  • Publication number: 20240142363
    Abstract: A measurement method for quantitatively measuring amounts of at least two varieties of microorganisms in a test sample. The measurement method includes: producing a first sample by performing step dilution and division of the test sample; producing a second sample by amplifying nucleic acids of the microorganisms in the first sample; and performing hybridization of the second sample in a probe array including spots to which probes having complementary sequences to target nucleic acids specific to each of the varieties of the microorganisms are fixed; and identifying the varieties of the microorganisms based on light emission from the spots where the hybridization is performed and quantitatively measuring amounts of the microorganisms by a most probable number method.
