Abstract
A cell detector and detecting method enhance detection sensitivity for microbes according to the ATP method and reduce the detection period. The cell detector includes a sealing container having a culture portion for containing a culture medium containing the specimen, a sealable specimen introducing portion, and a luminescent reagent portion that emits light upon contact with the culture medium, a contact mechanism for controlling the contact between the culture medium and the luminescent reagent portion, a photodetector for detecting a luminescence resulting from the contact between the culture medium and the luminescent reagent portion, and a calculation unit for calculating a luminescent quantity from detection signals of the photodetector to determine cell proliferation on the basis of change in the luminescent quantity over time. The culture portion and the luminescent reagent portion are separately positioned, and the contact mechanism intermittently brings the culture medium and the luminescent reagent into contact.
