The aim of the study was to identify antibodies against Fasciola hepatica in cattle from the municipality of Chiquinquirá, Boyacá. A descriptive cross-sectional study was carried out in which blood samples were collected from 380 female cattle. Blood serums were processed by the indirect ELISA technique using the commercial Fasciola hepatica Antibody Test Kit (IDEXX™). The general seroprevalence found was 67.37%, where animals older than 4 years (70.2%) and Jersey breed animals (84.4%) presented a higher percentage of seropositivity. The leasing of pastures and the use of cisterns as a source of drinking water showed statistical association with the presentation of Fasciola hepatica, so they were established as risk factors.

The aim of this study was to determine the prevalence of hepatic dystomatosis in cattle slaughtered in the Sogamoso slaughterhouse (Boyacá, Colombia), and to define the most effective diagnostic technique to establish the presence of the parasite. A sample size of 343 individuals was established considering the monthly slaughter rate of the plant. Stool, blood and bile samples were taken, and adult parasites were collected from the bile duct. The modified Ritchie technique was used in the coproparasitological examination, the bile content was analyzed by sedimentation and a standardized in-house ELISA was implemented for serological diagnosis from adult Fasciola hepatica parasites. The results showed that 29.7% (102/343) of the individuals sampled were positive for the presence of F. hepatica in at least one of the techniques used. The post mortem evaluation presented the highest value ...
