title: Actinobaculum schaalii, a new cause of knee prosthetic joint infection in elderly.
abstract: Actinobaculum schaalii is an emerging pathogen particularly involved in urinary tract infection of elderly people and/or patient with urological risk factors of urinary tract infection. This microorganism is a difficult-to-diagnose pathogen and is rarely involved in systemic or deep infections. Here, we report the first case of prosthetic joint infection due to A. schaalii in an 84-year-old man with a benign prostatic hyperplasia associated with chronic retention of urine. This case underlines the importance to optimize the diagnosis of emerging uropathogens as A. schaalii, to prevent systemic infections, particularly in patients with orthopaedic implants.
