In the present work, we, first, have observed the pathological changes due to all kinds of filaria collected from cattle, thereafter, we have investigated clinically, pathologically and etiologically the "Kose" disease in cattle. The results obtained are as follows : 1. Microfilariae of Setaria are found in circulating blood only, producing no lesions in the skin of cattle. 2. Microfilariae of Onchocerca gutturosa are found mostly in the dermal connective tissue and dermal blood vessels and partly in circulating blood, producing the remarkable inflammatory lesions in the skin of cattle. Microfilariae of both developmental stages mentioned in the previous report show the pathogenity alike. 3. Above mentioned lesions due to these microfilariae consist of the infiltration of eosinophil leucocytes and round cells and the production of connective tissue, and are commonly invisible macroscopically. 4. 90% of cattle in this country are attacked by such invisible lesions, being treated as the healthy animals. 5. However, the lesions are sometimes visible with the naked eyes as an elephantiasis-like disease on account of the serious illness, accompanying itching usually. Cattle attacked by such lesions are treated as the "Kose" diseased animals. 6. Although "Kose" disease is, in this way, caused by microfilaria of Onchocerca gutturosa, allergy must be required certainly for its pathogenesis.
