The epidemiological, clinical, pathological and mycological findings of an outbreak of conidiobolomycosis in a flock of 40 Santa Ines sheep, in the state of Mato Grosso, Brazil, are reported. The illness occurred in the municipality of Nobres during January-June, 2007, resulting in death of about 30% of the affected sheep within 2-5 weeks. The clinical signs were characterized by apathy, weight loss, labored and noisy breathing with dyspnea, and mucous or serohemorrhagic nasal discharge. In three sheep there was unilateral exophthalmia, keratitis and corneal ulceration. A firm whitish, multi-lobulated, friable growth was evident in the ethmoturbinate region at the coronal sections of the head from six affected sheep. In all sheep the choana had similar nodular infiltration which resulted in local obstruction. In three of those there was exophthalmia. There was infiltration in the cribiform plate and brain (2 cases), regional lymph nodes (2), lungs (3), and abomasums (1). Microscopic findings were granulomatous inflammation of the rhinoetimoidal region, with necrosis, lymphocytic infiltration, epithelioid multinucleated giant cells and fibrovascular tissue, surrounding Splendore-Hoeppli material wich contained unstained ghost images of hyphae. The methenamine-silver stain uncover fungi hyphae, rarely ramified with bulbous dilatation in their extremities. Conidiobolus sp. was isolated from nasal tissue lesions of four sheep.
