A 2-year-old female ostrich had become gradually emaciated over a 4-mo
nth period and subsequently died. Gross necropsy revealed a granulomat
ous mass ailing the right nasal passageways. Microscopically, the mass
contained numerous thin, regular-diameter, septate, branching fungal
hyphae consistent with Aspergillus sp. and foreign plant material. Thi
s appears to be the first report of a mycotic granuloma limited to the
nasal cavities of an ostrich or any other ratite species.
