Hookworm is intestinal nematode parasite of two species

Ancylostoma duodenale


Necaor americanus

These worms attach to the mucosa of the small intestine in order to suck blood and nutriments. The adult worms then produce over 1000 eggs per day which appears feces and is transmitted into another host via skin. Hatched larvae penetrate the skin in shallow waters and then migrate into the lungs through the blood stream, invade the alveoli and then sucked out of the airways only to be swallowed into the food way. They reach the small intestine to establish their parasitism which includes iron deficiency anemia due to costant sucking of blood.
