Nematodes in Sceloporus variabilis (Squamata: Phrynosomatidae) in localities in The High Mountains of, Veracruz, Mexico Nematodes in S. variabilis

Abstract

Nematodes were identified in the digestive tract of 11 specimens of the lizard S. variabilis in localities of Las Altas Montanas, Veracruz. Meristic data were obtained and the intestine was dissected to obtain the nematodes, 17 nematodes belonging to the Oxyuridae family were identified. No significant differences were found in the frequency of nematodes between sexes of S. variabilis. Future studies increasing the number of samples, localities and identifying nematodes at the species level using molecular phylogeny methods will help to measure the impact of this type of relationship.

Key words.- absence, frequency, .host, Oxyuridae, parasites.
