AFB Stain

 

 

 

 

 

Intended use
  This stain is used to differentiate the genus Mycobacterium from most other bacteria.

 

Background
  Acid-fast cells (Acid Fast Bacilli) contain mycolic acid, a waxy material, in the cell walls. The Ziehl-Neelsen (ZN) method uses a primary stain of the lipid (fat) soluble carbolfuchsin, with steam heat acting as mordant to drive the stain into the cell. These cells resist decolorizing by acid alcohol. Nonacidfast cells will be decolorized. A counterstain of methylene blue will stain these decolorized cells. Acid-fast cells stain a red or pink, non-acid-fast cells stain blue.
