Very few structures are acid-fast; this makes staining for acid-fastness particularly useful in diagnosis. The following are notable examples of structures which are acid-fast or modified acid-fast: All Mycobacteria – M. tuberculosis, M. leprae, M. smegmatis and atypical mycobacteria.
Mechanism of acid-fast staining in acid-fast cells and non-acid-fast cell [24] [25] [26] The mechanism of action of the Ziehl-Neelsen stain is not completely understood, but it is thought to involve a chemical reaction between the acidic dyes and the cell walls of the bacteria .

The Kinyoun method can be modified as a weak acid fast stain, which uses 0.5–1.0% sulfuric acid instead of hydrochloric acid.The weak acid fast stain, in addition to staining Mycobacteria, will also stain organisms that are not able to maintain the carbol fuchsin after decolorizing with HCl, such as Nocardia species and Cryptosporidium.
In solution with phenol (also called carbolic acid) as an accentuator [17] it is called carbol fuchsin and is used for the Ziehl–Neelsen and other similar acid-fast staining of the mycobacteria which cause tuberculosis, leprosy etc. [18] Basic fuchsine is widely used in biology to stain the nucleus, and is also a component of Lactofuchsin ...
Franz Ziehl introduced the carbol fuchsin stain for the tubercle bacillus in 1882. With pathologist Friedrich Neelsen (1854–1898), he developed the Ziehl–Neelsen stain , [ 1 ] also known as the acid-fast stain, which is used to identify acid-fast bacteria .
