Fasciolosis. 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). [4][5] It affects humans, but its main host is ruminants such as cattle and sheep. [4]
Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of the very closely related Fasciola hepatica liver fluke, but that is largely inconsequential since treatment is essentially identical for both.
However, due to intermittent egg shedding, multiple stool samples may be necessary for an accurate diagnosis. The WHO recommends the Kato-Katz technique as the method of choice for fascioliasis diagnosis attending to its ease of use and reproducibility, and its enhanced sensitivity compared with the observation of eggs in fresh faeces.
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. It infects the livers of various mammals , including humans, and is transmitted by sheep and cattle to humans all over the world.
Cobbold, 1855 [1] Fasciola gigantica is a parasitic flatworm of the class Trematoda, which causes tropical fascioliasis. It is regarded as one of the most important single platyhelminth infections of ruminants in Asia and Africa. The infection is commonly called fasciolosis. The prevalence of F. gigantica often overlaps with that of Fasciola ...
The life cycle of a typical trematode begins with an egg. Some trematode eggs hatch directly in the environment (water), while others are eaten and hatched within a host, typically a mollusc. The hatchling is called a miracidium, a free-swimming, ciliated larva. Miracidia will then grow and develop within the intermediate host into a sac-like ...
Fasciola hepatica Egg of Dicrocoelium sp. Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. [1] They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and ...
Trematodiasis is a group of parasitic infections due different species of flukes, the trematodes. [4] Symptoms can range from mild to severe depending on the species, number and location of trematodes in the infected organism. [1] Symptoms depend on type of trematode present, and include chest and abdominal pain, high temperature, digestion ...
