Einführung
The cell walls of mycobacteria contain a large amount of lipid on the outside of the peptidoglycan, so it is not easy to stain. When the mycobacterium acid of mycobacteria combines with dye, it is difficult to be destained by acid decolorizing solution. This method is called Acid-Fast Bacillus Stain. Traditional dyeing methods need to promote staining by heating and extending the time. The most representative method is the Ziehl-Neelsen method, which is recommended by the WHO and China Tuberculosis Control Program.
Acid-Fast Bacillus AFB ) Färbung Kit ( Auramin -o -Methode ) belongs to the fluorescent staining solution, which needs no heating and is relatively safer than acid-fast hot staining solution. The principle of this method is that after Tauramine o-rhodamine staining and redyeing at room temperature, the acid-fast bacilli show bright yellow, while other bacteria and substances in the background show dark yellow. This method can be used to detect acid-fast bacilli with low magnification.
