Question

Match List I with List II

List I		List II
A	Typhoid	I	Fungus
B	Leishmaniasis	II	Nematode
C	Ringworm	III	Protozoa
D	Filariasis	IV	Bacteria

Choose the correct answer from the options given below:

• A. A-I, B-III, C-II, D-IV
• B. A-IV, B-III, C-I, D-II
• C. A-III, B-I, C-IV, D-II
• D. A-II, B-IV, C-III, D-I

Answer 1

The Correct Option is B

To match the items from List I with their corresponding agents from List II, consider the following explanations for each disease:

• Typhoid is caused by bacteria. Specifically, the bacterium Salmonella typhi is responsible for this disease. Hence, Typhoid corresponds to option IV.
• Leishmaniasis is caused by a protozoan parasite, typically of the genus Leishmania. Therefore, it matches with option III.
• Ringworm is a skin disease caused by a fungus. Various species of dermatophytes, which are fungi, are responsible. Thus, Ringworm aligns with option I.
• Filariasis is caused by a nematode or roundworm, such as Wuchereria bancrofti. So, Filariasis relates to option II.

Based on these associations, the correct matching of List I with List II is:

• A-IV: Typhoid - Bacteria
• B-III: Leishmaniasis - Protozoa
• C-I: Ringworm - Fungus
• D-II: Filariasis - Nematode

Therefore, the correct answer is: A-IV, B-III, C-I, D-II.

Answer 2

Step 1: Understanding the causes of each disease:

A. Typhoid: Typhoid fever is an infectious disease caused by the bacterium Salmonella typhi. It is transmitted through contaminated food and water, often leading to symptoms such as fever, weakness, abdominal pain, and diarrhea. The causative agent of Typhoid is IV. Bacteria.

B. Leishmaniasis: Leishmaniasis is caused by a group of protozoan parasites of the genus Leishmania. These parasites are transmitted by the bite of infected sandflies. Leishmaniasis can cause skin ulcers, swelling, and in severe cases, damage to internal organs like the liver and spleen. The causative agent is a III. Protozoa.

C. Ringworm: Ringworm is a fungal infection that affects the skin, hair, or nails. It is caused by various types of fungi, including species from the genera Trichophyton, Microsporum, and Epidermophyton. Ringworm is contagious and can be transmitted through direct skin contact or contaminated objects. The causative agent is a I. Fungus.

D. Filariasis: Filariasis is a parasitic disease caused by nematode worms, specifically Wuchereria bancrofti, Brugia malayi, and Brugia timori. The disease is transmitted to humans through the bite of infected mosquitoes. It causes severe swelling, particularly in the legs, leading to the condition known as elephantiasis. The causative agent is a II. Nematode.

Step 2: Conclusion:

The diseases and their respective causes are matched as follows:

• A - IV: Typhoid is caused by a bacterium, Salmonella typhi.
• B - III: Leishmaniasis is caused by a protozoan parasite, Leishmania.
• C - I: Ringworm is caused by fungi like Trichophyton.
• D - II: Filariasis is caused by nematodes, specifically Wuchereria bancrofti.

Answer: The correct answer is (2) A-IV, B-III, C-I, D-II.
