A study on immunodiagnosis of gnathostomiasis by ELISA and double diffusion with special reference to the antigenicity of Gnathostoma doloresi.
In order to diagnose gnathostomiasis immunologically, Gnathostoma doloresi was evaluated for the antigenicity in comparison with G. hispidum which was recently reported in Japan by using micro-ELISA. The study revealed that G. doloresi can be used as the alternate source of antigen in the test. A significant increase of specific IgG antibodies was seen in 22 (73.3%) out of 30 gnathostomiasis cases. Although double diffusion was slightly less sensitive than ELISA, it was considered more specific than the latter method.
