Representative photos of blood film for one representative rat blood film of (A) Group I (negative control, shaved animal skin was not swapped with S. aureus, with no samples swapping), (B) Group II (positive control, animal skin was swapped only with S. aureus, and remained untreated), (C) Group III (shaved animal skin was swapped with S. aureus followed by swapping with ZnO-NPs group), (D) Group IV (shaved skin was swapped with S. aureus and then swapped with 3% PVP), and (E) Group V, (shaved animal skin was swapped with bacteria and then after swapped with Sterillium), all groups revealed no abnormalities or alteration in shape of RBCs when compared to negative control and this is indicative of absence of any harmful effect for both ZnO-NPs and Sterillium.
