Also known as the “common liver fluke” and “sheep liver fluke,” Fasciola gigantica , is one of two Fasciola trematode species to infect the livers of both animals and humans ( F. hepatica is the other species); F. gigantica is primarily found in domestic and wild ruminants. F. gigantica flukes are approximately 75mm by 15mm in size. Fascioliasis, the term used for clinical disease caused by F. gigantica , is considered a neglected tropical disease. F. gigantica has demonstrated long-term survival due to their adaptivity to the host’s immune system.
