Effect of PG on S. aureus-inoculated wound length. Mice were inoculated with 20 μL of 2.5 × 109 CFU/mL of S. aureus at the sites of skin wound immediately after wounding, and then treated with 10 μL of 10 mg/mL PG daily. On days 2, 4 and 6 after infection, the skin tissues were collected and paraffin sections were prepared. After staining with H&E, the length of infected wound was measured (5 mice per group per each experiment). The pictures of histology are representative (A). The length of infected wound is expressed as the means ± SD of 2 independent experiments (B). An asterisk (p < 0.05) indicates that the value is significantly different from the DW control group.
