Caption: Hookworm. Illustration of a hookworm (Necator americanus) clinging to the lining of a human small intestine. The absorptive finger-like villi of the intestinal wall are shown in section. This parasite, which affects 700 million people worldwide, holds on to the gut with its sharp, rasping mouth and feeds on blood. Heavy infestations of hundreds of worms can cause enough blood loss to kill the victim. Hookworm larvae live in the soil and enter the host through the skin. After migrating through the bloodstream to the lungs they are coughed up, swallowed, and infect the small intestine. They can be killed by anthelmintic drugs.
