Atypical myopathy is a pasture associated muscle disease with potentially devastating effects.
Other names include seasonal pasture myopathy (USA), pasture-associated myopathy and atypical myoglobinuria. Atypical myopathy is a severe muscle disease that occurs in pastured horses in the autumn or spring, and is not associated with exercise. This is in comparison to other muscle diseases that do present with clinical signs after exercise, such as exertional rhabdomyolysis (also known as “azoturia” or “Monday morning disease”) or polysaccharide storage myopathy (PSSM).
In the July edition Vikki H. L. Scott BVetMed, MSc, Dipl ACVIM, MRCVS discusses the updates on this potentially fatal disease.
