Parasitic nematode worms Featured 24 Jun 2002 Print

Parasitic nematode worms

Nematode worms Ascaris lumbricoides. These worms are the largest of the human intestinal parasites; an adult female may measure 35cm in length. Infestation with the worms, called ascariasis, cause abdominal pain, vomiting, constipation, diarrhoea, appendicitis and peritonitis. The sexually mature worm lives in the small intestine, where the female lays a quantity of eggs. These are excreted in the faeces & ingested by a new host through contaminated water or food. The larvae hatch in the small intestine, migrate through the blood & enter the lungs where they can provoke pneumonia. They enter the mouth, are swallowed & return to the intestines to mature
