DNA Multi-Marker Genotyping and CIAS Morphometric Phenotyping of -Sized Flukes from Ecuador, with an Analysis of the Absence in the New World and the Evolutionary Lymnaeid Snail Vector Filter.

Fascioliasis is a disease caused by worldwide transmitted by lymnaeid snails mainly of the / group and restricted to parts of Africa and Asia and transmitted by lymnaeids. Concern has recently risen regarding the high pathogenicity and human infection capacity of . Abnormally big-sized fasciolids were found infecting sheep in Ecuador, the only South American country where has been reported.

Lymnaeid Snail Vectors of Fascioliasis, Including the First Finding of Lymnaea neotropica in Ecuador, Assessed by Ribosomal DNA Sequencing in the Southern Zone Close to the Peru Border.

Purpose: Fascioliasis is a freshwater snail-borne zoonotic trematodiasis of high pathogenicity and wide veterinary repercussions. In South America, moreover, it causes serious public health problems, with high human infection rates in Andean countries. Ecuador offers a worrying risky scenario due to its physiography, including many human infection reports and animal endemicity throughout its Andean highlands.
