| Research Abstract |
"New creeping disease" in our project title means the human gnathostomiasis recently prevalent in Mexico . Human gnathostomiasis tends to be endemic in Southern and Eastern Asia such as Thailand and Japan. However, the first case of this disease in Latin America was reported in Mexico by Pelaez & Perez-Reyes (1970), subsequently, over 1300 cases of human gnathostomiasis have been observed in Sinaloa, Nayarit, Guerrero, Oaxaca, Veracruz, Tamaulipas states in Mexico which is now the most endemic country in the world for this disease. Moreover, the prognosis of the Mexican gnathostomiasis was confirmed to be worse than that of the recent Japanese gnathostomiasis caused by G.hispidum and G.doloresi infection, On the other hand, it has been proved that the ELISA using the adult antigen of G.doloresi in Japan is useful for diagnosis of the Mexican gnathostomiasis patients.
In addition, we clarified that the Mexican gnathostomiasis was caused by a new species. G.binucleatum infection, and the final host of this species in Mexico was wild carnivores such as ocelot.
As we fortunately obtained one male and one female of G.turgidum from an opossum Didephis virginiana, the morphology of the adults and eggs of this nematode was observed by light and stereo electron microscopy.
