Bacteria producing T. B .and Leprosy (Mycobacterium species) belong to

Options

A. Archaebacteria
B. Actinomycetes
C. Eubacteria
D. Rickettsiae.

Answer

To determine the classification of bacteria that cause tuberculosis (TB) and leprosy, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Bacteria**:
- Tuberculosis is caused by *Mycobacterium tuberculosis*.
- Leprosy is caused by *Mycobacterium leprae*.

2. **Understand the Classification Options**:
- The options given are:
- a) RT bacteria
- b) Actinomycetes
- c) Eubacteria
- d) Trichocereus

3. **Analyze the Characteristics of Mycobacterium**:
- Both *Mycobacterium tuberculosis* and *Mycobacterium leprae* are classified as bacteria.
- They are filamentous and gram-positive, which means they have a thick cell wall that retains the crystal violet stain used in the Gram staining procedure.

4. **Determine the Correct Group**:
- Actinomycetes are a group of bacteria that are filamentous, gram-positive, and share characteristics with fungi.
- Given that *Mycobacterium* species are filamentous and gram-positive, they fit the description of actinomycetes.

5. **Select the Correct Answer**:
- Based on the analysis, the correct classification for the bacteria causing TB and leprosy is **Actinomycetes**.

### Final Answer:
Bacteria producing TB and leprosy (Mycobacterium species) belong to **Actinomycetes**.
