Genetic characterization of Fasciola hepatica (Linnaeus, 1758) in cattle from Parana, Brazil.

ABSTRACT: Fasciolosis is a foodborne anthropozoonotic disease caused by Fasciola spp. that affects multiple hosts worldwide. Genetic characterization studies have revealed considerable diversity within F. hepatica populations owing to human and animal migration and intermediate snail hosts. Molecular markers such as microsatellites and mitochondrial DNA sequences are useful tools for assessing parasite population dynamics and evolutionary history. In this study, 16 F. hepatica samples were analyzed using cytochrome c oxidase 1 (CO1) and nicotinamide dehydrogenase (NADH) genes. Parasites were collected from the livers of naturally infected cattle originating from 14 municipalities in Paraná, Brazil. Both CO1 and NADH sequences showed high homogeneity, with mean genetic distances <1% (0.0084 and 0.009
