বিবরন:Enhancement of antivenom immune responses in horses through adjuvant technology improves antivenom production efficiency, but substantial local reactogenicity associated with some traditional veterinary adjuvants limits their usability. To explore modern adjuvant systems suitable for generating antivenom responses in horses, we first assessed their physicochemical compatibility with Bothrops asper snake venom. Liposome and nanoparticle aluminum adjuvants exhibited changes in particle size and phospholipid content after mixing with venom, whereas squalene emulsion-based adjuvants remained stable. Next, we evaluated serum antibody response magnitude and neutralization capacity in horses immunized with adjuvant-containing Echis ocellatus, Bitis arietans, Naja nigricollis, and Dendroaspis polylepis venom preparations. Whereas all tested adjuvants elicited significant neutralization capacity against the viperid venoms, the greatest antibody responses were generated by a squalene-in-water emulsion, thus representing a promising novel alternative for antivenom production.
