What is the recommended treatment for Dicrocoelium dendriticum?
Because human infections with Dicrocoelium dendriticum are so rare, there are multiple suggestions for treatment. The standard treatment is an anthelmintic such as Praziquantel, Triclabendazole, or Mirazid.
How does Dicrocoelium dendriticum cause disease?
The lancet fluke infection is caused by D. dendriticum in sheep, goats, deer and humans. The adult worms live in the bile duct of the host giving rise to various liver troubles. The disease is acquired by ingestion of metacercariae while snails and ants serve as the intermediate hosts in the worm’s life cycle.
Is Dicrocoelium a trematode?
The trematode Dicrocoelium dendriticum, the lanceolate fluke or lancet fluke, is a common parasite of ruminants but humans can be accidental definitive hosts. Another species, D. hospes, is responsible for human infections in West Africa.
How many hosts does Dicrocoelium dendriticum have in its life cycle?
The Lancet liver fluke (Dicrocoelium dendriticum) has a rather complex life cycle that includes two intermediate hosts and one definitive host.
Which life cycle stage of Dicrocoelium dendriticum infects enters penetrates the first intermediate host?
The life cycle of D. dendriticum involves a pulmonate terrestrial snail as first intermediate host. The miracidia emerge from an egg after ingestion by a snail in which they penetrate the hepatopancreas and form first-generation sporocysts.
Where do larvae of lancet fluke penetrate into ants?
Once the ant, and therefore the metacercariae, are ingested, the metacercariae excyst in the duodenum (the first part of the small intestine immediately beyond the stomach). These juveniles penetrate blood vessels and travel up the common bile duct to the capillaries of the liver.
What causes Fasciola hepatica?
Fascioliasis is caused by two species of parasitic flatworms or trematodes that mainly affect the liver. The two species of trematodes that cause fascioliasis (Fasciola hepatica and Fasciola gigantica) are leaf-shaped worms, large enough to be visible to the naked eye (adult F.
What is slime ball in parasitology?
(helminthology, specifically) A mucus-coated lump containing the cercariae (“parasitic larvae”) of a liver fluke (of the phylum Platyhelminthes). quotations ▼
Are all trematodes parasitic?
What do Lancet liver fluke eat?
Dicrocoelium dendriticum (or the lancet liver fluke) is a parasitic flatworm. During the course of its remarkable life cycle it inhabits snails, ants and herbivorous mammals such as cattle.
What does Dicrocoelium dendriticum eggs look like?
Dicrocoelium dendriticum eggs in wet mounts. Eggs of Dicrocoelium dendriticum are operculated and measure 35-45 µm long by 20-30 µm wide. The eggs are thick-shelled and usually dark brown in color. Eggs are fully embryonated when shed in feces.
Where is Dicrocoelium dendriticum found?
Dicrocoelium Dendriticum. Dicrocoelium dendriticum, the lancet liver fluke, is found in the bile ducts of sheep, cattle, pigs, deer, cottontail rabbits, and woodchucks (Georgi, 1985).
What are the symptoms of Dicrocoelium dendriticum?
In heavier infections, symptoms may include cholecystitis, liver abscesses and upper abdominal pain. Eggs of Dicrocoelium dendriticum are operculated and measure 35-45 µm long by 20-30 µm wide. The eggs are thick-shelled and usually dark brown in color. Eggs are fully embryonated when shed in feces.
What is dendriticum?
Dicrocoelium dendriticum, the lancet liver fluke, is a parasite fluke that tends to live in cattle or other grazing mammals.
