Abstract: An outbreak of zigomycosis with rhinopharyngeal lesions involving fungal hyphae with characteristic of entomophthoromycosis due to Conidiobolus spp. is reported in the State of Pernambuco, Northeastern Brazil. The epidemiological, clinical, pathological and mycological findings are decrypted in a flock of Santa Inês sheep. The disease occurred at Nazaré da Mata from April to May 2009, all most cases occurred mainly during the rainy season affecting 5 sheep of 29, resulting in death of about 100% of the affected sheep. Clinical signs as noisy respiration and dyspnoea due to mechanical blockage of the nasal cavities, swelling of the nostrils and mucous or serosanguineous nasal discharge were observed. Two of 5 sheep showed exophthalmia, keratitis and unilateral corneal ulceration of the eye. The sheep either died of their infection or were euthanized after a clinical course of 7-20 days. At necropsy there was a firm whitish, lobulated, friable growth was evident in the ethmoidal region and nasal septum at the sagital sections of the head from four affected sheep. Histopathologically findings were multifocal granulomas with lymphocytic infiltration, epithelioid multinucleated giant cells and fibrovascular tissue, surrounding an eosinophilic necrotic reaction (Splendore-Hoeppli phenomenon). The methenamine-silver stain uncovered fungal hyphae, rarely ramified with bulbous dilatation in their extremities. Conidiobolus sp. was isolated from nasal tissue lesions of two sheep. This is the first report of disease in the State.

Resumo: Os achados epidemiológicos, clínicos, patológicos e micológicos de um surto de zigomicose com lesões rinofaringeais envolvendo a presença de hifas fúngicas com características de enteroftoromicose por Conidiobolus spp, são descritos no Estado de Pernambuco. A doença ocorreu no Município de Nazaré da Mata entre abril e maio de 2009, durante o período chuvoso afetando 5 ovinos de um total de 29, resultando na morte de 100% dos ovinos afetados. Os sinais clínicos consistiram em respiração ruidosa, dispnéia por obstrução das cavidades nasais, deformação facial e exsudação nasal mucosa ou serosanguinolenta. Os ovinos morreram ou foram eutanasiados após um curso clínico que variou de 7-20 dias. Vistos á secção sagital da cabeça, os achados de necropsia consistiram na presença de um crescimento granulomatoso, firme e esbranquiçado na região dos etmóides e septo nasal dos ovinos afetados. Os achados histopatológicos consistiram na presença de granulomas com infiltração linfocítica, de células gigantes multinucleadas e de tecido fibrovascular, circundados pelo fenômeno de Splendore-Hoeppli. Hifas fúngicas pouco septadas, com dilatação bulbosa das extremidades foram identificadas pela coloração da prata-metamina. Conidiobolus sp. foi isolado do tecido nasal de dois ovinos. Este é o primeiro relato da doença no Estado.
