Abstract

MORENO, Pablo G et al. La comunidad de parásitos gastrointestinales de guanacos silvestres (Lama guanicoe) de la reserva provincial La Payunia, Mendoza, Argentina. Mastozool. neotrop. [online]. 2015, vol.22, n.1, pp.63-71. ISSN 0327-9383.

The parasite community of wild vertebrate hosts is composed of several species, but the natural structure of these communities is currently being affected by habitat fragmentation and the introduction of exotic species. The aim of this work was to identify, through the recognition of immature stages in feces, the gastrointestinal parasite species present in the migratory wild guanaco population from La Payunia Reserve (Mendoza). Feces of 756 individuals, collected between 2009 and 2012, were analyzed. The gastrointestinal parasite community of this guanaco population consisted of at least 11 species. Parasites belonged to 5 nematode species: 2 of Nematodirus, 1 of Trichuris, 1 of Capillaria, and 1 of Strongyloides; 1 cestode species corresponding to Moniezia benedeni; and 5 protozoan species of the genus Eimeria (E. lamae, E. alpacae, E. punoensis, E. macusaniensis, and E. ivitaensis). Nematodirus spp., Strongyloides sp., and the detected spe­cies of Moniezia are typical parasites of livestock, and their presence reflects the guanaco susceptibility to be parasitized by them. We suggest conducting parasitological surveys periodically to be able to anticipate to an important rise in this type of parasitism in wild guanacos.
