Abstract

Photosensitization occurs in everyplace domestic animals are farmed along the world. Several studies are uncertain about Pithomyces chartarum involvement and its relationships with Brachiaria decumbens pasture in liver disease. This article describes clinical and pathological aspects observed at photosensitisation outbreak at Cuiabá, Mato Grosso, Brazil. Samples of liver, kidney, spleen and lymph nodes were collected after eleven sheep deaths and had sent to microscopic examination. Gall bladder epithelial cells proliferation, presence or absence of bile stasis, hepatic degeneration, cellular necrosis focus and multinucleated cell’s focus were found. The results appoints to closed relationship between hepatic and renal lesions and Brachiaria decumbens ingestion by sheep’s.

KEY WORDS: Brachiaria spp, hepatic lesions, ovine.
