A human case of echinostomiasis infected from raw loaches (Misgurnus anguillicaudatus) is reported. A patient, 52-year-old male, had complaints of fever (38.5℃) with high eosinophilia and abdominal pain. The eggs in feces, yellowish-brown and 111.2±7.8×70.1±2.6μm in size, were identified Echinostoma sp.. Twice administration of Kamala, 5g and 10g,respectively, followed with purgative MgSO_3, were tried, but failed to collect adult worms. Comparing with the morphological and epidemiological data of echinostomiasis in Japan, the species of Echinostomatidae in this case could not be identified. In the gel diffusion test and the immunoelectrophoresis, this case was positive for Gnathostoma sp. antigen. As raw loaches may cause echinostomiasis and gnathostomiasis, the preventive measures should be developed from the view point of food safety. This case is the second case of echinostomiasis in Shimane Prefecture.
