Number of acid fast organisms

How many acid fast organisms are there?

Not known

It is impossible to provide an exact answer to this question.  The main idea is that acid-fast organisms are difficult to characterize using standard microbiological techniques.  Keep in mind the fact that acid-fastness is a physical property of certain bacteria to resist to decolorization by acids during staining procedures.  Not too many people know the fact that acid-fast bacteria can be visualized by fluorescence microscopy using specific fluorescent dyes.  It is interesting to know that the most popular technique used to identify acid-fast bacteria is the Ziehl-Neelsen stain.
