GRAM POSITIVE AND GRAM NEGATIVE
Gram-negative bacteria are bacteria that do not retain crytal violet dye in the Gram staining protocol. In a Gram stain test, a counterstain (commonly safranin) is added after the crystal violet, coloring all Gram-negative bacteria with a red or pink color.
On the other hand, Gram positive bacteria will retain the crystal violet dye when washed in a decolorizing solution.
