Abstract

Fasciola hepatica is a parasite of worldwide distribution that occurs to a greater extent in bovines. During the internship carried out in the Municipal Cattle Bovine Benefit Plant, Pamplona located in the city of Pamplona, in the period between March 13 and June 7, 2019, a longitudinal observational study of the prevalence of the mentioned parasite was carried out. The objective was to determine the prevalence of Fasciola hepatica in cattle slaughtered in the Bovine Cattle Benefit Plant, Pamplona Municipal, for this purpose, during this period a total of 945 cattle were received for slaughter, of which 684 were males and 261 females. Likewise, ante- mortem activities were carried out such as: verification of age, sex, and race of the animals that entered; verification of said data and approval of the slaughter of the animals since they do not show obvious signs of disease. In the post-mortem inspection, verification was made of the general conditions of the red viscera, where morphological changes in the liver and sometimes in the lung could be observed macroscopically due to the presence of bovine Fasciola hepatica. These changes in the liver were characterized by alterations in the Glisson capsule and the hepatic bile ducts and at the pulmonary level, alterations of the parenchyma; where it was possible to observe areas of dark nodular appearance that contained said parasite inside. It should be clarified that a higher prevalence was observed in Normando animals and in females in general.
