Diseases

Step 1: Understanding the organisms and their associated diseases

• Haemophilus influenzae: A bacterium that causes pneumonia.
• Entamoeba histolytica: A protozoan parasite responsible for causing amoebiasis.
• Plasmodium falciparum: A protozoan parasite that causes malignant malaria.
• Wuchereria bancrofti: A parasitic worm that causes elephantiasis.

Step 2: Matching the columns

• Haemophilus influenzae → Pneumonia (r)
• Entamoeba histolytica → Amoebiasis (s)
• Plasmodium falciparum → Malignant malaria (p)
• Wuchereria bancrofti → Elephantiasis (q)

The correct answer is (C) : 1-r, 2-s, 3-p, 4-q.

• Haemozoin is a toxic substance released during the breakdown of hemoglobin by the Plasmodium parasite, which causes malaria. This substance is responsible for the high fever and chills associated with malaria.
• In malaria, when the Plasmodium parasite infects red blood cells, it feeds on hemoglobin and releases haemozoin as a byproduct. This release causes an immune response that results in the fever and chills characteristic of the disease.
• Typhoid (Option A), dengue (Option B), and pneumonia (Option C) do not involve the production of haemozoin.

The correct answer is (D) : Malaria.

• Pneumonia typically presents with respiratory symptoms such as difficulty breathing, fever, chills, and cough. A headache may also accompany these symptoms.
• Other options like high fever with stomach pain (Option A), nasal congestion (Option C), and abdominal issues (Option D) are not typical symptoms of pneumonia.

The correct answer is (B) : Difficulty in breathing , fever , chills, cough, headache.
