PROBLEM TO BE SOLVED: To deactivate a microorganism such as a bacterium, a fungus, and algae on a surface of a hard material of housing, furniture, equipment or the like, or to modify a receptor, a carrier and an enzyme that protrude from a cell membrane and a cell wall of the microorganism to inhibit each function.SOLUTION: An antibacterial treatment agent includes as an antibacterial base agent a 2-mercaptopyridine-N-oxide salt, a homologous derivative formed by substituting/modifying another group for hydrogen of a 3-6 position of the pyridine ring of the 2-mercaptopyridine-N-oxide salt, or a homologous derivative formed by substituting a pyrimidine ring for the pyridine ring. The antibacterial treatment agent is added to, impregnated in, or coated on an antibacterial treatment target by uniformly distributing so as to be 1 mg or more per 1 m2 of a surface area of the antibacterial treatment target.COPYRIGHT: (C)2015,JPO&INPIT【課題】住宅・家具・備品等の硬質材表面における細菌、真菌(カビ)並びに藻類などの微生物を不活性化し、もしくはこれら微生物の細胞膜・細胞壁外に突出した受容体・輸送体・酵素を変性させるなどして各機能を阻害する。【解決手段】2-メルカプトピリジン-N-オキシド塩、又は、前記2-メルカプトピリジン-N-オキシド塩のピリジン環の3~6位にある水素が他基に置換・修飾された同族誘導体、又は、前記ピリジン環がピリミジン環に置換された同族誘導体を抗菌基剤として含む抗菌処理薬剤を、抗菌処理対象物の表面積1m2当たり1mg以上になるように均一に分布させて抗菌処理対象物へ添加、含浸又は塗付を行うことを特徴とする。【選択図】図1
