Eustrongylidosis

Eustrongylidosis is a parasitic disease caused by the nematode Eustrongylides. This disease primarily affects waterfowl, fish, and amphibians, but can also infect humans who consume raw or undercooked fish containing the parasite's larvae.

Etiology

The causative agent of eustrongylidosis is the nematode Eustrongylides. This parasite has a complex life cycle involving two intermediate hosts. The first intermediate host is a small aquatic invertebrate, typically a copepod. The second intermediate host is a fish or amphibian, in which the parasite encysts and waits to be consumed by a definitive host.

Symptoms and Diagnosis

In waterfowl, symptoms of eustrongylidosis can include weight loss, anemia, and a distended abdomen. In severe cases, the disease can cause death. Diagnosis is typically made by identifying the parasite in the feces or tissues of the infected animal.

In humans, symptoms can include abdominal pain, nausea, and vomiting. The disease can be diagnosed by identifying the parasite in stool samples or during endoscopy.

Treatment and Prevention

Treatment for eustrongylidosis typically involves the use of anthelmintic drugs to kill the parasite. In severe cases, surgical removal of the parasite may be necessary.

Prevention of eustrongylidosis involves avoiding the consumption of raw or undercooked fish. In areas where the disease is common, fish should be thoroughly cooked or frozen before consumption to kill any parasites.
