Japanese quail inoculated subcutaneously with Borrelia garinii responded to infection. B. garinii was reisolated mainly from skin and randomly from several organs between 7 and 56 days postinoculation. Skin lesions were occasionally observed in association with spirochete recovery. All birds were positive for antibody at 53 to 56 days postinoculation. These(More)
Fibromuscular dysplasia (FMD) was found in the intramuscular arteries of both commercial (normal) and mutant (LWC) strains of Japanese quail. The mutant strain LWC is afflicted with an inherited muscular dystrophy exhibiting myotonia. The arterial lesions were classified as medial fibroplasia or medial hyperplasia, both being subtypes of medial FMD. Some(More)
Five German shepherd puppies, aged between 66 and 174 days (4 of which had the same parents) had ananastasia with deformation of limbs. Histopathologically, all the puppies showed moderate to marked fibrous osteodystrophy with parathyroid gland activation. These puppies were fed a diet consisting of 80% steamed rice and 20% raw meat. It was implied that(More)
The progression of the pathological changes that occur in the skeletal muscle was examined in 19 Japanese quail of the LWC strain, affected with an autosomal dominant inherited muscular disorder producing electrical myotonia. The muscle samples were obtained every 10 days from 20 to 70 days of age. Muscle samples from 18 age-matched commercial quail were(More)
Ultrastructural study of muscles taken from a mutant (LWC) strain of Japanese quail with myotonia showed type 2 fibre atrophy, ring fibre formation, sarcoplasmic masses, and "moth-eaten" fibres. In these abnormal fibres, the most characteristic feature was the loss of interconnection among the myofibrils, mitochondria, and T tubules. Apparently normal(More)
Between January and April, 1992, two captive Bennett's wallabies (Macropus rufogriseus) from a wildlife park in Iwamizawa City, Hokkaido, Japan, were diagnosed as having nutritional myopathy. One wallaby, four-year-old adult male, had mild fresh lesions, confined to the skeletal muscles, with poor cell reaction. The other wallaby, 8-month-old female joey,(More)
Thirteen adult mutant (LWC strain) Japanese quails (Coturnix coturnix japonica), between the ages of 8 and 60 weeks were examined for a progressive muscular disorder. The disorder, inherited as an autosomal dominant trait, was clinically apparent as early as 28 days of age; it was characterized by generalized myotonia, muscle stiffness, and muscle weakness.(More)

Cryostat sections of myofibres from the Musculus pectoralis thoracicus of a newly established mutant strain (LWC) of Japanese quail with a myotonic dystrophy-like myopathy were labelled with antibody against myosin heavy chain (MHC) isoforms and neural cell adhesion molecule (N-CAM). The characteristic lesions found in sections of muscle of LWC quail(More)
