title: Precocity of Gnathostoma turgidum in naturally infected four-eyed opossum Philander opossum pallidus from Temascal, Oaxaca, Mexico.
abstract: Two female advanced third-stage larvae of Gnathostoma turgidum recovered from the liver of one naturally infected four-eyed opossum Philander opossum pallidus collected in Oaxaca, Mexico, were morphologically examined. Because of some characteristics, the larvae do not fit into the typical advanced third-stage. The body shows a size at least three times larger than expected and rows of spines only in the anterior part of the body surface. Consequently, in this research, we document for the first time the precocity in third-stage larvae of G. turgidum, and we also highlight some facts about the fourth larval stage occurring in spirurins.
