Oligella urethralis and Trueperella bernardiae are rare causes of bacteremia. A 96-year-old female nursing home resident with diabetes presented with polymicrobial bloodstream infection comprising these organisms and obstructive urinary tract infection. O. urethralis identified from blood cultures was resistant to fluoroquinolones and non-fourth-generation cephalosporins. Cases must be accumulated to define the clinical features of these organisms for infection control.

Oligella is a commensal bacteria genus of the human urinary tract that rarely precipitates clinical infections. We report the case of an asymptomatic 24-year-old male with a medical history of Tourette syndrome and the recent placement of deep brain stimulator leads, which were found to be co-infected with Oligella species during hardware implantation. This is the first reported case of a deep brain stimulator infection by Oligella, a potentially under-recognized and emerging opportunistic bacteria. We review the previously published cases of extra-genitourinary Oligella infections and detail the clinical management of this uncommon pathogen.
