Acid-fast staining is based upon the principle of staining the bacterial cell relative to their cell wall differences. The cells of Mycobacteria species appear red whereas non-acid fast bacteria appear blue. A smear is subjected to heat after staining with Zeihl Neelson Carbol fuschin. During steam carbol fuschin penetrates the bacterial cell. Acid-fast stain After staining with basic fuchsin acid-fast bacteria resist decolonization by acid-alcohol. Non-acid-fast bacteria are counterstained with methylene blue. Used to distinguish acid-fast bacteria such as M. tuberculosis from non-acid-fast cells.

Acid-fast results
Purpose To differentiate between acid-fast and non acid-fast bacteria. Principle Some bacteria contain a waxy lipid mycolic acid in there cell wall. This lipid makes the cells more durable and is commonly associated with pathogens. Acid fast cell walls are so durable that the stain (carbol fuschin) must be driven into the cells with heat. Jun 12 2018 · The non-acid fast organism lack the lipoidal material in their cell wall due to which they are easily decolorized leaving the cells colorless. Then the smear is stained with counterstain methylene blue. Only decolorized cells absorb the counter stain and take its color and appears blue while acid-fast cells retain the red color.
