gnathostomiasis

[nath′ōstōmī′əsis]
Etymology: Gk, gnathos + stoma, mouth + osis, condition
infection with the nematode Gnathostoma spinigerum, occurring when undercooked fish harboring the larvae is eaten. Because of its consumption of raw fish, the population of Southeast Asia, especially residents of Thailand and Japan, are particularly at risk. The larvae migrate, often in the subcutaneous tissue, causing a creeping eruption associated with intense eosinophilia. Occasionally they migrate to deeper tissues and cause abscesses or to the central nervous system, where they cause eosinophilic myeloencephalitis. The infection is treated by surgical removal or treatment with albendazole or ivermectin. See also cutaneous larva migrans.

gnathostomiasis

Infestation with the dog and cat parasitic worm Gnathostoma spinigerum that is common in the Far East. The intermediate hosts are fish and the tiny crustacean water flea Cyclops and the worm is acquired by eating undercooked fish or drinking water containing the flea. The adult worm settles in the tissues and can damage the lungs, kidneys, brain or eyes. The worm may settle visibly under the skin; otherwise the diagnosis is by antibody tests. Treatment is difficult.

gnathostomiasis

infection with the nematodes Gnathostoma spp. contracted by eating the intermediate host, e.g. undercooked fish infected with the larvae of G. spinigerum. Includes gastritis and cysts in the stomach wall caused by the adults and hepatitis caused by the larvae.
