Orbiidilistele

Orbiidilistele, also known as Orbital Dilistoma, is a parasitic infection caused by the trematode worm Dilistoma nasale. This infection primarily affects humans and is transmitted through the ingestion of contaminated water or food, particularly freshwater fish and shellfish. The life cycle of Dilistoma nasale involves two hosts: the definitive host, which is typically a human, and the intermediate host, which can be various freshwater snails.

The infection begins when a human ingests an encysted metacercaria from contaminated water or food. The metacercaria then migrates to the liver, where it matures into an adult worm. The adult worms can grow to several centimeters in length and can cause significant damage to the liver. Symptoms of orbiidilistele may include abdominal pain, nausea, vomiting, and jaundice. In severe cases, the infection can lead to liver failure and other complications.

Diagnosis of orbiidilistele is typically made through imaging studies such as ultrasound or CT scans, which can reveal the presence of adult worms in the liver. Treatment usually involves the administration of praziquantel, an anthelmintic drug that kills the adult worms. Prevention of orbiidilistele involves proper sanitation, the avoidance of contaminated water and food, and the proper cooking of freshwater fish and shellfish.
