Abstract:
The Astyanax genus is geographically distributed from the southern of United States of
America to the Negro River in Patagonia. Particularly in Mexico two species are
recognized: A. mexicanus and A. aeneus. These species have been studied for helminths,
and apparently are infected by an exclusively group of parasites, and also by species with
wide host range (generalists). The main objective of this study is to establish a more
precise list of endoparasites species in Astyanax spp along its distribution in Mexico. To
meet this objective, between October 2013 and May 2014, we conducted a survey of
Astyanax spp specimens in 27 locations from 11 states: Campeche, Chiapas, Jalisco,
Michoacán, Morelos, Querétaro, Oaxaca, San Luis Potosí, Tabasco, Veracruz and
Yucatan. The parasites obtained were fixed for morphological and molecular study. The
results suggest that species of Astyanax in Mexico are parasitized by species of the genera
of trematodes Auriculostoma, Clinostomum, Creptotermatina, Magnivitellinum,
Prosthenhystera and Wallinia (Platyhelminthes), as well as by nematodes like
Contracaecum, Procamallanus, Rhabdochona and Spinitectus.
