Ditylenchus destructor is a plant pathogenic nematode commonly known as the potato rot nematode. Other common names include the iris nematode, the potato tuber eelworm and the potato tuber nematode. It is an endoparasitic, migratory nematode commonly found in areas such as the United States, Europe, central Asia and Southern Africa.
Major groups of parasites include protozoans (organisms having only one cell) and parasitic worms (helminths). Of these, protozoans, including cryptosporidium, microsporidia, and isospora, are most common in HIV-infected persons. Each of these parasites can infect the digestive tract, and sometimes two or more can cause infection at the same time.

The first appearance of eggs in stools is 60–70 days. In larval ascariasis, symptoms occur 4–16 days after infection. The final symptoms are gastrointestinal discomfort, colic and vomiting, fever, and observation of live worms in stools. Some patients may have pulmonary symptoms or neurological disorders during the migration of the larvae.
The movement of food through the digestive system is the result of the body movements of the worm. The intestine has valves or sphincters at either end to help control food movement through the body.
Potato cyst nematodes are important economically due to the fact that they can substantially reduce crop yields. Globodera pallida are able to cause 80% yield loss in a potato field if left untreated. [8] On a more global scale, the Australian potato industry is worth about AUD$500 million yearly which equates to $340 million U.S. dollars. [7] [9]

Clinical symptoms are due to the large size of the tapeworm, which often reaches a length exceeding 15 m (49 ft). The most common symptom is pernicious anemia, caused by the absorption of vitamin B 12 by the worm. [5] Other symptoms include various intestinal issues, slight leukocytosis, and eosinophilia.
