1. 2 dyes are applied to bacteria
a. violet stain- primary stain
b. Red stain- counter stain
2. Violet stain is applied first stains peptidoglycan cell wall
3. Alcohol is applied and if bacteria stays violet it is gram-postive
4. If bacteria are Gram-Negative they will have thin walls and an outer lipid layer. Alchohol dissolves lipids and counter stian dyes them red/pink |
