Nematodes in Sceloporus variabilis (Squamata: Phrynosomatidae) in localities in the Altas Montañas region of Veracruz, Mexico

Abstract

Objective: Identify nematodes of the digestive tract of the lizard Sceloporus variabilis.Methodology: In different localities in the Altas Montañas region, 11 individuals of S. variabilis were collected and a range of morphological characteristics measured. Their intestines were dissected to identify the nematodes present.Results: Were identified 17 nematodes belonging to the Oxyuridae family, present in the lizard S. variabilis. Not found differences in the frequency of nematodes between sexes and localities.Implications: Identification of nematodes in S. variabilis is basic information for the knowledge of the parasite-host relationship.Conclusions: The nematodes of the Oxyuridae family may cause mechanical symptoms in S. variabilis.
