The muscle biopsy showed mild type 2 fibre atrophy, type 1 fibre preponderance, variability in fibre size, and changes in the myofibrillar pattern of affected fibres. Interfascicular macrophages contained PAS-positive material. With the electron microscope these macrophages contained membranous inclusions and bacillary bodies, similar to those seen in the jejunal biopsy.
