Zn stains (Ziehl–Neelsen stains) and Gram stains are both classic microbiological staining techniques, but they serve different purposes and identify very different groups of bacteria.

1. Gram Stain
Purpose:
To differentiate bacteria into Gram-positive and Gram-negative groups based on the structure of their cell wall.

2. Ziehl–Neelsen (ZN) Stain / Acid-Fast Stain
Purpose:
To identify acid-fast bacteria (AFB), mainly Mycobacterium species (e.g., Mycobacterium tuberculosis).
