(pinworm) n. a parasitic nematode worm of the genus Enterobius (Oxyuris), which lives in the upper part of the human large intestine. The threadlike female worm, some 12 mm long, is larger than the male; it emerges from the anus in the evening to deposit its eggs, and later dies. If the eggs are swallowed and reach the intestine they develop directly into adult worms. Threadworms cause *enterobiasis, a disease common in children throughout the world.
A common infestation with a small worm, ENTEROBIUS VERMICULARIS (pinworm), that lives in the intestines. Threadworms primarily affect children. The female adult threadworms are white and about 1 cm long (large enough to see). They lay eggs in the skin around the anus, and their movements cause tickling or itching in the anal region, often at night. Eggs are transferred from the fingers to the mouth to cause reinfestation or are carried on toys or blankets to other children. Swallowed eggs hatch in the intestine and the worms reach maturity after a period of 2–6 weeks. Diagnosis is made by seeing the worms or by applying a piece of sticky tape to the anal area to collect the worms or eggs. Treatment is with an anthelmintic drug.... threadworm infestation
