UNIV PARIS XIII PARIS NORD [FR]

Resumen de: WO2017178554A1

The present invention relates to methods and kits for the rapid detection of the Escherichia coli O25b-ST131 clone. The inventors have isolated a podoviridae bacteriophage (LM33_P1) infecting the E. coli strain LM33 isolated from ventilator associated pneumonia and which belongs to clone STI3I-025b. By testing different strains of E coli belonging to 129 others various distinct serotypes (including twelve O25a) the inventors found that bacteriophage LM33_P1 is able to infect exclusively O25b strains (none of non-O25b strains could be infected by LM33_P1). The inventors have determined that the specificity displayed by bacteriophage LM33_P1 to infect only 025b serotype strains is based on a very specific polypeptide (Gp17) used by LM33_P1 to attach the bacterial cell via LPS molecule. In particular, the present invention relates to a polypeptide comprising an amino acid sequence having at least 80% of identity with the amino acid sequence set forth in SEQ ID NO:1.
