Abstract:
BACKGROUND: Disinfection is essential for the prevention of hospital infection. HICLO-S (Soosan environment Co., Yongin, Korea), one of the electrolyzed oxidized water was recently developed as a disinfectant. This is not costly and does not cause any clinical problems and environmental pollution. We evaluated the disinfective activity of HICLO-S against several clinical isolates of bacteria and yeasts. METHODS: 25 strains of bacteria and two strains of yeast were exposed to HICLO-S (30 & 50 ppm HICLO-S) disinfectant for the various periods (0.5, 1, 2, 4, 8, 10, 15, 20 minutes). After the exposure to HICLO-S disinfectant, 0.01 mL of mixture of microorganisms and HICLO-S was inoculated into brain-heart infusion broth or onto Sabouraud dextrose agar and incubated at 35degrees C for 48hours. RESULTS: All strains of bacteria and yeast were killed within 30 seconds after an exposure to 30 ppm of HICLO-S. All of three strains of spore forming Bacillus subtilis were killed within 4 minutes after an exposure to 30ppm of HICLO-S, but all of three strains were killed within 30 seconds in 50 ppm of HICLO-S. CONCLUSIONS: This study showed that HICLO-S disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital, but less effective against spore-forming bacteria. It may be recommended that HICLO-S should he used for the effective disinfection of skin, instruments and hospital floors.
