Here we see Mycobacterium tuberculosis in a sputum smear is stained using fluorescent acid-fast stain, 1971. M. tuberculosis is an acid-fast bacterium (AFB), and is therefore, undetectable when stained using a Gram stain technique. However, using this method, the M. tuberculosis bacteria glow yellow under ultraviolet light microscopy. Image courtesy CDC/Ronald W. Smithwick.

RMKR15J1–Here Mycobacterium tuberculosis in a sputum smear is stained using the Ziehl-Neelsen technique, Magnified 1000x, 1971. Ziehl-Neelsen technique is used for staining acid-fast bacteria using a carbol-fuchsin solution, decolorizing in acid alcohol, and counterstaining with methylene blue. Mycobacteria, have waxy coated cell walls which prevents Gram staining. Image courtesy CDC/Ronald W. Smithwick.
