Aspergillus clavatus as the probable cause of a lethal mass neurotoxicosis in sheep.
Sprouted barley grains, the waste product of malt extract production, were incriminated as the cause of a lethal (96% mortality) neurotoxic syndrome in sheep fed the grains. Clinical manifestations, comprising tremors, lameness, abnormal gait, paralysis and death indicated a tremorgenic mycotoxicosis. Whilst 50% of the flock died within 17 days, mortality continued over more than 5 months. Pathological findings were limited to neuronal degeneration and necrosis in the midbrain. Germinating grains were shown to be contaminated with growth of Aspergillus clavatus.
