A bumblefoot outbreak with different prognosis according to host species was studied in captive aquatic avian species. Six wood ducks (Aix sponsa), three scarlet-ibis (Eudocimus ruber), two black-swans (Cygnus atratus), five white-faced ducks (Dendrocygna viduata) and two roseate spoonbills (Platalea ajaja) were kept in a common pen with abrasive pavement pond margin, predisposing to podal skin wear. Incoordination and mortality occurred in the two roseate spoonbils and one black swan. Coagulase-positive penicillin-resistant Staphylococcus aureus was isolated from the synovial fluid and from the liver. All birds sharing the pen presented active or cicatricial foot lesions, indicating a possible challenge to the environmental Staphylococci. However, except for the roseate spoonbill and the black swan, which had fatal disease, for all other species the case did not evolve to a clinically debilitating or fatal disease. The different susceptibility to a fatal Staphylococcus aureus coagulase positive infection is discussed.
