SIMULTANEOUS DETECTION, IDENTIFICATION AND DIFFERENTIATION OF EU BACTERIA USING A HYBRIDIZATION ASSAY

摘要

The present invention relates to a method for detection and identification of at least one micro-organism, or for the simultaneous detection of several micro-organisms in a sample, comprising the steps of: (i) if need be releasing, isolating or concentrating the polynucleic acids present in the sample; (ii) if need be amplifying the 16S-23S rRNA spacer region, or a part of it, with at least one suitable primer pair; (iii) hybridizing the polynucleic acids of step (i) or (ii) with at least one and preferably more than one of the spacer probes as mentioned in table la or equivalents of thereof, under the appropiate hybridization and wash conditions, and/or with a taxon-specific probe derived from any of the spacer sequences as represented in figs. 1-103 under the same hybridization and wash conditions; (iv) detecting the hybrids formed in step (iii) with each of the probes used under appropiate hybridization and wash conditions; (v) identification of the micro-organism(s) present in the sample from the differential hybridization signals obtained in step (iv).
