Dolosigranulum pigrum is a gram-positive, catalase-negative bacteria rarely associated with disease. We report a case of biomaterial-associated arthritis in an immunocompetent patient caused by D. pigrum. The organism was isolated from a synovial biopsy specimen and its identity confirmed by 16S rRNA gene sequencing.
