METHOD OF CULTIVATED MICROBIOLOGICAL OBJECTS COUNT Russian patent published in 2010 - IPC C12Q1/04 C12Q1/06 C12M1/00 G01N15/14 

FIELD: medicine.

SUBSTANCE: cultivated microbiological objects count is ensured by the measurements of their morphological compositions by determining the size distribution of microorganism cells in a nutrient fluid by variation of scattered light intensity. The fluid flow is sounded with monochromatic coherent light; interaction signal of probe radiation and analysed microbiological objects are recorded by the measurement of amplitude and duration of scattered light pulses by analysed particles; and functions derived from the measurements are plotted in the form of two-dimensional distribution of specified amplitudes and durations expressing statistic parameters of light scattering intensity by particles. After said functions, the size distribution of analysed cultivated microbiological objects and decay products of the nutrient fluid is derived.

EFFECT: higher measurement accuracy due to eliminated error caused by foreign particles that are decay products of the nutrient fluid in cultivation of the analysed microbiological objects.
