MORIENA, R.A; ORTIZ, M.I; RACIOPPI, O  and  ALVAREZ, J.D. Falibilidad de la coprología para diferenciar huevos de Fasciola hepatica y Taxorchis schistocotyle en carpinchos (Hydrochaeris hydrochaeris). Rev. vet. [online]. 2012, vol.23, n.2, pp.147-148. ISSN 1669-6840.

The purpose of this study is to present the fallibility of the coprologic standard method to determine the presence of the trematode Fasciola hepatica in capybara (Hydrochaeris hydrochaeris). For this purpose, 164 samples were analyzed by coprology and a total of 21 cases (12.8%) were positives, but the eggs found were consistent with the morphology and size of both F. hepatica and Taxorchis schistocotyle, fluke parasites of this rodent, with localization in liver and intestine, respectively. For both types of eggs it was no possible to make morphological differentiation when considering size and shape. As a conclusion, fasciolosis prevalence rates obtained from results using the coprology standard method in capybaras may be considered as doubtful, as the technique does not allow differentiating between F. hepatica and T. schistocotyle eggs.

Keywords : Fasciola hepatica; Taxorchis schistocotyle; Hydrochaeris hydrochaeris; Coprology.
