Abstract
As a part of an ongoing project to understand the current distribution of Gnathostoma species in Mexico, 22 species of vertebrates were examined for this nematode in the state of Colima. The fish species Dormitator latifrons ("chococo") and Sciades guatemalensis ("cuatete") from Cuyutlán Lagoon and the reptile Crocodylus acutus from the Amela Lagoon were positive for infection. Morphometric characteristics of the larvae collected in Colima were similar to those of G. binucleatum larvae collected from other regions and host species in Mexico. The low divergence of the ITS sequence obtained in this study from that of G. binucleatum (0.19%) indicates that our mater...
