Caption: Parasitic nematode worm (Ascaris lumbricoides). This worm inhabits the human intestine. An adult female, as seen here, may measure 35 centimetres in length. Infestation with the worms (ascariasis) causes abdominal pain, vomiting, diarrhoea and peritonitis. The female lays up to 200,000 eggs per day, which are excreted in the faeces and ingested by a new host through contaminated water or food. The larvae hatch in the small intestine and travel through the blood to the lungs where they can provoke pneumonia. The juvenile worms migrate up the airway and are swallowed, thereby returning to the intestines to mature. Treatment is with anthelmintic drugs.
