  • gram positive are those bacteria which remain coloured blue or purple gram staining even after washing with alcohol. gram negative are those bacteria that do not retain the stain when washed with alcohol and murein content is 10 -20 %and teichoic acid is absent In cell wall.

  • 1. Gram-positive bacteria have multilayered cell walls while gram-negative bacteria have single layered walls.
    2. Gram-positive bacteria gives purple color in a crystal violet dye while gram-negative bacteria don't react with crystal violet dye and also go reverse thus giving pinkish colored stain.
    3. Gram-negative bacteria are penicillin resistant whereas gram-positive bacteria responds to penicillin treatment.
