This investigation was carried out to estimate the antiparasitic potential of silver and Chitosan nanoparticles loaded with spiramycin against toxoplasmosis infected. After mice injected intraperitoneal in a dose 10 3 viable tachyzoites for acute infection; then treated with spiramycin, chitosan nanoparticles and silver nanoparticles as a single or combined therapy given for seven days. Peritoneal fluid examination revealed a significant decrease in the number of T. gondii tachyzoites in all treated infected mice compared with infected non-treated. The combined therapy presented better results than the single one. The best effect was observed in a group of mice treated with the combined chitosan nanoparticles and silver nanoparticles loaded with spiramycin. Also, immunological parameters IgM antibody, INF-γ and TNF-α cytokines responses against T. gondii antigens were assessed in serum samples by enzyme-linked immunosorbent assays (ELISA) kits after treatment. The current work is the first time of using Ag NPs and CS NPs loaded with spiramycin as therapeutic agents against experimental toxoplasmosis. It was shown that the highest degree of effectiveness attained by the synergistic action of chitosan and Ag NPs as was indicated by lower parasite count and IFN-γ, TNF-α concentration.
