I also have videos on the AcidFast Stain, Flagella Stain, Endospore Stain, Capsule Stain and more if you want to check them out! Here is a link to a playlist on all my videos relating to Microbiology Stains:

LEARN ABOUT THE CHARACTERISTICS OF GRAMPOSITIVE AND GRAMNEGATIVE CELL WALLS HERE:    • Gram Positive and Gram Negative Bacteria  

Gram staining is possibly the single most important differential stain used to distinguish between different types of bacteria based on their chemical and physical properties. In this video, Biology Professor (Twitter: @DrWhitneyHolden) will cover the Gram stain procedure and discuss how it is applied to determine what type of bacterium is causing a given disease. Great for MCAT Biology Review! For more information on the structural differences between GramPositive and GramNegative Cell Walls, see Biology Professor's video:    • Gram Positive and Gram Negative Bacteria   For more information on another type of differential stain, the AcidFast stain, see Biology Professor's video:    • AcidFast Stain
