Differential Staining. Gram stain technique is a differential staining technique, which separates bacteria into two groups (discussed in earlier chapters), Gram-positive bacteria and Gram-negative bacteria. Another differential staining technique is acid-fast technique which differentiates species of Mycobacterium from other bacteria.
The differential response to the Gram stain is based on fundamental differences in the. cell wall structure and composition of cells. In a manner quite similar to the Gram stain, the acid-. fast stain differentiates an important group of bacteria, the mycobacteria, on the basis of lipid. content of their cell wall.
