Key Concept
Gram Stain Characteristics
Explanation
Mycobacterium tuberculosis does not stain as a red rod in Gram stain. Instead, it is known for its acid-fast properties due to the presence of mycolic acid in its cell wall, which makes it resistant to Gram staining. In Gram staining, it typically appears as weakly Gram-positive or Gram-variable.
