Nov 11, 2024 · Acid-Fast Stain- Principle, Procedure, Interpretation and Examples. It is the differential staining techniques which was first developed by Ziehl and later on modified by Neelsen.

The most common staining technique used to identify acid-fast bacteria is the Ziehl–Neelsen stain, in which acid-fast species appear bright red against a blue background.

The acid-fast stain is performed on samples to demonstrate the characteristic of acid fastness in certain bacteria and the cysts of Cryptosporidium and Isospora.

Acid fast stain is a differential stain used to identify acid-fast organisms such as members of the genus Mycobacterium. Acid-fast microorganisms are characterized by wax-like, nearly impermeable cell …
