Staphylococcus has

Options

A. Cubical colony
B. Bunch -like irregular colony
C. Chain like colony
D. Plate like colony.

Answer

**Step-by-Step Solution:**

1. **Understanding Bacterial Colonies**: Begin by recognizing that bacteria can form different types of colonies based on their arrangement. Common arrangements include single cells, pairs, chains, and clusters.

2. **Identifying Staphylococcus**: Staphylococcus is a genus of bacteria that is characterized by its arrangement. It is known for forming clusters that resemble a bunch of grapes.

3. **Comparing Colony Types**:
- **Coccus**: Refers to single spherical bacteria.
- **Diplococcus**: Refers to two spherical bacteria together.
- **Streptococcus**: Refers to bacteria that form chains.
- **Tetrad**: Refers to four bacteria grouped together.
- **Sarcina**: Refers to cubical arrangements of bacteria.
- **Staphylococcus**: Refers to irregular clusters or bunches of spherical bacteria.

4. **Evaluating the Options**:
- **Cubical Colony**: Incorrect, as this describes Sarcina.
- **Bunch-like Irregular Colony**: Correct, as this describes Staphylococcus.
- **Chain-like Colony**: Incorrect, as this describes Streptococcus.
- **Plate-like Colony**: Incorrect, as this does not apply to Staphylococcus.

5. **Conclusion**: The correct answer is that Staphylococcus has a bunch-like irregular colony.

**Final Answer**: Staphylococcus has a bunch-like irregular colony.
