The ZIEHL NEELSEN Kit is an essential product for staining acid-fast bacteria, fundamental for the diagnosis of mycobacterial infections. This kit is designed for use in microbiology laboratories and for healthcare professionals who need to perform microscopic examinations on pathological samples or culture media. The ZIEHL NEELSEN stain is a proven and highly effective method for identifying mycobacteria, such as those responsible for tuberculosis.

Kit Contents

Each package of the ZIEHL NEELSEN Kit includes:

• 1 250 ml bottle of Fuchsin Solution


• 1 250 ml bottle of Acid-Alcohol Solution


• 1 250 ml bottle of Methylene Blue Solution

Method Principle

The ZIEHL NEELSEN stain is based on the ability of phenol to facilitate the penetration of basic fuchsin into bacterial cells. This process makes it possible to distinguish between acid-fast bacteria and bacteria sensitive to decolorization.

After staining with fuchsin, acid-fast bacteria remain red even after treatment with the Acid-Alcohol Solution, while sensitive bacteria lose the red color and turn blue thanks to the action of Methylene Blue.
