Histopathologic examination of burn wound infection. Cross-sectional biopsy samples were collected on Days 4, 7, and 14 from A. baumannii and K. pneumoniae-infected rat burn wounds; then, H&E staining was conducted. Treatment with PdB accelerated the wound healing process. A There is no significant difference in the re-epithelialization rate of the PdB-treated and control groups on Day 4. This treatment increased re-epithelization remarkably in the treated animal compared to the control groups on Days 7 and 14. B wide granulation tissue was observed in PdB-treated animals in comparison to that in the control groups. Data are presented as mean ± SEM. *P value < 0.05, ***P value < 0.001
