Streptokinase which is used as a 'clot buster' obtained from

Options

A. Streptococcus
B. Staphylococcus
C. Lactobacillus
D. Saccharomyces

Answer

**Step-by-Step Solution:**

1. **Understanding Streptokinase**: Streptokinase is an enzyme that is used as a 'clot buster' in medical treatments. It helps dissolve blood clots that can cause serious health issues, such as heart attacks.

2. **Source of Streptokinase**: The enzyme is produced by a specific type of bacteria. The question provides four options: Streptococcus, Staphylococcus, Lactobacillus, and Saccharomyces.

3. **Identifying the Correct Bacteria**:
- **Streptococcus**: This is a genus of bacteria known for its hemolytic properties and is the correct source of streptokinase.
- **Staphylococcus**: This is another genus of bacteria, but it does not produce streptokinase.
- **Lactobacillus**: This genus is known for producing lactic acid and is not related to streptokinase production.
- **Saccharomyces**: This is a genus of fungi, primarily yeast, and does not produce streptokinase.

4. **Conclusion**: Based on the above analysis, the correct answer is **Streptococcus**, as it is the bacterium from which streptokinase is obtained.

**Final Answer**: Streptokinase is obtained from **Streptococcus**.
