Eikenella corrodens-caused botryomycosis-type pneumonia in a barbary ape (Macaca sylvanus)

An 18-year-old female barbary ape in a safari park died from a mixed bacterial infection. Staphylococus aureus was isolated from a purulent necrotic mastitis and from a chronic purulent granulomatous sialoadenitis of the sublingual glands, Eikenella corrodens from a botryomycosis-type pneumonia. As judged by histopathology, mixed infection of S. aureus and E. corrodens was present in the sialoadenitis, and E. corrodens botryomycosis-type bacterial colonies were also present in the pancreatic parenchyma, though here no bacteriological isolation was attempted. A generalized amyloidosis, and especially pancreatic islet amyloidosis, probably indicated an altered immunological competence.
