RESUMO
Cases of seneciosis in horses occurring in four farms in the state of Santa Catarina and in another in the state of Rio Grande do Sul, southern Brazil, are reported. S. brasiliensis or S. oxyphyllus or both were detected in four of the five properties. Five horses (one on each property) were necropsied, and tissues for histopathological examination were collected from four horses. Neurological signs, such as depression, ataxia, aimeless walking, circling, head pressing, faulty prehension of food, dysphagia and blindness were consistently observed. Other signs included inappetence, loss of weight, colic, subcutaneous edema, icterus and photodermatitis. At necropsy the livers were firmer and darker than normal and had accentuation of lobular pattern. Edema of the mesentery and ascites were observed in one horse. Main histopathological changes consisted of hepatic chiefly periportal fibrosis, hepatomegalocytosis and biliary hyperplasia. Marked cholestasis and morphological evidence of hepatic encephalopathy were seen respectively in the liver and brain of one of the horses
