A 10-year-old Aberdeen Angus cow was presented to the Large Animal Medicine Service at Federal University of Santa Maria Veterinary Hospital with a history of weight loss for the past 6 months, watery diarrhea for the last 30 days, tenesmus, and fever. The owner reported the presence of the plant Senecio brasiliensis on pasture and that 10 cattle had died on his property during the past 4 years demonstrating similar antemortem clinical signs as the cow that was presented. On physical examination, the cow was dehydrated and mildly febrile (101.7°F) with pale mucous membranes. A moderate mature neutrophilia was noted on the CBC (17,300 cells/lL, RI 4000– 12,000). The biochemical serum panel revealed mild hypoalbuminemia (2.79 g/dL, RI 3.30–3.55), moderately decreased AST activity (36 IU/L, RI 78–132), markedly increased GGT activity (39.98 IU/L, RI 6.10–17.40), and moderately decreased urea concentration (35.33 mg/dL, RI 42.80–64.20). A fine-needle aspirate (FNA) smear of the liver was submitted for cytologic evaluation (Figure 1), and a liver biopsy was collected and routinely processed for histopathology. Figure 1.
