Resumen
EZQUIAGA, M. Cecilia; ABBA, Agustín M.; CASSINI, Guillermo H. y NAVONE, Graciela T.. Evidences of internal parasites in live animals: a population of Chaetophractus vellerosus (Xenarthra: Dasypodidae) as model of coproparasitological study. Rev. Mex. Biodiv. [online]. 2014, vol.85, n.3, pp.845-853. ISSN 2007-8706. https://doi.org/10.7550/rmb.40472.
The aim of this study was to analyze the parasitic fauna of a population of Chaetophractus vellerosus from Magdalena, Buenos Aires province, Argentina, by parasitological analysis. We evaluated the influence on the parasitic dynamics of different host parameters -age, sex, height and weight- as well as seasonality, vegetation and human impact. Oocysts of 2 species of Eimeria (Protozoa-Coccidea) and eggs of Aspidodera sp. Trichostrongylina, Ancylostoma sp. and Trichuris sp. (Nematoda) were found. Eimeria sp. and Aspidodera sp. were the most prevalent parasites, and Ancylostoma sp. was the lowest prevalent. Parasite loads of coccideans were higher in hosts young. Parasite loads of Trichuris sp. were higher in males. Only Trichostrongylina had greater loads in specimens with poor body condition. Trichostrongylina and Eimeria sp. were most prevalent in summer, while Aspidodera sp. was in winter. Neither vegetation nor human impact influenced in parasitic loads. This study enabled us to know the parasitic fauna of a population of C. vellerosus (Dasypodidae) in Argentina through coproparasitological analysis, and monitor it for 4 consecutive years.
