| Popis: | In order to clarify the role of Gnathostoma turgidum as an etiological agent involved in human gnathostomiasis in Mexico, establish the taxonomic identity of the advanced third-stage larvae (AdvL(3)), and contribute to the knowledge of its life cycle, experimental host infections, examination of potential natural hosts, and morphological comparisons were carried out. Examination of ten species of potential hosts at San Pedro las Playas and Tres Palos Lagoon in Guerrero state, Mexico revealed that two (Kinosternon integrum and Rana zweifeli) were infected by 15 AdvL(3) of G. turgidum. A specific identity was obtained comparing these larvae with those recovered from hosts experimentally infected. The AdvL(3) measured 1.6 mm in length, with two cervical papillae (both in 12th row) and an excretory pore on the 19th row. The average of cephalic hooklets, from first to fourth row, was 30.8, 34.0, 36.7, and 39.6, respectively. This is the first record of AdvL(3) of G. turgidum in America, and it represents a significant contribution for the understanding of the life cycle of this species. |
