Cite the purpose of following reagents in a differential staining procedure?
To distinguish between acid fast positive and acid fast negative bacteria. Acid fast positive bacteria will stain red to pink color and acid fast negative bacteria will stain blue. Acid fast positive bacteria have mycolic acid in their cell wall, which will stain with carbol fuchsin and not decolorize with acid alcohol. Acid fast negative bacteria do not have mycolic acid in their cell wall, and become decolorize with the acid alcohol. Counterstain of methylene blue needs to be done in order to see the acid fast negative.
Why is that the microorganisms in the hay infusion are not stained?
Microorganisms in the hay infusion are not stained because the microorganisms are gram negative and if we are trying to use stain them, only gram positive organisms can pick up.
