How would you classify this stain, which is differential for bacteria like Mycobacterium tuberculosis? Acid fast bacilli - Wade Fite stain a. Gram (+) b. Acid fast (-) c. Acid fast (+) d. Spore (-) e. Spore (+) f. Gram (+)
Sri K.
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.

Gram Stain and Acid-Fast Stain. 2. For each of the following steps, indicate what the anticipated color of a Gram-positive or a Gram-negative bacterium would be: Gram stain step Gram-positive bacteria Gram-negative bacteria After crystal violet After Gram's iodine After alcohol After counter-stain (safranin) a. What is the purpose of the iodine? b. Suppose that you are staining an old culture (more than 24 hrs) of Gram-positive organisms. How will the age of the culture affect the staining results? Why?
