AbstractCoagulase-negative Staphylococcus warneri is a rare cause of human disease, which as a rule manifests as an insidious and protracted infection of various prostheses and endovascular catheters. A case of Staphylococcus warneri sepsis with multiple abscesses in an immunocompetent patient free from the usual predisposing factors for coagulase-negative staphylococcal infection is presented. To our knowledge, this is the first case of sepsis with multiple abscesess caused by this bacterium reported in the literature.
