Gnathostomiasis in remote northern Western Australia: the first confirmed cases acquired in Australia.

A husband and wife became unwell after eating a fish from the Calder River in northern Western Australia. Gnathostomiasis was diagnosed, and treated with ivermectin and albendazole. Serological testing was positive for gnathostomiasis, and there has been no recurrence. These appear to be the first proven endemically acquired cases of gnathostomiasis in Australia, and demonstrate the difficulties in diagnosis and treatment.
