Fasciolopsiasis results from an infection by the trematode Fasciolopsis buski, [1] the largest intestinal fluke of humans, growing up to 7.5 cm (3.0 in) long.
Fasciolopsis buski is the cause of the pathological condition fasciolopsiasis. [3] In London, George Busk first described Fasciolopsis buski in 1843 after finding it in the duodenum of a sailor. After years of careful study and self experimentation, in 1925, Claude Heman Barlow determined its life cycle in humans. [4] [5] [6]
Fasciolosis is a parasitic worm infection caused by the common liver fluke Fasciola hepatica as well as by Fasciola gigantica.The disease is a plant-borne trematode zoonosis, [3] and is classified as a neglected tropical disease (NTD).
Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes.
Liver fluke infections cause serious medical and veterinary diseases. Fasciolosis of sheep, goats and cattle, is the major cause of economic losses in dairy and meat industry. [5]
Fasciola pass through five phases in their life cycle: egg, miracidium, cercaria, metacercaria, and adult fluke. [2] The eggs are passed in the feces of mammalian hosts and, if they enter freshwater, the eggs hatch into miracidia.
Fasciolidae is a family of trematodes and includes several parasites involved in the veterinary and medical sciences, which cause the disease Fasciolosis.Fasciolidae is divided into five genera by Olson et al. 2003.
Fasciola gigantica causes outbreaks in tropical areas of South Asia, Southeast Asia, and Africa.The geographical distribution of F. gigantica overlaps with F. hepatica in many African and Asian countries and sometimes in the same country, although in such cases, the ecological requirement of the flukes and their snail hosts are distinct.
