Radiological Imaging Features of Fasciola hepatica

  1. Fascioliasis refers to a zoonosis caused by Fasciola hepatica, a trematode infecting herbivores, but also occurs in humans who ingest the metacercaria found in fresh water plants. Infection in humans is common in developing countries and is also not uncommon in Europe
  2. Fasciola is a dorso-ventrally flattened, soft, leaf like oval shaped endoparasite. It is about 1.8 to 3.0 cm long, with a maximum width of 0.4 to 1.5 cm. which is a little in front of the middle region of body. Anterior end is somewhat broad and rounded, while posterior end is bluntly pointed

Fasciola hepatica (L., fasciola = small bandage; Gr., hepar = liver), the sheep liver fluke, lives as an endoparasite in the bile passages of sheep Characteristics of the organism and its antigens Fasciola hepatica has an indirect life cycle. Many mammals, including sheep, cattle, rodents, marsupials and humans, can act as definitive hosts. Adult liver flukes, which are about 10 mm wide and 25 mm long, live in the bile duct, feeding on blood, bile and epithelial cells

In other words, India and southeast Asia. rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground The life cycle and transmission features of F. hepatica by L. neotropica of Uruguay were studied under standardized experimental conditions to enable a comparison with the transmission capacity of F. hepatica by Galba truncatula at very high altitude in Bolivia. On this baseline, we reviewed the 95 human fascioliasis cases reported in Uruguay.

Fascioliasis is a zoonotic disease and its causative agents are parasites, Fasciola hepatica and F. gigantica, flatworms or trematodes that mainly affect the liver. They are leaf-shaped worms, large enough to be visible to the naked eye i.e. adult F. hepatica measure 2-3 cm x 1.3 cm while adult F. gigantica measure 2.5-7.5 cm x 1.2 cm) Fasciola hepatica is the common liver fluke of sheep. It is the first trematode whose life history was described by Thomas in 1883. It is of much importance as it causes fascioliasis—a disease that causes damage to liver- tissues and bile ducts of sheep The Adult Worm - Averaging 30mm in length and 13 mm in width, Fasciola hepatica is one of the largest flukes in the world. The adult worm has a very characteristic leaf shape with the anterior end being broader than the posterior end and an anterior cone-shaped projection ADVERTISEMENTS: In this article we will discuss about the structure of Liver Fluke (Fasciola Hepatica) with the help of a diagram. 1. It is commonly known as Liver fluke and is an endoparasite in the bile duct of sheep's liver. ADVERTISEMENTS: 2. It is cosmopolitan and pathogenic and measures about 20 to 50 mm in [ The current study aimed to find out the morphometric and genotypic divergences of the flukes isolated from different hosts in a newly emerging focus of human fascioliasis in Iran. Adult <i>Fasciola</i> spp. were collected from 34 cattle, 13 sheep, and 11 goats from Kohgiluyeh and Boyer-Ahmad province, southwest of Iran. Genomic DNA was extracted from the flukes and PCR-RFLP was used to.

Fascioliasis, a food- or water-borne trematodiasis due to infection by Fasciola hepatica (Fh) or F. gigantica (Fg), is currently believed to affect as many as 17 million people worldwide, 12 with 91.1 million individuals at risk for infection. 4 Fasciola hepatica infects humans on all continents (except Antarctica), having the widest. Fasciola hepatica and Fasciola gigantica are two main species of Fasciola which infect both human and animals. While F. gigantica is occurring mainly in tropical and F. hepatica in temperate areas, both species overlap in subtropical zones [ ]. e two species have been traditionally classied based on their morphological features, such as body. Liver fluke (Fasciola hepatica) is a widespread parasite of ruminants which can have significant economic impact on cattle production. Fluke infection status at the animal-level is captured during meat inspection of all animals processed for human consumption within Northern Ireland. These national datasets have not been analysed to assess their utility in uncovering patterns in fluke. Passive intraperitoneal transfer of sera from Fasciola hepatica‐infected sheep, cattle or rats can protect naive rats from F. hepatica infection, suggesting a parasite killing mechanism within the peritoneal cavity that is dependent on the presence of parasite‐specific antibody. We investigated antibody‐dependent cell‐mediated cytotoxicity by resident peritoneal lavage cell populations. The most common liver fluke species affecting the cattle was Fasciola gigantica, 9.1% of cattle were infected with F. gigantica while, Fasciola. hepatica, mixed infections and unidentified or immature forms of Fasciola spp. were present in 3.2 %, 0.7% and 1 % of cattle, respectively

Cómo citar Fasciola hepatica is considered an emergent human pathogen, causing liver fibrosis or cirrhosis, conditions that are known to be direct causes of cancer. Some parasites have been categorized by WHO as carcinogenic agents such as Opisthorchis viverrini, a relative of F. hepatica. Although these two parasites are from the same class (Trematoda), the role of F. hepatica in carcinogenesis is unclear Hepatic fascioliases are zoonoses, caused mainly by the trematode Fasciola hepatica and Fasciola gigantica, also called liver flukes. 1 These parasites infect the main bile ducts and gallbladder of animals and humans. 1 Both species follow a two-host life cycle, where definitive hosts are humans or other mammals (mainly livestock), and intermediate hosts are freshwater gastropod snails of the. Infections caused by Fasciola species can be diagnosed by microscopic stool examination; however, immunologic techniques, such as enzyme-linked immunosorbent assay, play a more important role because they have 100% sensitivity and 97.8% specificity for fascioliasis.7 In this case, the stool analysis was negative for ova and parasites. Pathologically, liver flukes can be distinguished from one.
