| Popis: | The advanced third-stage larvae (AdvL(3)) of Gnathostoma lamothei was obtained from experimental hosts. Frogs Lithobates heckscheri and snakes Nerodia fasciata pictiventris were compatible hosts allowing optimal larval development. AdvL(3) are 4,487.94 μm long, have two lateral cervical papillae between rows 10 and 16 and an excretory pore at row 23. The average counts of the cephalic bulb hooklets from the four rows are 39.3, 43.3, 44.2, and 47.3. Larvae show an esophagus that represents 40 % of the body width. These findings indicate that amphibians and reptiles could be involved as G. lamothei natural hosts; nevertheless, their role as etiological agents of human gnathostomiasis is uncertain. This paper reports for the first time the taxonomic description of G. lamothei AdvL(3) obtained from experimental hosts and contributes to the understanding of its life cycle. |
