The Acid-Fast Stain is important because it is a differential stain that is helpful in diagnosing tuberculosis. It is a simple stain that differentiates Mycobacterium species from other bacteria. More than one of the choices can be true. It is an acid (negatively charged) dye that stains cell walls of most eubacteria.
