Final answer:
The hookworms associated with iron deficiency anemia are Ancylostoma duodenale and Necator americanus. These nematodes enter the body through the skin and cause symptoms including abdominal pain and anemia, particularly affecting regions with poor sanitation.
Step-by-step explanation:
Hookworms and Iron Deficiency Anemia
The hookworms associated with iron deficiency anemia are Ancylostoma duodenale and Necator americanus. These parasitic nematodes are transmitted through soil contaminated by animal feces where their larvae can penetrate human skin.
Once inside the body, they travel to the lungs and are eventually swallowed to mature in the small intestine. Their presence in the intestines causes nutrient depletion, particularly iron, leading to anemia. While Necator americanus is primarily found in the Americas and Australia, Ancylostoma doudenale occurs in parts of Europe, North Africa, the Middle East, and Asia.
Hookworm infection symptoms may include abdominal pain, diarrhea, loss of appetite, weight loss, fatigue, and the tell-tale sign of anemia. Global estimates suggest that a significant portion of the population is affected by hookworm, which comprises a substantial public health concern, especially in temperate regions where sanitation and hygiene may be compromised.
Hookworm infections, specifically Ancylostoma duodenale and Necator americanus, are associated with iron deficiency anemia. These two species of hookworms can cause abdominal pain, diarrhea, loss of appetite, weight loss, fatigue, and anemia.
The larvae of the hookworms penetrate the skin from soil contaminated by feces and travel to the lungs, eventually maturing in the intestines. Hookworm infections are prevalent in the Americas, Africa, and Asia.
