Zusammenfassung: | Salmonellais one of the main etiological agents of infectious diarrhea in large and small ruminants but emergence of multidrug-resistant (MDR) strains faster rate than previously, leads to develop of MDR strains among animals needs different alternative therapeutic strategies. Our study was aimed to evaluate the effects of Nigella sativa silver nanoparticles (NS AgNPs) on specific pathogen-free (SPF) Wister rats. Nigella sativa silver nanoparticles were prepared and confirmed their formation by optical observations, UV–Vis spectroscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM). Rats in group G2 were infected experimentally with Salmonella spp and treated with ciprofloxacin orally for duration of 6 days at a dose rat 10 mg/kg. On the other hand, rats in group G1 were infected with salmonella and treated for 20 days with NS AgNPs in oral dose of (10 mg/kg rats), and the results were compared to control groups G3 which received bacterial infection without treatment and G4 control negative. The results of optical observation, UV–Vis spectroscopy, TEM, and SEM revealed typical characteristics of prepared NS AgNPs. Liver, kidney function biomarkers, hematologic analysis, and histological examination the tissues of liver, kidney, and stomach of rat's model improved that NS AgNPs has antimicrobial effect and has the ability to decrease the inflammatory reaction caused by Salmonella spp infection. The results of our study indicate that NS AgNPs are effective in controlling MDR Salmonella spp in vivo without causing any adverse effects. Moreover, our findings suggest that reducing the use of antimicrobials could be a key factor in the fight against antimicrobial resistance and can provide valuable insights into identifying the most appropriate treatment strategies to tackle this issue effectively in the future.
•Multidrug-resistant bacteria create a challenging situation for society to treat infections.•Salmonella spp., the host-adapted serotype in cattle, has the ability to establish lifelong infection.•Plant-based nanoparticles could be an alternative solution as potential drug candidates against these MDR bacteria.•The synthesized AgNPs were characterized and further tested for their antibacterial effacacy, and cytotoxicity properties.•Synthesized AgNPs could be an effective drug against multidrug-resistant salmonella spp. |
