  • Publication number: 20190316170
    Abstract: A bacteria detection device moves a stage on which a detection chip is placed with a membrane filter fixed thereon by a first driving mechanism and a second driving mechanism in front-rear direction and in left-right direction so that an image of an upper surface of the membrane filter to which excitation light from a light emitter aligned with a imaging range by an imaging unit is taken. If bacteria to which a fluorescent label has been bound is captured on the upper surface of the membrane filter, the imaging unit can take an image of the bacteria as luminous points. A controller counts the luminous points in the image taken by the imaging unit so that the bacteria captured on the upper surface of the membrane filter can be detected.
