A Captive mute swan with swelling abscesses in foot pads of both legs was presented. A complete blood count reveals systemic infection. Radiographs showed radiopaque areas in foot pad of both legs and osteomyelitic periosteal reaction in left foot. After anesthesia, surgical debridement was carried out to remove pus and necrotic tissue on the plantar surface of both feet. Full surgical debridement, effective antibiotics, good post-surgical care and husbandry are affecting factors that cause no recurs of disease despite osteomyelitis.
