Hookworm Infection

(Ancylostomiasis)

A Ancylostomiasis is an infection with hookworm Ancylostoma duodenale or Necator americanus. The symptoms consist of a rash at the site of larval entry and occasionally abdominal pain or other gastrointestinal symptoms during early infection. Later, iron deficiency may develop due to chronic blood loss. Hookworms are a major cause of iron deficiency anemia in endemic areas. The diagnosis is made by the detection of eggs in the stool. The treatment is carried out with albendazole or mebendazole.

The treatment is carried out with albendazole or mebendazole. Pathophysiology Both hookworm species have a similar life cycle. Excreted in the feces eggs hatch within 1-2 days (when they are deposited on a warm, moist place on loose soil) and release rhabditiforme larvae molt once, only to be slim within 5-10 days to develop filamentous larvae. The larvae can survive three to four weeks if the environmental conditions are favorable. Thread-like larvae penetrate human skin when people walk barefoot on contaminated soil. The larvae reach through the blood vessels, the lungs, penetrate into the pulmonary alveoli, ascend the bronchial tree to the epiglottis high and be swallowed. The larvae develop in the small intestine into adult worms, where they attach to the wall and feed on blood. Adult worms can live two years ?. Life cycle of the hookworm.
