Putrefying bacteria are found in
(a) Intestine
(b) Stomach
(c) Liver
(d) Colon

Options

A. Intestine
B. Stomach
C. Liver
D. Colon

Answer

To determine where putrefying bacteria are found in the human body, we need to analyze the options provided:

1. **Understanding Putrefying Bacteria**:
- Putrefying bacteria are involved in the process of putrefaction, which is the decomposition of proteins. This process is primarily carried out by certain bacteria and fungi.

2. **Analyzing the Options**:
- **(a) Intestine**: While the intestine does contain bacteria, it is not the primary site for putrefying bacteria.
- **(b) Stomach**: The stomach has a highly acidic environment (due to gastric acid), which is not conducive to the survival of putrefying bacteria.
- **(c) Liver**: The liver is involved in metabolism and detoxification but does not host putrefying bacteria.
- **(d) Colon**: The colon is known for its diverse microbiota, including putrefying bacteria. These bacteria play a role in the fermentation of undigested food and the production of certain vitamins.

3. **Conclusion**:
- Based on the analysis, putrefying bacteria are primarily found in the colon. They help in the decomposition of organic matter and contribute to the production of vitamins like B12.

Thus, the correct answer is **(d) Colon**.
