Question:
Acid fast staining method includes which of the following
Acid fast staining method includes which of the following
Show Hint
Carbol fuchsin is key in differentiating acid-fast bacteria from non-acid-fast bacteria. The red color produced is resistant to decolorization by acid-alcohol.
Updated On: May 5, 2025
- Methyl red
- Safranine
- Crystal violet
- Carbol fuchsin
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In the acid-fast staining method, carbol fuchsin is used as the primary stain. It binds strongly to the cell wall of acid-fast bacteria, such as Mycobacterium species, allowing them to retain the red color after washing.
