Carbol fuchsin is a chemical compound used as a biological stain in microbiology, specifically in the staining of acid-fast bacteria, such as Mycobacterium tuberculosis. It is also known as Ziehl–Neelsen stain or Ziehl–Neelsen carbol fuchsin stain. Carbol fuchsin is a mixture of basic fuchsin, phenol, and water, and it is commonly employed in the Ziehl-Neelsen staining technique to identify acid-fast organisms, which appear red when stained with carbol fuchsin. This staining method is crucial for the diagnosis of tuberculosis and other infections caused by acid-fast bacteria. Carbol fuchsin imparts a strong red color to acid-fast organisms, allowing for their visualization under the microscope.
