Abstract


Chronic intoxication associated with the ingestion of Senecio brasiliensis with concomitant interstitial and periductal pancreatitis induced by Eurytrema spp are described in a cow that demonstrated severe progressive emaciation as its principal clinical manifestation. In chronic seneciosis there was severe toxic hepatitis characterized by periportal and bridging fibrosis, megalocytosis, and proliferation of epithelial bile duct cells. Infestation by Eurytrema spp produced marked periductal and interstitial fibrosis associated with parasitic forms within interlobular pancreatic ducts.
