Preferably, the invention relates to a nucleotide sequence according to the invention, characterized in that it codes for a specific polypeptide of Listeria innocua or monocytogerzes 4b or a fragment thereof. Among the said representative fragments, those having the nucleotide sequences corresponding to open reading frames, known ORFs sequences ORF for “Open Reading Frame” , generally between an initiation codon and a stop codon, or between two stop codons, and encoding polypeptides, preferably at least amino acids, such as, e. The polypeptides obtained by chemical synthesis and which may include corresponding non-natural amino acids are also included in the invention. More preferably, the vaccine composition comprising polypeptides according to the invention will be administered repeatedly, so spread out over time, intradermally or subcutaneously. In particular, it is possible to study and determine the polymorphism regions between said strains.

The amplified nucleotide fragments may be used as reagents in hybridization reactions in order to highlight the presence l4, 30079 a biological sample, of a sequence complementary to target nucleic acid to that of said amplified nucleotide fragments.
Such mlnton method according to the invention-including the identification of specific sequences of L. To achieve this, the DNA of all or part of the genes of L.
Please click here to find the nearest dealer. Among the said representative fragments, those having the nucleotide sequences corresponding to open reading frames, known ORFs sequences ORF for “Open Reading Frame”generally between an initiation codon and a stop codon, or between two stop codons, and encoding polypeptides, preferably at least amino mintin, such as, e.
Using the probes of the invention, a reverse transcriptase-type enzyme to obtain a cDNA from the mRNA contained in the biological sample. Indeed, the presence of the expression product of a gene recognized by an antibody specific for said expression product can be detected by the presence of an antigen-antibody complex formed after contacting the strain of Listeria innocua or monocytogenes 4b or the microorganism associated with an antibody of the invention.
The invention also relates to plants and animals, except man, which comprise a transformed cell of the invention. The polypeptide mp may correspond to isolated or purified fragments naturally present in the Listeria strains, or fragments that can be obtained by cleavage of imnton polypeptide by a proteolytic enzyme such as trypsin or chymotrypsin or collagenase, with a reagent chemical cyanogen bromide, CNBr or by placing the said polypeptide in a highly acidic environment e.
These are preferably sequences complementary sequences are capable of hybridizing specifically with the reference sequences. By representative fragment is meant in particular a nucleic acid sequence encoding a biologically active fragment of a polypeptide as defined below. Vaccines prepared from synthetic monton or from genetically modified microorganisms expressing heterologous antigens are being tested.
This very high value was chosen as it best allows 15 discriminating genes orthologs of genes paralogs Fitch, WS, Syst. Moreover, when the same plant is contaminated by two successive events it is important to show with certainty whether these are two independent contamination or if the same strain is responsible for these two events.

At the extreme, some strains could be considered hazardous and other harmless as Listenia innocua. Comparison of the genomes a Identification L. Those skilled in the art will recognize, from these specific sequences according to the invention, draw the primers or probes, produce specific peptides or antibodies directed against these peptides necessary for the implementation of these diagnostic methods or diagnostic kit development as presented below or standards. The vectors according to the invention are, for example plasmid or viral vectors.
By following this procedure, you can introduce the webcam to your device. In the present description, the terms polypeptides, polypeptide sequences, peptides and proteins are interchangeable.
The genomic sequence of L. Thus, the nucleic sequences of the kmp also includes PNAs peptide nucleic acids. Is minon to denote “best alignment” or “optimal alignment”, the alignment for which the percentage identity determined as below 5 is the highest. Preferably, the invention relates to a nucleotide sequence according to the invention, characterized in that it encodes a polypeptide of Listeria innocua munton monocytogenes 4b or a fragment thereof involved in mml biosynthesis of cofactors prosthetic groups and carriers.
The invention also relates to nucleic acids capable of being obtained mintln amplification using primers according to the invention. Preferably, the invention relates to a nucleotide sequence according to the invention, characterized in that it encodes a polypeptide of Listeria innocua or monocytogenes 4b or a fragment thereof involved in energy metabolism.
An alternative method, but less efficient automated ribotyping, presents a cost analysis, high limiting its use. Preferably, the invention relates to a nucleotide sequence according to the invention, characterized in that it encodes a polypeptide of Listeria innocua or monocytogenes 4b or a fragment thereof involved in adaptation to atypical conditions. Moreover recent data from the laboratory to the sequencing of an epidemic strain of L.
Minton – Products
The mkp invention provides all the naturally active sequences in L. However, although some areas have not been cloned at the bank, because of lethalities problems in Escherichia coli, these regions can easily be amplified and identified by the skilled person, using specific oligonucleotide sequences of ends of the different clones that form contigs.
In another aspect, preferably, the invention relates to a polypeptide according to the invention mintoh, characterized in that it is a polypeptide Lister ia innoczra or monocytogenes 4b or a fragment thereof involved in the metabolism of fatty acids and phospholipids. In another aspect, preferably, the invention relates to a polypeptide according to the invention, characterized in that minhon is a polypeptide Listeria monocytogenes 4b or innoczra 25 or a fragment thereof involved in the nucleotide metabolism, purine, pyrimidine or nucleosides.
Self Sustained Sequence Replication technique described by Guatelli et al.
