Knowledge of the endoparasitic fauna of Lama guanicoe Muller, 1776, from the Mitre Peninsula, Tierra del Fuego, Argentina

Parasitological fauna of Lama guanicoe in the Peninsula Mitre, Tierra del Fuego, Argentina, is analyzed in this paper. Coproparasitological tests of 58 samples were performed, and on this basis, the presence of the following genera was determined: Haemonchus, Marshallagia, Cooperia, Nematodirus, Ostertagia, Trichostrongylus, Oesophagostomun and Chavertia. Marshallagia and Chabertia are reported for the first time for this host. The dung piles are not considered as parasitic barriers. Infections occur in two seasons: at the beginning of the spring and at the beginning of summer, as a survival strategy of parasitic nematodes. Parasites of L. guanicoe would be secondarily acquired form cattle.
