Gram-Negative Bacterial Infection in Thigh Abscess Can Migrate to Distant Burn Depending on Burn Depth

Figure 5

Effect of varying burn depth on infection by P. mirabilis. Mice were subjected to 1-second (superficial), 3-second (partial thickness), 6-second (full thickness), or 9-second (full thickness with underlying muscle damage) exposure to the 90°C water, followed by injection of bioluminescent P. mirabilis in the thigh and imaged 24 hrs later. The scale of pseudocolor indicates the intensity of the bioluminescence, with the higher numbers and pink color corresponding to the highest level of bioluminescence and the lowest numbers and purple color corresponding to the lowest level of bioluminescence.
