In Vivo Imaging and Histological Analysis at 2 weeks after surgery. A X-ray images of rat femurs, with the red arrow indicating the bone defect; B Imaging scores (including architectural deformation (AD), periosteal elevation (PE), widening of the bone shaft (WBS), new bone formation (NBF), and total score) of the control, E. coli, and PVA + E. coli groups; C Imaging scores (including architectural deformation (AD), periosteal elevation (PE), widening of the bone shaft (WBS), new bone formation (NBF), and total score) of the control S. aureus and PVA + S. aureus groups; D H-E staining of rat femurs, with the black dotted line representing the purulent lesion, and NB indicating new bone formation; bar = 200 μm. E Histological scores of the bacterial and PVA + bacterial groups. Data are presented as means ± SD. Significant differences are indicated as **(p < 0.05)
