Differential stains are used to differentiate between different types of microorganisms based on their cellular properties. Gram stain and Acid-fast stain are both differential stains because they differentiate between different types of bacterial cell walls. Acid-fast stain is used to differentiate acid-fast bacteria (such as Mycobacterium) from non-acid-fast bacteria, while Gram stain is used to differentiate between Gram-positive and Gram-negative bacteria. Flagella stain and capsule stain are not differential stains since they do not differentiate between different types of microorganisms based on their cellular properties.
