Effective Foot‐and‐Mouth Disease Virus Control Using Silver Nanoparticles.

This study investigates the antiviral efficacy of chitosan‐stabilized silver nanoparticles (AgNPs) against the Foot‐and‐Mouth Disease virus (FMDV), a highly contagious pathogen affecting cloven‐hoofed animals. In vitro experiments demonstrated that AgNPs effectively inhibited FMDV replication in a dose‐dependent manner. At a concentration of 1.56 μg/ml, AgNPs exhibited no cytotoxicity to baby hamster kidney 21 (BHK21) cells while achieving complete deactivation of FMDV at a titer of 103 TCID50 and inhibiting viral growth at a titer of 104 TCID50. These findings suggest the potential of silver nanoparticles as a novel disinfectant for controlling FMDV transmission and preventing disease outbreaks. [ABSTRACT FROM AUTHOR]
