Abstract

Epizootics and sporadic outbreaks of the cattle disease characterized by fever, stomatitis and dysphagia were observed in Korea in September through November, 1982. The number of cattle showed typical symptoms of the disease was estimated to 73 and these animals were concentrated in Gyongido province, the central district of Korea. In other districts around Gyongido province the disease tended to be sporadic occurrence. The main lesions of the disease were defined as edema, hemorrhage, degeneration and necrosis of the oral mucosa and musculatures of the esophagus and laryngopharyngeal area, and abomasum. Of these lesions hyaline degeneration and hemorrhage of the striated muscle of the esophagus and laryngopharyngeal area were the most striking changes of the disease and rated to be the lesion of diagnostic significance. The serum samples of the cattle with typical symptoms showed significant positive titer of the antibodies against Ibaraki virus. On these clinical, epidemiological, pathological and serological findings of the disease it was diagnosed as Ibaraki disease presenting the only report on the epizootics in the countries other than Japan.
