(Twitter: @DrWhitneyHolden) The AcidFast stain is an important differential stain used to distinguish between AcidFast bacteria and NonAcidFast Bacteria, based on the presence or absence of mycolic acid in their cell walls. In this video, Biology Professor will cover the AcidFast stain procedure and discuss how it is applied to determine the presence of Mycobacteria, which include the bacteria that cause tuberculosis and leprosy. Great for MCAT Biology Review! For information on the Gram Stain, another important differential stain, see Biology Professor's video:    • Gram Stain Procedure
