Bactericidal Efficacy of Vital-Oxide ® , Disinfectant Solution Against Salmonella Typhimurium and Brucella Ovis

Salmonella spp. and Brucella spp. have caused a considerable disease of farmed animals and eco- nomic loss in animal farming and food industry. In this study, the disinfection efficacy of Vital-Oxidel ® , a commercial disinfectant, composed to chlorine dioxide, betaine hydrochloride, and propylene glycol was evaluated against S. typhimurium and Brucella ovis. A bactericidal efficacy test by broth dilution method was used to determine the lowest effective dilution of the disinfectant following exposure to test bacteria for 30 min at 4 o C. Vital-Oixdel ® and test bac- teria were diluted with distilled water (DW), hard water (HW) or organic matter suspension (OM) according to treat- ment condition. On OM condition, the bactericidal activity of Vital-Oixdel ® against S. typhimurium and Brucella ovis was lowered compared to that on HW condition. As Vital-Oxidel ® possesses bactericidal efficacy against animal
