Abstract

In the present study, using biological information of bacteria and biochemical information of chlorine dioxide gas, Gram-positive bacteria, e.g., Alloiococcus otitis, Erysipelothrix rhusiopathiae, Staphylococcus caprae, Staphylococcus lentus, and gram-negative bacteria, e.g., Acinetobacter baumannii complex, Aeromonas salmonicida, Brucella melitensis, Oligella ureolytica were used whether a plastic kit to release ClO2 gas could inhibit their growth. Overall, chlorine dioxide gas showed about 99% inhibition of bacterial growth, with less than 10 CFU. However, it was found that Gram positive Alloiococcus otitis and Gram negative Aeromonas salmonicida had more than about 50 CFU. When comparing the results of experiments with several bacteria, it suggested that the concentration of chlorine dioxide gas would be at least 10 ppm to 400 ppm for the bacterial inhibition. The results of this study could be used as basic data to evaluate the clinical usefulness of chlorine dioxide gas. If this study helps with prior knowledge to help clinicians to recognize and prevent the presence of micro-organisms that cause infections in hospitals, it would be helpful for activities such as patient care as a convergence field. In the future, it is considered that the research results will be the basis for rapidly inhibiting the microbes infected with patients by utilizing data of the information of the microbes that are inhibited for chlorine dioxide gas.

본 연구에서, 세균의 생물학적 정보와 이산화염소 가스의 생화학적 정보들을 활용하여, 그람 양성 세균인 Alloiococcus otitis, Erysipelothrix rhusiopathiae, Staphylococcus caprae, Staphylococcus lentus 및 그람 음성 세균인 Acinetobacter baumannii complex, Aeromonas salmonicida, Brucella melitensis, Oligella ureolytica에 대한 이산화염소가스의 성장 억제 효과를 분석하였다. 전체적으로, 이산화염소 가스는 10 CFU 미만으로 세균의 성장을 약 99 % 억제하였다. 하지만, 그람 양성인 Alloiococcus otitis 및 그람 음성인 Aeromonas salmonicida는 약 50 CFU 이상인 것으로 밝혀졌다. 여러 세균과의 실험 결과를 비교할 때, 이산화염소 가스의 농도는 세균 억제에 대해 10 ppm 내지 400 ppm 일 것이라고 제안한다. 이 연구의 결과는 이산화염소 가스의 임상적 유용성을 평가하기 위한 기본 데이터로 사용될 수 있을 것이다. 이 연구가 임상에 있는 근무자가 병원에서 감염을 일으키는 미생물의 존재를 인식하고 예방하는 사전 지식에 도움이 되는 경우, 융합분야 중, 임상에서처럼 환자 치료와 같은 활동에 도움이 될 것이다. 향후에, 이산화염소 가스에 대해 억제되는 미생물들의 정보의 데이터를 활용하여, 환자에게 감염된 미생물들을 신속히 억제하는데 기초가되는 연구결과가 될 것으로 사료된다.
