PHIL Image 13371
 
ID#:13371
Description:This fluorescent acid-fast stained (Smithwick) photomicrograph revealed the presence of Mycobacterium tuberculosis bacteria in a sputum smear.

M. tuberculosis is an acid-fast bacterium (AFB), and is therefore, undetectable when stained using a Gram-stain technique. However, using the Smithwick method, which employs acridine orange as the specific stain, the M. tuberculosis bacteria glow yellow under ultraviolet light microscopy.
