disease than Staphylococcus aureus , there is growing awareness that S. lugdunensis may be as virulent as S. aureus . The association between S. lugdunensis and infective endocarditis is well known, but few reports of native-joint disease with this organism exist. We report a case a 28-year-old male with no prior medical problems presenting with native-joint septic arthritis. Cultures grew S. lugdunensis . To our knowledge, this is the fifth case reported in the literature.
