Gram stain that shows cocci into the mouse pinna previously infected with S. pyogenes strain B-50879. The images are representative fields at 40x of the tissue from pinna of mice infected or PBS-treated after previous damage and stained with GRAM. The squares were amplified with the immersion oil objective to show a 1000x magnification. a, c and e are tissue infected with S. pyogenes at 48 h, 96 h and 144 h post inoculation. b, d and f are tissue treated with PBS at 48 h, 96 h and 144 h respectively
