Helminths of Rodents (Rodentia: Muridae) from Metztitlán, San Cristóbal, and Rancho Santa Elena, Hidalgo, Mexico

Abstract

Forty-two rodents, representing 3 murid species (Mus musculus, Peromyscus maniculatus, and Rattus rattus), were collected from 3 sites: Metztitlán, San Cristóbal, and Rancho Santa Elena in Hidalgo, Mexico, and examined for parasites. In all, 13 species of helminths were collected: 10 nematode taxa (Syphacia obvelata, Syphacia muris, Syphacia peromysci, Aspiculuris sp., Gongylonema sp., Trichuris muris, Trichinella sp., Nippostrongylus brasiliensis, Capillaria gastrica, and Carolinensis carolinensis) and 3 cestode taxa (Rodentolepis nana, Taenia taeniaeformis, and Taenia sp.). Nippostrongylus brasiliensis was most prevalent. Aspiculuris sp. was the most intense and abundant, followed by R. nana. All species collected are new geographic distribution records for Hidalgo.
