DEVICE FOR DETERMINING LIVE/DEAD BACTERIAL STATE, AND METHOD FOR DETERMINING LIVE/DEAD BACTERIAL STATE USING SAID DEVICE

Provided is a device for determining the live/dead state of microorganisms, with which it is possible to ascertain the accurate state of live microorganisms/dead microorganisms via a captured image in a relatively easy operation with which ascertaining the state of the microorganisms is more accurate than conventional methods. This device for determining the live/dead state of the microorganisms comprises: a case body in which a measurement mechanism is housed; an opening/closing lid body that allows a microbe-base insertion port formed in the case body to be opened and closed; and the measurement mechanism, which is housed in the case body and is configured to measure the number of microorganisms. The measurement mechanism comprises: a microbe-base holding mechanism that inserts and fixes a microbe-base on which the bodies of the microorganisms collected from a specimen are placed; an excitation light irradiating mechanism configured so as to be capable of focusing and irradiating an excitation light toward the cells of the microorganisms on the microbe-base; an imaging camera disposed above the microorganisms on the microbe-base; and an XY-axes adjustment mechanism that minutely adjusts and moves, in the XY-axes, an XY stage supporting the microbe-base holding mechanism and comprising two separately moving layers.
