Moreover recent data from the laboratory to the sequencing of an epidemic strain of L. The vector used for construction of the library, pcdna2. To use effectively the Caller Identity feature on the telephones, you should use the alcaline batteries. Such determining may comprise a polypeptide or a fragment thereof according to the invention in glycosylated form used to obtain immunogenic compositions capable of inducing the synthesis of antibodies directed against multiple epitopes. The present invention also relates to the genomic sequence and nucleotide sequences encoding polypeptides of Listeria inrzocua, such as cellular envelope polypeptides, secreted or specific, or involved in the metabolism and the replication process, as well as vectors including the said sequences and cells or animals transformed with these vectors. The probe hybridization technique can be performed in various ways Matthews et al. S 19

One can also use insect cells or plant cells. One can, for example, refer to the technique described in US Patent No. In the mice, in which a weight dose of the vaccine composition 5 comparable to the dose used in humans is administered, the antibody reaction is tested by collecting serum followed by a study of the formation of a complex between the antibody present in the serum and the antigen of the vaccine composition, according to the usual techniques.
In particular, it is possible to study and determine the polymorphism regions between said strains. Said hybrid nucleotide sequences coding for a hybrid polypeptide as well as the hybrid polypeptides according to the invention characterized in that they are recombinant polypeptides obtained by the expression of said hybrid nucleotide sequences are also part of the invention. The labeling of the primers or probes according to the invention is carried out with radioactive elements or with nonradioactive molecules.
Using the probes of the invention, a reverse transcriptase-type enzyme to obtain a cDNA from the ,inton contained in the biological sample. The invention also relates to the polypeptides encoded by a nucleotide sequence according to the invention, preferably by a representative fragment of the above sequences and corresponding to an ORF sequence. Indeed, a hybrid polypeptide according to the invention enables potentiation of the immune response, against the polypeptide according to the invention coupled to the immunogenic molecule.
To use effectively the ,mp Identity feature on the ninton, you should use the alcaline batteries.
It is thus possible to replace leucine by valine or isoleucine, aspartic acid by glutamine acid, glutamine by asparagine, arginine by lysine, ete. A single-stranded template RNA or DNA sequences to be analyzed is advantageously prepared according to conventional methods, from PCR amplified products according to type techniques. In this case, a probe, called a “capture probe” is immobilized on a support and serves to capture, by specific hybridization, the target nucleic acid mml from the biological test sample and the target nucleic acid is then detected using a second probe, called a “detection probe”, labeled with an easily detectable element.
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 transport processes and protein binding. In the present description, the terms polypeptides, polypeptide sequences, peptides and proteins are interchangeable. It allows the determination of all sequences expressed in L.
Said mutations may lead to inactivation of ninton gene, or especially when they are located in the regulatory elements of said gene, an overexpression thereof.

The genome of this bacterium is circular and includes about 3, kilobases. Clinical manifestations of listeriosis include meningitis, meningoencephalitis, abortions and septicemia.
The vaccine compositions comprising nucleotide sequences or vectors into which are inserted said sequences are in particular described in 30 international application No. To set said maximum homology window, one can use the same algorithms as for the nucleic acid sequences. Are also meant by microorganism associated in the present invention, any microorganism having the nucleotide sequences or polypeptides according to the invention.
The present invention provides all the naturally active sequences in L. The representative fragments according to the invention may also be probes or primers which can be used in methods of detection, identification, assay or amplification of nucleic sequences.
After hybridization, the excess probe is removed and the hybrid molecules formed are detected by the appropriate method measurement of the radioactivity, of the fluorescence or of the enzymatic activity linked to the probe.
Is intended to denote a DNA chip or high density filter, a support on which are fixed DNA sequences, each of which may be identified by its geographical location.
Those skilled in the art knows the processes of chemical synthesis, for example the techniques employing solid phases see notably Steward et al. Genes common to L.

The annealing temperature of the oligonucleotides with the corresponding seats on the DNA should be approximately the same for each oligonucleotide. The reference sequences used were: A vector according to the invention carrying such a sequence can therefore advantageously be used for the production of recombinant proteins, intended to be secreted.
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.
Please click here to find the nearest dealer. The vaccine compositions comprising nucleotide sequences will preferably comprise also the nucleotide sequences encoding a polypeptide or a fragment thereof corresponding to a protein, or a fragment thereof, of the cell envelope of Listeria. By representative fragment is meant in particular a nucleic acid sequence encoding a biologically active fragment of a polypeptide as defined below.
