Abstract
A kind of disease with the main symptom of motor paralysis of extremities was found among chickens. The disease happens chiefly in the spring and summer. The recidivation can often be seen. Symptomatically and pathologic-histologically the disease is similar to the experimental B-avitaminosis. Moreover Bacillus aneurinolyticns Kimura et Aoyama was found in the feces and intestinal tracts including duodenum of the chickens. Therefore the bacillus must be considered as a cause of the disease. The disease of slight symptoms can be got well spontaneously. Subcutaneous injection of thiamine or peroral administration of streptomycin is effective for the disease.
