Which parasite has an Operculated egg?
The flukes are oviparous. They lay operculated eggs.
What causes Clonorchis?
How does one become infected with Clonorchis? The eggs of Clonorchis are ingested by freshwater snails. After the eggs hatch, infected snails release microscopic larvae that then enter freshwater fish. People become infected by eating infected raw or undercooked fish containing the larvae.
What are Operculated eggs?
o·per·cu·lat·ed Provided with a lid (operculum); denoting members of the mollusk class Gastropoda (snails), subclass Prosobranchiata (operculate snails), and the eggs of certain parasitic worms such as the digenetic trematodes (except the schistosomes) and the broad fish tapeworm, Diphyllobothrium latum.
What is Clonorchis infection?
Parasites – Clonorchis Clonorchis is a liver fluke parasite that humans can get by eating raw or undercooked fish from areas where the parasite is found. Found across parts of Asia, Clonorchis is also known as the Chinese or oriental liver fluke. Liver flukes infect the liver, gallbladder, and bile duct in humans.

What is Operculum egg?
The operculum is an empty cavity. The chitinous fibers of the egg-shell in this area are diffuse and loose, with numerous micropores or spaces. The egg-shell in this area therefore appears to form a fine tubular network. The oocyte is an undifferentiated cell with a biconcave drum-like shape.
What does Operculated mean?
Are Schistosoma eggs Operculated?
Eggs are round to oval in shape, operculate (hinged at one end) and contain a developing embryonic larva (miracidium).
How is Clonorchis sinensis diagnosed?
Diagnosis of Clonorchis infection is based on microscopic identification of the parasite’s eggs in stool specimens. Safe and effective medication is available to treat Clonorchis infections. Adequately freezing or cooking fish will kill the parasite.
What disease is caused by Opisthorchis Felineus?
Opisthorchiasis is a parasitic disease caused by species in the genus Opisthorchis (specifically, Opisthorchis viverrini and Opisthorchis felineus). Chronic infection may lead to cholangiocarcinoma, a malignant cancer of the bile ducts.
