Geographic range: Human blood flukes live in the warm regions of the world, especially South America, Africa, the Caribbean, and the Middle East. Habitat: The larvae of human blood flukes live in freshwater snails. The adults live in veins in the abdomens of mammals such as rodents, dogs, cattle, baboons, and humans.

Where are trematodes found?
Trematodes typically infect the intestines, lungs, or liver, but migrating species, such as Fasciola and Paragonimus, has been found outside these typical sites, in vital organs such as the eyes or brain, where severe manifestations are reported (WHO, 1995).
Where do flukes live?
Flukes can be found in any place where untreated human waste is utilized as manure. Few flukes (Fasciola hepatica) live on the gills, skin, or outside of their hosts, while others, like blood flukes (Schistosoma), live inside their hosts.
How do trematodes eat?
Trematodes are parasitic flatworms commonly known as flukes. These flattened oval or worm-shaped creatures feed off their hosts' blood using muscular, pumping mouths — as they have no anuses, their bodily wastes blurt out from their mouths as well.

How do trematodes move?
Trematodes, or flukes, are another class of helminths that have parasitic species. Adult flukes are typically flat, oval-shaped worms that have a layer of muscles just below the tegument, or skin, that allow the worm to expand and contract its shape and, thus, move its body.
What fluke looks like?
The symmetrical body of a fluke is covered with a noncellular cuticle. Most are flattened and leaflike or ribbonlike, although some are stout and circular in cross section. Muscular suckers on the ventral (bottom) surface, hooks, and spines are used for attachment.
Can humans get flukes?
Liver flukes are parasites that can infect humans and cause liver and bile duct disease. There are two families of liver flukes that cause disease in humans: Opisthorchiidae (which includes species of Clonorchis and Opisthorchis) and Fasciolidae (which includes species of Fasciola).
Can you poop out liver flukes?
Diagnosis of Fluke Liver Infections
Doctors diagnose Clonorchis, Opisthorchis, or Fasciola infections when they see fluke eggs in a person's stool (feces) or in the contents of the person's intestines. However, finding eggs in stool may be difficult.
Are all trematodes Digenetic?
Digenetic trematodes comprise most of the known trematodes and include those of greatest economic importance. This group is generally referred to as the flukes and is endoparasitic in all classes of vertebrates. Flukes are typically hermaphroditic, but some members are dioecious.
Can humans poop worms?
Intestinal worms can also cause a rash or itching around the rectum or vulva. In some cases, you will pass a worm in your stool during a bowel movement. Some people may have intestinal worms for years without experiencing any symptoms.
What fluke means?
A fluke is an unexpected stroke of good luck. It was a fluke to find that fifty dollar bill on the ground, and it made you smile for the rest of the day. ... If something good happens to you by chance when you're not expecting it, that's a fluke. The word fluke can also be used in a negative or insulting way.
What are Operculated eggs?
A total of 460 eggs were isolated of which 108 (30.7%) were operculated, meaning that they were freshly laid eggs, which had not hatched before the host died.
What is the life cycle of trematodes?
There are three distinct larval stages involved in all digenetic trematode life cycles: the miracidium, sporocyst, and cercaria. Some taxa also produce rediae and/or encysted metacercariae. All of these life stages except for the miracidium can be found in first intermediate hosts.
What species belong to trematodes?
Trematoda (Flukes)
Trematodes are flatworms with female and male reproductive organs in the same individual, and with an incomplete digestive tract. Trematodes significant for dogs belong to the Digenean subclass with a mollusk intermediate host mandatory in the life cycle.
