Ziehl–Neelsen staining is a type of narrow spectrum fungal stain. Narrow spectrum fungal stains are selective, and they can help differentiate and identify fungi. [ 10 ] The results of Ziehl–Neelsen staining is variable because many fungal cell walls are not acid fast. [ 11 ]
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 .
A Ziehl–Neelsen stain is an acid-fast stain used to stain species of Mycobacterium tuberculosis that do not stain with the standard laboratory staining procedures such as Gram staining. This stain is performed through the use of both red coloured carbol fuchsin that stains the bacteria and a counter stain such as methylene blue.
Ziehl–Neelsen stain (classic and modified bleach types) [5]; Kinyoun stain; For color blind people (or in backgrounds where detecting red bacteria is difficult), Victoria blue can be substituted for carbol fuchsin and picric acid can be used as the counter stain instead of methylene blue, and the rest of the Kinyoun technique can be used.
It is Gram-positive by Gram staining, but Mycobacterium leprae was traditionally stained with carbol fuchsin in the Ziehl–Neelsen stain. Because the bacilli are less acid-fast than Mycobacterium tuberculosis (MTB), the Fite-Faraco staining method, which has a lower acid concentration, is used now. [9] [10] In size and shape, it closely ...

Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium.It is 3.0 to 5.0 μm long with a bacillus shape and can be stained by Ziehl–Neelsen method and the auramine-rhodamine fluorescent method.
