The present study aimed to report the occurrence as well as the clinical, laboratorial, pathological and mycological findings of three outbreaks of rhinocerebral and rhinopharyngeal conidiobolomycosis in sheep from Rio Grande do Norte state, Brazil. A total of six sheep with clinical signs of conidiobolomycosis were evaluated, and information on history was obtained from ranchers. Clinical signs included depression, progressive emaciation, sero-sanguinolent nasal discharge, tachycardia, dyspnea, miosis and unilateral exophthalmia with increased ocular globe volume, corneal ulceration and nervous system signs. The main hematological alteration was neutrophilia. Serum biochemical evaluation revealed increased values for AST, GGT, creatinine, urea, and glucose, and decreased total proteins and albumin levels. Cerebrospinal fluid analysis showed the presence of fibrin reticules and pleocytosis. Upon necropsy, longitudinal sections of the head revealed the presence of a nodular mass with a friable consistency and a white-yellowish coloration. Microscopic findings included meningitis, cortex necrosis and encephalitis with the presence of eosinophilic Splendore-Hoeppli substance. Histopathology of the lungs revealed a Splendore-Hoeppli-like material and hyperplasia of alveolar and bronchiolar epithelium. Renal lesions were suggestive of amyloidosis.O presente estudo objetivou relatar a ocorrência e os achados clínicos, laboratoriais, patológicos e micológicos de três surtos de conidiobolomicose rinocerebral e rinofaríngea em ovinos do estado do Rio Grande do Norte, Brasil. Um total de seis ovinos com sinais clínicos de conidiobolomicose foi avaliado, e informações sobre o histórico foram obtidas dos proprietários. Os sinais clínicos incluíram depressão, emaciação progressiva, descarga nasal serossanguinolenta, taquicardia, dispneia, miosite e exoftalmia unilateral com aumento do volume do globo ocular, ulceração da córnea e sinais nervosos. A principal alteração hematológica foi neutrofilia. A avaliação bioquímica sérica revelou aumento nos valores de AST, GGT, creatinina, ureia e glicose, e redução nos níveis de proteínas totais e albumina. A análise do fluido cerebrospinal revelou presença de retículos de fibrina e pleocitose. À necropsia, secções longitudinais da cabeça revelaram presença de uma massa nodular com consistência friável e coloração branco-amarelada. Os achados microscópicos incluíram meningite, necrose do córtex e encefalite com presença da substância eosinofílica de Splendore-Hoeppli. A histopatologia dos pulmões revelou uma substância similar à de Splendore-Hoeppli e hiperplasia do epitélio alveolar e bronquiolar. As lesões renais foram sugestivas de amiloidose.
