PREVALENCE OF FASCIOLOSIS (FASCIOLA HEPATICA LINNAEUS, 1758) IN BOVINE SLAUGHTER COMPANIES IN THE PROVINCE OF IMBABURA, ECUADOR

Abstract:

Fasciolosis is a zoonosis caused by the parasite Fasciola hepatica Linnaeus, 1758, which, in order to develop its biological cycle, requires an intermediate host (gastropod mollusk, Lymnaeidae), and a definitive host (mammals, including man). This disease has caused annual economic losses of $200 M in the world. The objective of the present investigation was; to identify the prevalence of F. hepatica in the bovine slaughter centers, to determine the economic losses, and to identify the agroecological characteristics where the intermediate hosts develop, in the province of Imbabura, Ecuador. A prevalence of F. hepatica of 10, 9% was identified, where the Cantón Otavalo presented 190 positive samples (19, 7%), being considered the point with the highest prevalence within the study. The positive bovines were 102 males (26, 9%) and 277 females (73, 1%), which belong to the Mestizo (53, 5%), Holstein (42%) and …
