Flukes

Flukes

Flukes (/fluːks/), also known as Trematodes (/ˈtrɛməˌtoʊdz/), are a class of parasitic flatworms belonging to the phylum Platyhelminthes. The term "fluke" comes from the Old English "flōc" meaning "flatfish", due to their flat, oval shape.

Etymology

The term "fluke" is derived from the Old English "flōc", which translates to "flatfish". This is due to the flat, oval shape of these parasites, which resembles that of a flatfish. The term "trematode" comes from the Greek "trematodes", meaning "having holes", which refers to the ventral and oral suckers that these parasites possess.

Description

Flukes are characterized by their flat, oval bodies and the presence of ventral and oral suckers. They are typically small in size, ranging from 1mm to several centimeters in length. Flukes are endoparasites, meaning they live inside their host. They are known to infect various species, including humans, in which they can cause a variety of diseases.

Diseases Caused by Flukes

Flukes are responsible for a number of diseases in humans, including Schistosomiasis, Fascioliasis, and Clonorchiasis. These diseases are typically contracted through contact with contaminated water or the consumption of undercooked, contaminated food.

Schistosomiasis

Schistosomiasis, also known as bilharzia, is a disease caused by parasitic flukes of the genus Schistosoma. It is one of the most prevalent parasitic infections in the world, affecting millions of people each year.

Fascioliasis

Fascioliasis is a parasitic worm infection caused by the liver fluke Fasciola hepatica or Fasciola gigantica. It is primarily contracted through the consumption of contaminated water or food.

Clonorchiasis

Clonorchiasis is a parasitic disease caused by the Chinese liver fluke, Clonorchis sinensis. It is primarily contracted through the consumption of raw or undercooked freshwater fish.

Prevention and Treatment

Prevention of fluke infections primarily involves proper sanitation and food preparation practices. Treatment typically involves the use of antiparasitic medications, such as Praziquantel.
