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.
Test your knowledge about Mycobacteria and their unique characteristic of retaining the carbol fuchsin stain after treatment with an ethanol-hydrochloric acid mixture, due to their high lipid content in the cell wall.
