... Acid fast microbes are pathogenic for humans, therefore observing them is critical. The diagnostic value of acid-fast stain is that pathogens retain color even in presence of acid. For example tuberculosis would retain the red dye carbolfuchsin even after it was washed with a powerful solvent made o ...
