Abstract: A test strip for microorganism detection includes: a porous substrate, a surface of which a surface has a first color; and a microorganism detection composition, which is at least adhered to a part of a surface of the porous substrate or at least adhered to a part of a surface of the porous substrate and a part of an interior of the porous substrate. The microorganism detection composition includes: a plurality of colored particles having a second color different than the first color; and a plurality of specific peptides immobilized on the surfaces of the plurality of colored particles, in which the plurality of specific peptides connect the plurality of colored particles to each other to make the plurality of colored particles aggregate to cover the part of the surface of the porous substrate and present the second color on the part of the surface of the porous substrate.
