The underside of the flukes have unique black/dark gray and white pigmentation patterns, and may have scars and deformities from barnacles, entanglements in fishing gear, and even from attempted predation. The trailing edge can also be used to identify individuals by the unique ridges, notches, scars, and deformities.
Which are characteristics of flukes?
Flukes are leaf-shaped, ranging in length from a few millimeters to 7 to 8 cm. The tegument is morphologically and physiologically complex. Flukes possess an oral sucker around the mouth and a ventral sucker or acetabulum that can be used to adhere to host tissues. A body cavity is lacking.

Do flukes move?
Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. 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 liver parenchyma.
Can you see flukes in stool?
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 flukes contagious?
Liver flukes cannot be spread from person to person. Instead, people and animals get infected with liver flukes by eating contaminated fish or drinking contaminated water.
How are flukes transmitted?
People can get infected with liver flukes after swallowing the parasite, most often by eating raw vegetables or drinking contaminated water.
How do you get rid of flukes?
Lung fluke infections are treated with praziquantel, a drug used to eliminate flukes from the body (called an anthelmintic drug). An alternative is triclabendazole. If the brain is infected, corticosteroids may also be given. They help control the inflammation that develops when the drug kills the flukes.
How big do flukes get?
Intestinal flukes (trematodes) are flat hermaphroditic worms that range in size from a few millimeters to several centimeters. Approximately 70 trematode species have been reported to colonize the human intestinal tract.

How do blood flukes affect the human body?
Schistosomes are water-borne flatworms or blood flukes that enter the human body through the skin. Some symptoms of schistosomiasis include fever, arthralgias, abdominal pain, bloody diarrhea, and hematuria. Ultimately, patients develop heptosplenomegaly, ascites, and lymphadenopathy.
Where is liver fluke found?
Occasionally, liver flukes infect the wall of the intestine, the lungs, the skin, or the throat. Years later, infected people may develop cancer of the biliary ducts. Ultrasonography or MRI/MRCP can usually detect a tumor in the bile ducts or gallbladder.

Praziquantel is the drug of choice for most intestinal fluke infections, although niclosamide has been reported to have some in vitro efficacy.
What is the main difference between flukes and flatworms?
| Flukes vs Tapeworms | |
|---|---|
| Flukes belong to the class trematode, and they are leaf-shaped. | Tapeworms belong to the class cestode, and they are flat, long worms which reside on the intestines. |

The other is a ventral sucker in the middle of the body that helps trematodes hang on to their host. Trematodes have simple sensory organs around the mouth, but do not have some of the more complex sensory organs found in other flatworms, such as the eye spots of turbellarians.
What is the habitat of blood flukes?
Geographic Distribution. Schistosoma mansoni is found primarily across sub-Saharan Africa and some South American countries (Brazil, Venezuela, Suriname) and the Caribbean, with sporadic reports in the Arabian Peninsula. S. haematobium is found in Africa and pockets of the Middle East.
