Fasciola hepatica Linnaeus 1758

An egg of Fasciola hepatica (common liver fluke).

This is an illustration of the life cycle of the causal agents of Fascioliasis.Created: 2002

Life cycle of the trematode parasites Fasciola hepatica and F. giganticaImmature eggs are discharged in the biliary ducts and in the stool (1). Eggs become embryonated in water (2) and release miracidia (3), which invade a suitable snail intermediate host (4), including snails in the genera Galba, Fossaria, and Pseudosuccinea. In the snail, the parasites pass through several developmental stages (sporocyst (4a), redia (4b), and cercaria (4c)). The cercariae are released from the snail (5) and encyst as metacercariae on aquatic vegetation or other surfaces. Mammals acquire the infection by eating vegetation containing metacercariae. Humans can become infected by ingesting metacercariae-containing freshwater plants, especially watercress (6). After ingestion, the metacercariae excyst in the duodenum (7) and migrate through the intestinal wall, the peritoneal cavity, and the liver parenchyma into the biliary ducts, where they develop into adults (8). In humans, maturation from metacercariae into adult flukes takes approximately 3 to 4 months. The adult flukes (Fasciola hepatica: up to 30 mm by 13 mm; F. gigantica: up to 75 mm) reside in the large biliary ducts of the mammalian host. Fasciola hepatica infect a variety of mammals, but mostly herbivores.From Centers for Disease Control Parasites and Health website.

Description: English: Hatching of eggs of common liver fluke (Fasciola hepatica) into miracidia (free-living motile form). Fasciola hepatica eggs (in this video) were incubated 15 days in 0.5 cm water layer at 25C in the dark. After 15 days, eggs were exposed to intense light. Fully developed miracidia inside eggs started to hatch within 30 minutes after light exposure. This real-time video was taken using light microscopy at magnification 40x.
