چکیده
Although onchocerciasis in cattle and horses in Japan had been noted in the veterinary field since the early 1950s, research on human onchocerciasis that is caused by Onchocerca volvulus was carried out only in the early 70s. It began when I did a brief study of skin test for onchocerciasis cases in Guatemala, Central America, in collaboration with Dr. H. Figueroa [1] using a Dirofilaria antigen [2]. Dr. Figueroa was an admirer of Dr. R. Robles, who discovered the presence and distribution of onchocerciasis on the American continents. Later on, many Japanese parasitologists participated in this field of research through the international health projects sponsored by Japan’s ODA (Overseas Development Assistance) agency (Overseas Technical Cooperation Agency (OTCA)/ and later Japan International cooperation Agency (JICA)) that were implemented in Ethiopia (after1969), Guatemala (after 1975) and Nigeria (after 1983).
