Necrotizing meningoencephalitis in a calf

Abstract

A 6-month-old male Red Angus calf from São Vicente do Sul, Rio Grande do Sul (Brazil) died after an 8-day history of anorexia, dullness, blindness, aimless walking, and circling. The calf was part of a herd of 300 calves that had been weaned and placed on an oat pasture 20 days before the onset of clinical signs. Two additional calves had similar clinical signs and died during the same period.
