A granulomatous conjunctivitis associated with Morexella phenylpyruvica in an ostrich (Struthio camelus).

The aim of study was to evaluate a case of granulomatous conjunctivitis, clinically and pathologically, in the right eye of a 2-year-old, female ostrich. A mass measuring 5 cm x 3 cm x 4 cm was removed surgically from the eye of the ostrich. Morexella phenylpyruvica was recovered from the mass. On histopathological examination, hyperplasia or squamous metaplasia in some area of conjunctival palpebra, and a granulomatous inflammation in the submucosa were observed. The lesion was described as a granulomatous conjunctivitis caused by M. phenylpyruvica. The lesion was located in the lower eyelid conjunctiva and was not only restricted to the gl. lacrimalis, but also present in the connective tissue. After excision of the mass, the ostrich was treated with topical and systemic antibiotics and corticosteroid. The ostrich recovered fully and the function of the eye appeared to be normal.
