    Assignee: Institut Pasteur
    Inventors: Michel Arthur, Sylvie Dukta-Malen, Catherine Molinas, Patrice Courvalin
  • Polypeptides implicated in the expression of resistance to glycopeptides, in particular in Gram-positive bacteria, nucleotide sequence coding for these polypeptides and use for diagnosis
    Publication number: 20050112641
    Abstract: The invention relates to a composition of polypeptides, characterized in that it contains at least one protein or part of a protein selected from the sequences of amino acids identified in the list of the sequences as SEQ ID NO 1 (VanH), SEQ ID NO 2 (VanA), SEQ ID NO 3 (VanX) or SEQ ID NO 19 (VanC), or any protein or part of a protein recognized by the antibodies directed against VanH, VanA, VanX or VanC, or any protein or part of a protein encoded in a sequence hybridizing with one of the nucleotide sequences identified in the list of the sequences as SEQ ID NO 8, SEQ ID NO 9 or SEQ ID NO 10 or with one of the following sequences V1 or V2 under stringent or only slightly stringent conditions: V1: GGX GAA GAT GGX TCX TTX CAA GGX ??G ??C AG C ??G A V2: AAT ACX ATX CCX GGX TTT AC ??C T ??C C The invention also relates to the nucleotide sequences coding for these polypeptides as well as their utilization for the diagnosis of resistance to the glycopeptides.

  • Polynucleotides and their use for detecting enterococci and streptococci bacterial strains
    Patent number: 6054269
    Abstract: Polynucleotides and oligonucleotides for identification of species of the Streptococcus genus and the Enterococcus genus are provided. The polynucleotides and oligonucleotides are useful as probes and primers. Polypeptides expressed by the polynucleotides and oligonucleotides are useful for the preparation of monoclonal and polyclonal antibodies that recognize the polypeptides.

  • Polypeptides implicated in the expression of resistance to glycopeptides, in particular in gram-positive bacteria, nucleotide sequence coding for these polypeptides and use for diagnosis
    Patent number: 6013508
    Abstract: The invention relates to compositions and nucleic acids encoding polypeptides involved in the expression of resistance to glycopeptides, in particular to vancomycin and/or teicoplanin. The invention also relates to vectors containing said nucleic acids, transformed host cells and their use for the diagnosis of resistance to glycopeptides.
    Type: Grant
    Filed: November 28, 1997
    Date of Patent: January 11, 2000

  • Probes for the detection of nucleotide sequences implicated in the expression of resistance to glycopeptides, in particular in gram-positive bacteria
    Patent number: 5871910
    Abstract: The invention relates to isolated polynucleotides and probes which are optionally labelled and which hybridize with polynucleotides encoding polypeptides implicated in the bacterial resistance to vancomycin, teicoplanin and to both vancomycin and teicoplanin. The invention also relates to the utilization of these polynucleotide probes for the diagnosis of resistance to the glycopeptides.
