The emb dye will enter the gram positive bacteria and inhibit growth, but gram negative bacteria are protected by their enhanced cell wall and will be able to grow on these plates these tubes were developed for clinical use to identify bacteria they contain thirteen compartments, each with a different type of media, which will test for the presence of a different enzyme or set of enzymes in the unknown. Staphylococci are spherical gram-positive cocci arranged in irregular grapelike clusters with type-specific antiserum, capsules swell (quellung reaction), and this can be used to identify the type capsules are virulence factors ie, they interfere with phagocytosis and favor invasiveness in sputum, pneumococci are seen as lancet-shaped gram-positive diplococci in gram-stained smears.
