Antiseptics are essential in infection control within veterinary medicine and are widely used for wound care, dermatological treatments, and disinfection. Growing interest in eco-friendly antiseptics has led to research on natural formulations. The aim of this study is to evaluate the efficacy and safety of natural antiseptic agents in combating pathogenic microorganisms and their use in disinfection. This article presents the results of efficacy testing, particularly focusing on Shozan (anolyte + ozone + shungite), which demonstrated strong bactericidal activity against pathogenic bacteria such as Brucella melitensis, effectively inhibiting their growth across various concentrations and exposure times. In contrast, Shuprozan (anolyte + ozone + shungite + propolis) and Prozan (anolyte + ozone + propolis) did not exhibit significant antibacterial effects. No antiviral activity was detected against the lumpy skin disease virus and foot-and-mouth disease virus, and no fungicidal properties were observed against Trichophyton verrucosum and Histoplasma farciminosum. This study’s results confirm the high efficacy and safety of natural antiseptics.
