Liver fluke parasite
Videonummer 11926078
| Light microscopy of a liver fluke (Fasciola hepatica), a parasitic flatworm. This flatworm can infect the liver of a number of mammals, including humans, causing the disease fascioliasis (or fasciolosis). The flatworms migrate to the liver and block the bile ducts, causing abdominal pain, fever, anaemia and jaundice. The eggs pass through the bile into the gut and exit the body in faeces. The flukes require aquatic snails as an intermediate host, from which they emerge and attach to vegetation, allowing them to be eaten by herbivores. Liver fluke infestation costs billions of pounds worth of damage to the livestock industry each year, and is a growing concern in human health as well. | |
