Bactericidal ability on agar plate was tested, using <i>Staphylococcus aureus</i>, <i>Pseudomonas aeruginosa</i>, <i>Bacillus cereus</i>, and <i>Enterococcus faecalis</i> as follows : the medium containing a certain amount of each bacterium was put onto an agar plate and smeared. Plates were kept in a closed chamber (inner volume 14.4m<sup>3</sup>) ora glove box (inner volume 0.2m<sup>3</sup>), with one of the devices run for 2 hours.  Plates not exposed to any device were used as controls.  Each plate was retrieved and put in an incubator to count the number of bacterial colonies formed on the plate. <BR>There was no significant difference in the number of colonies on plates exposed to devices compared to control, in the number for all devices, or in all bacteria tested in experiments in the 14.4m<sup>3</sup> chamber.  These results strongly suggest that these devices have almost no bactericidal effect, at least in space exceeding this volume. <BR>Colony formation was suppressed in the glove box in all devices and in all bacteria tested except <i>P. aeruginosa</i>, although the degree of suppression differed among experiments.  The colony formation suppression mechanism was analyzed, and indicated that : colony formation did not change even after the removal of Plasmacluster ions, Nanoe particles, or negative ions from the air, while colony formation was decreased drastically by the removal of ozone from space, which was revealed to be generated inevitably during device operation.  These results strongly suggest that the bactericidal effect seen only on the agar plate in narrow space was explained by ozone released in space as a by-product, not by special materials as advertising claimed.  <BR>It is thus important to analyze the effect of special materials such as those done in this study and to suggest the involvement of ozone as the true cause, as have been done in this study, in evaluating bactericidal effect or viral inactivation as advertised by these companies."},{"@language":"ja","@value":"本邦では，空中へ特殊な物質の放出により環境中においてウイルス不活化や殺菌の効果をもたらすとする複数の電気製品が市販されており，寒天培地上に塗布した細菌に対する殺菌効果も謳っている．そこで本研究では，プラズマクラスター，ナノイー，ビオンの3 機種について，腸球菌，黄色ブドウ球菌，緑膿菌，セレウス菌での追試を試みた．一定数の生菌含有菌液を普通寒天平板上に塗布し，14.4m<sup>3 </sup>閉鎖空間に対象機器とともに置き，機器を2 時間運転させた後培養し，出現するコロニー数を，非運転環境下においた対照のそれと比較した．その結果，調べた3 機種，4 種の菌のすべての組み合わせで，形成されるコロニーの数は対照のそれと変わらなかった．一方，細菌を塗布した寒天培地を容積0.2m<sup>3 </sup>の密閉グローブボックス内に置き，同様の実験を行ったところ，3 機種すべてが，腸球菌と黄色ブドウ球菌のコロニー形成を，程度の差はあれ対照と比べて有意に減少させ，一方緑膿菌については減少させなかった．前二者に対するコロニー形成抑制／殺菌の機序について，これらの機器が放出するオゾンが原因である可能性を検討した．その結果，殺菌効果は，それらが発生させるイオンや特殊微粒子を除去しても変わらず，一方で発生するオゾンを除去すると激減した． 以上の成績により，調べた電気製品には，1）通常の生活空間のような広い空間における使用では，ほとんど殺菌効果が期待できないこと，しかし，2）きわめて狭い空間における寒天培地上のある種の細菌という限定的な対象に対しては，ある程度の殺菌作用は認められること，だが，3）そうした効果は，一義的には，それらの機器が放出している特殊物質というより，それらが同時に放出しているオゾンによる殺菌効果で十分説明可能であること，が明らかになった．今回対象となった機器のみならず，こうした類の殺菌効果を謳う電気製品については，オゾンの関与を疑う必要があろう．"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001204243188608","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000409203904"},{"@type":"NRID","@value":"9000411813336"},{"@type":"NRID","@value":"9000283277277"},{"@type":"NRID","@value":"9000340442647"},{"@type":"NRID","@value":"9000411001001"},{"@type":"NRID","@value":"9000324651671"},{"@type":"NRID","@value":"9000303996083"},{"@type":"NRID","@value":"9000375912643"},{"@type":"NRID","@value":"9000361700426"},{"@type":"NRID","@value":"9000283155845"},{"@type":"NRID","@value":"9000324653661"},{"@type":"NRID","@value":"9000024258840"},{"@type":"NRID","@value":"9000411806913"},{"@type":"NRID","@value":"9000314064402"},{"@type":"NRID","@value":"9000314064496"},{"@type":"NRID","@value":"9000019056685"},{"@type":"NRID","@value":"9000261045706"},{"@type":"NRID","@value":"9000411826884"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/hide1955"}],"foaf:name":[{"@language":"en","@value":"NISHIMURA  Hidekazu"},{"@language":"ja","@value":"西村 秀一"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Virus Research Center, Clinical Research Division, Sendai Medical Center, National Hospital Organization"},{"@language":"ja","@value":"独立行政法人国立病院機構仙台医療センター臨床研究部ウイルスセンター"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"03875911"},{"@type":"LISSN","@value":"03875911"},{"@type":"EISSN","@value":"1884569X"},{"@type":"NDL_BIB_ID","@value":"000000004450"},{"@type":"ISSN","@value":"03875911"},{"@type":"NCID","@value":"AN00047715"}],"prism:publicationName":[{"@value":"感染症学雑誌"},{"@language":"ja","@value":"感染症学雑誌"},{"@language":"en","@value":"Kansenshogaku Zasshi"},{"@value":"感染症誌"},{"@language":"en","@value":"kansenshogakuzasshi"},{"@language":"ja","@value":"感染症誌"},{"@language":"en","@value":"J.
