Disseminated Infection Caused by Staphylococcus schleiferi: A Dangerous Wolf in Coagulase-Negative Staphylococcus Clothing

Staphylococcus schleiferi is a coagulase-negative staphylococcus known to cause canine external otitis but has rarely been reported in human infections. However, unlike other coagulase-negative staphylococci, S. schleiferi can cause disseminated infection in immunocompetent patients. Here, we present a case of S. schleiferi bacteremia, accompanied by infective endocarditis, brain abscesses, acute focal bacterial nephritis, and possible epididymitis, in which an S. aureus bacteremia treatment strategy was useful for resolution. Further reports should be accumulated to determine if S. schleiferi is a virulent pathogen that frequently causes the disseminated infection type seen in our patient.
