Pinworms (Enterobius vermicularis) - roundworms (nematodes) 5-8 mm in length - are causative agents of enterobiasis, a disease characterized by anal itching, urticaria, abdominal pain, and immunosuppression. Children are more frequently affected. Infection occurs through ingestion of pinworm eggs from hands or objects in the surrounding environment, including water. Pinworm eggs enter the aquatic environment from an infected person. Infectious dose - 3-5 eggs
