Prevotella bivia is gram-negative anaerobic bacteria previously classified in the genus Bacteroides and usually reported in obstetric and gynecologic infections. To our knowledge, there has been only 2 descriptions of infectious arthritis secondary to this bacterium. We report the first case of a spontaneous prosthetic septic arthritis caused by Prevotella bivia in a patient with long-lasting polymyalgia rheumatica.
