島根県下で続発した皮膚顎口虫症4例と感染源ドジョウの検索

Four cases of cutaneous gnathostomiasis successively occurred in 1989 were reported with references to the loaches as the source of infection. The patients complained of migratory cutaneous swellings of their faces or the creeping eruption of the body after they took raw loaches at the Japanese restaurant in Tamayu-cho. They were diagnosed as cutaneous gnathostomiasis by their clinical course and immunological tests. Furthermore, loaches obtained from the Japanese restaurant were investigated, which were imported from China. We suspected Gnathostoma hispidum as the infection source, but no Gnathostoma hispidum were found in loaches except many worms of Nematodes, Pallisentis spp.
