Abstract
A kind of disease manifesting the chief symptom of motor paralysis of the extremities was found among chickens. The disease occurred especially in spring and summer. Relapses can often occur. Symptomatically and pathologic-histologically, the disease is similar to experimental athiaminosis. Moreover, Bacillus aneurinolyticus Kimura et Aoyama was found in the feces and in the intestinal tract, including the duodenum of the chickens. The bacillus must therefore be considered to be the cause of the disease.
The disease with slight symptoms can be cured spontaneously. Subcutaneous injection of thiamine or oral administration of streptomycin is effective for curing the disease.
