As a modifier (also in the genitive). Designating a method of staining used to identify and classify bacteria and certain other microorganisms, esp. in Gram stain.The technique of Gram staining involves several steps: an initial staining with a purple dye (gentian violet), fixation of the colour with an iodine solution, washing with alcohol or acetone, and a final staining with a red dye. Some microorganisms retain the purple dye and are known as Gram-positive; Gram-negative organisms lose the purple colour and are stained by the red dye. These staining properties are determined mainly by the structure and peptidoglycan content of the microorganism's cell wall, and correlate with the response of the microorganism to certain types of antibiotic.
