What is the infective stage of Dicrocoelium dendriticum?
Dicrocoelium dendriticum spends its adult life inside the liver of its host. After mating, the eggs are excreted in the feces. The first intermediate host, the terrestrial snail (Cochlicopa lubrica in the United States), consumes the feces, and becomes infected by the larval parasites.
How do ants become infected with Dicrocoelium dendriticum?
The small liver fluke, Dicrocoelium dendriticum, is a trematode parasite that infects wild and domestic mammals and very occasionally humans. To reach its mammal hosts its complex life cycle relies on first infecting snails and then ants which are ingested by a grazing animal such as a deer or a cow.
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.
What are the symptoms of Fasciola hepatica?
For example, symptoms can result from inflammation and blockage of bile ducts. During both phases of the infection, clinical features can include fever, malaise, abdominal pain, eosinophilia, hepatomegaly (an enlarged liver), and abnormal liver tests.
What are the symptoms of a Dicrocoelium dendriticum infection?
Most infections involve low numbers of flukes and are not associated with overt symptoms. In more intense infections, symptoms may include cholecystitis, liver abscesses, and generalized gastrointestinal/abdominal distress. Occasional cases involving flukes in subcutaneous masses have been reported. Dicrocoelium dendriticum eggs in wet mounts.
Where can you find Dicrocoelium dendriticum in animals?
Dicrocoelium dendriticum, the lancet liver fluke, is found in the bile ducts of sheep, cattle, pigs, deer, cottontail rabbits, and woodchucks ( Georgi, 1985 ). The fluke eggs are eliminated in the feces of the definitive hosts and are ingested by terrestrial snails. Cercaria develop in the snails, are secreted in mucus, and are ingested by ants.
What are the signs and symptoms of dicrocoeliasis?
The signs and symptoms of Dicrocoeliasis vary in occurrence and severity depending on the duration and magnitude of infestation by D. dendriticum. Symptoms that are common for most mild cases of infection include:
Where does d.dendriticum live in the body?
D. dendriticumis distributed worldwide. The adults of D. dendriticumare 5 to 15 mm in length and 1.5–2.5 mm in width. They live in the bile ducts of the definitive host (ruminants such as cow and sheep). The eggs excreted in faeces are mainly ingested by land snails of the Helicella, Theba and Zebrinagenera.
