Fasciolosis (liver fluke disease) is a zoonosis of significant public health relevance, caused by parasites of the genus Fasciola, specifically of the species Fasciola hepatica, a helminth of the class Trematoda, which exhibits a lanceolate morphology and is involved in the zoonotic cycle through contamination of bodies of water and aquatic vegetation, including watercress, by means of metacercariae, its infective form. Their biological cycle includes a migration phase from the host’s intestine to the liver, where they mature and settle in the bile ducts, causing pathological changes such as direct hepatic lesions, bile duct obstruction and a systemic inflammatory response. Clinically, these events manifest through predominantly hepatic and gastrointestinal symptoms secondary to hepatic involvement, which can escalate to severe complications such as cirrhosis and hepatic abscesses in t...
