چکیده انگلیسی


• Infection of vancomycin sensitive and resistant strain of Staphylococcus aureus in murine peritoneal macrophage.
• S. aureus infection-induced oxidative stress in murine peritoneal macrophages.
• In vitro ameliorative role of nanoconjugated vancomycin (NV) against S. aureus infection-induced oxidative stress in murine peritoneal macrophages.

AimsThe present study was aimed to evaluate the in vitro ameliorative effect of nanoconjugated vancomycin (NV) against vancomycin sensitive and resistant strains of Staphylococcus aureus infection-induced oxidative stress in murine peritoneal macrophage.MethodsPeritoneal macrophages from mice were treated with VSSA and VRSA (5 × 106 CFU/mL), VSSA + NV (5–250 μg/ml) and VRSA + NV (5–250 μg/ml) for 18 h, having 3 h interval in culture media; and the superoxide anion generation, lipid peroxidation, protein oxidation, antioxidant enzymes status and glutathione enzymes activity were monitored.ResultsThe significantly increased free radical generation, lipid peroxidation, protein carbonyls and oxidized glutathione levels were observed in VSSA and VRSA treated group as compared to control group; where as reduced glutathione level, antioxidant enzymes status and glutathione dependent enzymes were decreased significantly. All these changes come near to control in NV treated group in a dose and duration dependent fashion. Among the different doses and duration intervals of NV, maximum ameliorative effect was observed by 100 μg/ml for 12 h treatment which does not produce any damage to the cell.ConclusionsThese findings suggest the potential use and beneficial role of nanoconjugated vancomycin as a modulator of S. aureus infection-induced cellular damage in murine peritoneal macrophage.
