Study Notes
Mycobacteria Characteristics
- Mycobacteria are acid-fast, meaning they retain the carbol fuchsin stain after treatment with an ethanol-hydrochloric acid mixture.
- The high lipid content (approximately 60%) of their cell wall is responsible for this acid-fast property.
- Mycobacteria are Gram-positive.
- The lipid content of Mycobacteria's cell wall is approximately 60%, not 40%.
- The carbol fuchsin stain is retained by Mycobacteria due to the high lipid content of their cell wall.
