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.
By following the Gram stain procedure I will determine which type(s) of bacteria are in the cultures grown in the science lab. Background Information: Differential stains are very useful in microbiology because they can be used to distinguish between groups of bacteria. The Gram stain is one of the most important steps in the characterization and identification of bacteria. The Gram stain separates bacteria into one of two groups: 1) Gram-positive bacteria. These retain the color of the first stain used (Crystal Violet).
