The Gram stain is a simple test that colours bacteria purple or pink, telling us if they have a thick peptidoglycan wall. That split guides our first guess for antibiotics while the lab does the full culture. But you know, in my village, we don't wait for tests if a wound is angry; we clean it with what we have. Studying this, I keep thinking of my porch shutters—the salt eats the good paint first, same as how the pink bacteria are the ones that break through faster and make you sicker.
