METHODS OF SEPARATION AND CHARACTERISTIC OF MICROORGANISMS BY MEANS OF IDENTIFIER Russian patent published in 2014 - IPC G01N33/50 G01N33/68 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of microbiology, namely to a method of microorganism characteristic. The essence of the method consists in the following: (a) obtaining a sample to be tested, about which it is known that it contains or can contain microorganisms; (b) layering the tested sample on a density buffer in a container, where the said density buffer possesses a uniform density from approximately 1.025 to approximately 1.120 g/ml; (c) addition of an identifier into the said tested sample and/or into the said density buffer; (d) centrifugation of the said container in order to separate microorganisms from other components of the said tested sample and to form a deposit of microorganisms; (e) spectroscopic analysis of the deposit and/or the said one or more than one identifier with obtaining measurements, which characterise the microorganisms, where the said spectroscopic analysis is carried out when the said deposit is located in the said container; and (f) characteristic of the microorganisms in the deposit on the basis of the obtained measurements and/or the presence or absence of the said identifier or a metabolised form of the said identifier in the deposit, where the said microorganisms are characterised by one or more classification models, selected from the group, consisting of Gram groups, clinical Gram groups, therapeutic and functional groups.

EFFECT: application of the claimed invention makes it possible to increase the accuracy of the microorganism characteristic.
