morphology (shape‚ size‚ and arrangement). Stains are solutions that contain a solute called a chromophore dissolved in a solvent. A chromophore is the color possessing portion of the solution and is therefore responsible for the stains color. Bacterial cells usually have a negative surface charge‚ meaning that a positively charged stain is needed to stain the surface of the cell. Most stains are basic and have a positively charged chromophore. When the stain is applied‚ there is an attraction between

Introduction The acid-fast stain was developed in 1882 by Paul Ehrlich. Ehrlich was working with Mycobacterium tuberculosis‚ the bacilli responsible for tuberculosis‚ and found a technique that renders M. tuberculosis distinguishable from nearly all other bacteria. Acid-fast staining is‚ therefore‚ known as a differential stain. Mycobacterium and some Nocardia species are considered acid fast because‚ during the acid-fast procedure‚ they are able to retain the primary dye even when decolorized
