Process for obtaining specific probes of strain or specie

Abstract

The invention provides for the rapid and simple selection of fragments of DNA amplified by a non specific PCR reaction, fragments which are then used as specific probes of strain or specie, as desired. The fragments extracted from an agarose gel will be used as a probe in a hybridation on a solid medium whereon DNA samples have been immobilized, whether amplified or not, of bacterial strains to be identified. With the disclosed process it is possible to obtain specific probes applicable to the rapid identification of species in various fields.
