Abstract: | The aims of this study were to determine the main bacteria species that caused wound infections and to investigate the antibacterial effects of ZnO-NPs against them. Samples were taken from 37 goat wounds. Then wound samples were diagnosed using morphological examination, gram stain examination, and biochemical analysis. Results showed that 21 (56.76%) of the cases were positive, and 16 (43.24%) were negative for bacteria isolation. The main species of bacteria isolated most commonly were Staphylococcus aureus (66.67%), Pseudomonas aeruginosa (23.8%), and Escherichia coli (9.5%). ZnO nanoparticles were tested for antibacterial activity using well diffusion assays at different concentrations (16, 8, 4, and 2 mg/ml). In sensitivity testing of isolates to different concentrations of ZnO NPs, the highest area of inhibition was found in S. aureus (19.67±5.50) mm as compared to P. aeruginosa (22.00±5.29) mm and E. coli (20.67±4.61) mm Mean ±SE. In conclusion, in vitro testing of zinc oxide nanoparticles against bacteria showed that when used at different concentrations, they inhibited bacterial growth at different rates. |
