Muscular dystrophy in the duck.
Clinical and gross anatomy features of myopathic ducks are reported. Light microscopic examination of the leg muscles showed necrosis, degeneration and inflammation, and some degree of regeneration was also observed. There was infiltration and replacement of muscle fibres with fibrous tissue. Electron microscopy showed the early stages of myofilament dissolution and accumulation of glycogen in the presynaptic terminal of the neuromuscular junction.
