Mendoza province lies to the west of Argentina, its backbone being the Andes Mountains. In its valleys can be found very high endemicities of fascioliasis in cattle , sheep, goats , horses, mules, donkeys and even introduced llamas. Up to the present, such high prevalences were always linked to the presence of only one lymnaeid vector species described in the region, Lymnaea viatrix , similarly as for most of Argentina. However, traditional malacologicalmethods have proven to be insufficient to reach species level classification in the Galba-Fossaria group4 .

El tremátode Fasciola hepatica afecta principalmente a animales herbívoros, y representa una zoonosis de gran importancia. Se encuentra en emergencia y dispersión a nivel global, habiéndose registrado áreas de alta endemia en zonas andinas de Sudamérica. En Argentina, la región de bosque Andino – Patagónico es considerada endémica para la afección. Los vectores Lymnaea son cruciales en la epidemiología y patrones de transmisión, pudiendo ser determinada su presencia por factores climáticos, mayormente temperatura, precipitación y/o evapotranspiración. Se pretende caracterizar, mediante análisis ...

Even though Fascioliasis has been known for centuries, it is now emerging in many parts of the world . Human cases are rising, two decades ago the estimates were of a few thousand , current estimates reach many millions. The human endemic areas are highest in Latin American countries and animal fascioliasis greatly affects livestock all through the region, often of poor subsistence farmers, thus decreasing even more their meager earnings and contributing to the cycle of disease and poverty . The enourmous geographical diversity of the regions affected by fascioliasis in Latin America ranges from ...
