guinea worm

A nematode worm (Dracunculus medinensis) that is a parasite affecting subcutaneous tissues of humans and animals, found in tropical Africa and South Asia. The worm causes infection when its larvae are drunk in unfiltered or unsanitary water. The larvae enter the body through the stomach or duodenum, migrate through internal organs, and become adults. After mating, the adult female burrows to the subcutaneous tissue, often of the leg. The worm has been eradicated in Asia. See: Medina worm See: illustration
