A method for accurately counting desired cells or microorganisms (viable bacteria) in a sample fluid in which contaminants are included is provided. One or plural types of membrane-permeable fluorochromes whose fluorescence amount is amplified by binding to a nucleic acid and glycerin are added to a sample fluid containing cells or microorganisms to be counted and allowed to stand for a certain time. Glycerin is added before or after or simultaneously with the mixing of the sample fluid and the fluorochrome(s). The cells or microorganisms to be counted are counted by staining the cells or microorganisms to be counted, followed by irradiating with light having a specific wavelength to detect the fluorescence emitted from the cells or microorganisms.

Method for testing microorganism or the like and testing apparatus therefor

Provided are a microorganism testing chip capable of suppressing self-fluorescence and enhancing mass productivity, and a microorganism testing device using the same. The microorganism testing chip includes a main body and a fungus body detection unit mounted on the main body. The main body has a detection window frame portion which is a through-hole or a pass-through groove. The fungus body detection unit is disposed to cover the detection window frame portion and has a fungus body detection flow path connected to flow paths provided in the main body. The fungus body detection unit includes a cover member and a flow path member, and is formed by attaching these two members to each other. The flow path member has a groove. By attaching the two members to each other, the groove of the flow path member serves as the fungus body detection flow path.

Microorganism testing device and microorganism testing chip

A stab proof vest, wherein at least a portion of the stab proof vest includes a plurality of elements, and a coupling member for coupling adjacent the elements together. Each side of the elements is provided with at least one projection and at least one depression adjacent to the projection, and a coupling hole into which the coupling member is inserted. The projection of one element is engaged with the depression of an adjacent element. The common coupling member is inserted into each the hole of adjacent elements and is secured thereto in order to couple the adjacent elements.
