Giant kidney worm

Giant Kidney Worm (Dioctophyme renale) is the largest nematode (roundworm) that can infect humans. The worm is usually found in the kidneys of carnivorous animals, but can also infect humans through the ingestion of infected raw or undercooked fish or frogs.

Life Cycle

The life cycle of the Dioctophyme renale involves several stages. The adult worms live in the kidneys of the definitive host, where they produce eggs that are passed in the urine. These eggs are then ingested by an intermediate host, typically an annelid worm. The eggs hatch in the annelid, and the larvae develop until they are ingested by the definitive host, completing the cycle.

Symptoms and Diagnosis

In humans, infection with the giant kidney worm can cause a variety of symptoms, including pain in the side or blood in the urine. In severe cases, it can lead to kidney damage or failure. Diagnosis is typically made through the identification of eggs in the urine, or through imaging techniques such as ultrasound or computed tomography (CT) scans.

Treatment

Treatment for Dioctophyme renale infection typically involves surgical removal of the worm. In some cases, antiparasitic drugs may also be used.

Prevention

Prevention of giant kidney worm infection primarily involves avoiding the consumption of raw or undercooked fish or frogs. Proper cooking or freezing of these foods can kill the larvae and prevent infection.
