Probe for DNA and a process for the detection of shigellae and entero-invasive strains of Escherichia coli

摘要

The invention concerns a probe for the detection of shigellae and entero-invasive E. coli, containing a nucleic acid sequence originating from the 140 Mdal virulence plasmid of the M 90 T strain of Shigella flexneri; having a maximum size of around 27 kb and inlcuding all or part of the 27 kb Bam HI fragment. This probe permits the in vitro diagnosis of syndromes of dysentery or diarrhea, of the Shigellosis type.
