Method for detecting, identifying, or counting microorganisms, and system using same

A device for detecting, identifying or counting microorganisms, comprising:

• (a) a slide having disposed on a surface thereof a metering chamber capable of receiving a sample solution containing microorganisms, wherein the metering chamber comprises an upper plate and a lower plate, and a chamber interior formed by coupling of the upper plate with the lower plate has a depth of 1 to 200 μm and
• (b) a centrifugal means configured to apply a centrifugal force in a direction perpendicular to the lower plate of the metering chamber containing the sample solution, thereby forming a focal plane in the metering chamber;
• (c) a light source configured to irradiate light onto the slide;
• (d) an imaging means configured to acquire an image produced by the light source;
• (e) an image processor configured to detect, identify or count microorganisms in a predetermined volume of the metering chamber based on the image acquired by the imaging means;
• and
• (f) a display means configured to display the results of detecting, identifying or counting the microorganisms.
