CHAVEZ-ARCE, Edel Valkan  y  ZUMARAN, Guido. Frequency of fascioliasis in cattle and Fasciola hepatica in Lymnaeidae snails in the district of Huanca, Arequipa, Peru. Rev. investig. vet. Perú [online]. 2021, vol.32, n.3, e17607. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v32i3.17607.

The aim of this study was to determine the frequency of fascioliasis in cattle and its associated factors, as well as the frequency of infection with larval stages in Lymnaeidae snails in the livestock area of the Huanca district in Arequipa, Peru. In total, 179 samples of bovine, ovine and equine faeces, and 561 Lymnaeidae snails were collected. The associated factors were determined by applying an epidemiological survey for each livestock species, through the interview with the owners. Fasciola hepatica eggs obtained from faecal samples were analysed using the modified four-sieve technique. The snails (n = 484) were crushed on slides to release and analyse the larval stages of the trematode, while 77 snails were processed using the Pointier technique for taxonomic identification. The frequency of Fasciola hepatica in cattle was 46.4%, being higher in sheep and horses, in animals that were fed with alfalfa and natural pastures, and in those that drank water from the ditches and the river. The variable livestock species was established as a factor associated with fascioliasis. The frequency of infection in the Lymnaeidae was 7.4%. The snails belonged to the genus Lymnaea.
