WebFigure 2.33 Gram-staining is a differential staining technique that uses a primary stain and a secondary counterstain to distinguish between gram-positive and gram-negative bacteria. The purple, crystal-violet stained cells are referred to as gram-positive cells, while the red, safranin-dyed cells are gram-negative ( Figure 2.34 ). WebThese bacteria with a thin cell wall are counterstained with safranin and are labeled as the Gram-negative bacteria.
