Staphylococcus Lugdunensis Prosthetic Joint Infection

Staphylococcus Lugdunensis Prosthetic Joint Infection: a Retrospective Cohort Study

Staphylococcus lugdunensis is a coagulase-negative staphylococcus belonging to the human commensal cutaneous flora, and has been little studied in the field of prosthetic joint infections. However, it shares many virulence traits with Staphylococcus aureus, including many adhesins and its ability to form biofilm, and the few series of cases reports a significant failure rate.

Inclusion Criteria:

• infection of joint prosthesis (whatever its type) with Staphylococcus lugdunensis defined by the positivity of at least 2 gold-standard samples (joint puncture, intraoperative samples) with S. lugdunensis; OR
• a single positive gold-standard sample or positive blood cultures AND formal clinical, radiological, biological and / or pathological arguments in favor of an infection of joint prosthesis AND absence of other pathogenic agent

Exclusion Criteria:

• none
