It involves staining an organism with crystal violet or methylene blue dye and then observing the organism under a microscope. Gram-positive bacteria have a thick peptidoglycan cell wall.

As the bacteria grow, they spit out peptidoglycan, a component of the cell wall that acts like a large molecular bag. These remnants can still cause inflammation if injected into healthy mice.
