| 摘要 |
A method for counting cells and microorganisms in a fluid medium, particularly in food and biological fluids, by labelling with a coloured or fluorescent label which selectively labels the microorganisms and cells to be detected, and counting the labelled microorganisms and cells, wherein said coloured or fluorescent label is a stoichiometric label, particularly a DNA or RNA label, the microorganisms and cells are concentrated at the same time as or prior to counting by means of a fluid medium concentration step, and counting is achieved by measuring the overall brightness of the concentrated medium and comparing it with a calibration curve. |
