Background: Incoherent use of antibiotics has led toward resistance in MRSA, which is becoming multidrugresistant with high rate of virulence in the community and hospital settings. Objective: Synergistic anti-MRSA activity was investigated in this study for hybrid material composite spheres of amoxicillin, Ag nanoparticles and chitosan which were prepared by one-step synthesis method and various characterizations were performed. Methods: Antimicrobial-susceptibility assay on MRSA was achieved by disc diffusion and agar dilution techniques while agar well diffusion was used for hybrid composite spheres. The in vitro and cytotoxicity studies was done by skin abrasion mouse model and MTT assay on RD cell respectively. Results: All isolates were resistant with the tested antibiotics except vancomycin. MIC against MRSA showed high resistance with amoxicillin from 4 to 128 mg L-1. The mean diameter of chitosan spheres and Ag nanoparticles was 02 mm and 277 nm respectively. Morphology of spheres was uneven, varied, porous and irregular in SEM and Ag nanoparticles presence and formation was also seen in micrograph. No substantial interface among drug, nanoparticles and polymer was found in XRD and IR showed characteristic peaks of all compound in the formulation. The in vitro assay showed augmented anti-MRSA activity with amoxicillin loaded hybrid composite spheres (22-29 mm). A significant reduction in microbial burden (~6.5 log10 CFU ml-1) was seen in vivo with loaded hybrid composite spheres formulation. The MTT assay indicated no potential cytotoxicity with hybrid composite spheres. Conclusion: Synergistic effect, amoxicillin, new hybrid formulation, anti-MRSA activity, composite spheres. nanoparticles.
