Distribution of Fasciolopsis buski. F. buski is endemic in Asia including China, Taiwan, Southeast Asia, Indonesia, Malaysia, and India. It has an up to 60% prevalence in worst-affected communities in southern and eastern India and mainland China and has an estimated 10 million human infections. Infections occur most often in school-aged ...
Fasciolopsis (/ ˌ f æ s i oʊ ˈ l ɒ p s ɪ s, f ə ˌ s aɪ-/ [1] [2]) is a genus of trematodes. They are also known as giant intestinal flukes. Only one species is recognised: Fasciolopsis buski. It is a notable parasite of medical importance in humans and veterinary importance in pigs. It is prevalent in Southern and Eastern Asia.
The cause of this is unknown, and it is also difficult to distinguish between the different species of fasciola as well as distinguishing them from echinostomes and Fasciolopsis. [4] Most immunodiagnostic tests detect infection with very high sensitivity, and as concentration drops after treatment, it is a very good diagnostic method. [ 4 ]
Intestinal flukes infect the gastrointestinal tract and can be caused by the species such as Fasciolopsis buski, Echinostoma, Metagonimus, Heterophyes, and Gastrodiscoides. [12] [5] Lung flukes, mainly the genus, Paragonimus, infect the lungs of organisms, causing infections that can last for up to 20 years in humans.
[5] [8] [6] Several other lymnaeid snails may be naturally or experimentally infected with F. hepatica, but their role in transmission of the fluke is low. [5] The list of lymnaeid snails that may serve as natural or experimental intermediate hosts of F. hepatica include: [9] Austropeplea ollula; Austropeplea tomentosa; Austropeplea viridis ...

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.
