Abstract

The endoparasitic fauna of four mammal species was analyzed: Puma concolor (Linnaeus, 1771) (cougar), Lycalopex gymnocercus (Fischer, 1814) (grey fox), Myocastor coypus (Molina 1782) (coipus) and Tolypeutes matacus (Linnaeus, 1758) (armadillo). These specimens entered the Center for Wildlife Rehabilitation, Environmental Education and Responsible Recreation located in the province of San Juan, Argentina. Out of the four mammal species, three died on the spot. The necropsy of L. gymnocercus, M. coypus and T. matacus was carried out, and it was evidenced the presence of three species of parasitic nematodes: Physaloptera clausa Rudolphi, 1819 (Physalopteridae) in L. gymnocercus; Trichuris myocastoris Enigk, 1933 (Trichuridae) in M. coypus; and adult females of Aspidodera sp. Railliet & Henry, 1912 in T. matacus. Regarding P. concolor, the expulsion of nematodes was orally, determining the presence of Toxascaris sp. Linstow, 1902 larvae (Toxocaridae). Metric and morphological data of the evidenced nematodes are presented. The present work mentions four new parasite-host interactions for Argentina, and the first records for the province of San Juan, thus contributing to the knowledge of parasites in mammals.
