Which one of the following diseases cannot be cured by taking antibiotics ?

Options

A. Plague
B. Amoebiasis
C. Leprosy
D. Whooping cough

Explanation

To determine which disease cannot be cured by taking antibiotics, we need to analyze each option provided in the question. Here's a step-by-step solution:

### Step 1: Understand the Role of Antibiotics
Antibiotics are medications specifically designed to treat bacterial infections. They are effective against bacteria but do not work against viral or protozoan infections.

**Hint:** Remember that antibiotics target bacteria, not viruses or protozoa.

### Step 2: Analyze Each Option
1. **Plague**: This is caused by the bacterium *Yersinia pestis*. Antibiotics can effectively treat plague.

**Hint:** Identify if the disease is caused by bacteria.

2. **Amoebiasis**: This disease is caused by the protozoan *Entamoeba histolytica*. Since it is a protozoan infection, antibiotics are not effective against it.

**Hint:** Look for diseases caused by protozoa, as they cannot be treated with antibiotics.

3. **Leprosy**: Caused by the bacterium *Mycobacterium leprae*, leprosy can be treated with antibiotics.

**Hint:** Confirm if the disease is bacterial.

4. **Whooping Cough**: This is caused by the bacterium *Bordetella pertussis*. Antibiotics can treat whooping cough.

**Hint:** Check if the disease is bacterial.

### Step 3: Identify the Correct Answer
From the analysis, we find that:
- Plague, leprosy, and whooping cough are all bacterial diseases and can be treated with antibiotics.
- Amoebiasis is caused by a protozoan and cannot be treated with antibiotics.

Thus, the correct answer is **option 2: Amoebiasis**.

**Final Answer:** Amoebiasis cannot be cured by taking antibiotics.
