摘要:
The invention relates to polyepitope carrier proteins that comprise at least five CD4+T cell epitopes, for conjugation to capsular polysaccharides. The carrier proteins are use useful as components of vaccines that can elicit a T-cell dependent immune response. These vaccines are particularly useful to confer protection against infection from encapsulated bacteria in infants between the ages of 3 months and about 2 years.
摘要:
This application relates to Group B Streptococcus (“GBS”) vaccines comprising combinations of GBS polypeptide antigens where the polypeptides contribute to the immunological response in a recipient. Preferably, the compositions of the invention comprise a combination of two or more GBS antigens, wherein said combination includes GBS 80 or a fragment thereof. In one embodiment, the combination may consist of two to thirteen GBS antigens selected from an antigen group consisting of GBS 80, GBS 91, GBS 104, GBS 184, GBS 276, GBS 305, GBS 322, GBS 330, GBS 338, GBS 361, GBS 404, GBS 690, and GBS 691.
摘要:
The published genomic sequence of Chlamydia pneumoniae reveals over 1000 putative encoded proteins but does not itself indicate which of these might be useful antigens for immunisation and vaccination or for diagnosis. This difficulty is addressed by the invention, which provides a number of C. pneumoniae protein sequences suitable for vaccine production and development and/or for diagnostic purposes.
摘要:
This invention provides, among other things, protein, polypeptides, and fragments thereof, derived from bacteria Neisseria meningitidis B. Also provided are nucleic acids encoding for such proteins, polypeptides, and/or fragments, as well as nucleic acids complementary thereto (e.g., antisense nucleic acids). Additionally, this invention provides antibodies which bind to the proteins, polypeptides, and/or fragments. This invention further provides expression vectors useful for making the proteins, polypeptides, fragments, and/or nucleic acids, for use as vaccines, diagnostic reagents, immunogenic compositions, and the like. Methods of making the compositions and methods of treatment with the compositions are also provided. This invention also provides methods of detecting the proteins, polypeptides, fragments and/or nucleic acids.

摘要:
The invention relates to the identification of a new adhesin islands within the genomes of several Group A and Group B Streptococcus serotypes and isolates. The adhesin islands are thought to encode surface proteins which are important in the bacteria's virulence. Thus, the adhesin island proteins of the invention may be used in immunogenic compositions for prophylactic or therapeutic immunization against GAS or GBS infection. For example, the invention may include an immunogenic composition comprising one or more of the discovered adhesin island proteins.
摘要:
The mutants of neutral protease (NP) described can retain their enzymatic activities at temperatures at which wild-type neutral protease becomes inactive, the mutants being characterised in that the Gly 189 and/or Gly 147 residues of the aminoacid sequence of NP are replaced by different residues selected from the natural aminoacids.Mutagenised genes of neutral protease which code for the mutants, recombinant plasmids containing the genes, and strains of Bacillus transformed by the plasmids are also described. The mutants of neutral protease having the characteristics described above are particularly useful in the food sector.
摘要:
Novel plasmid vectors are described, for expression in Escherichia coli and/or Bacillus subtilis, in which the gene which codes for a heterologous protein is placed under the control of a promoter of the erythromycin gene which permit the organisms transformed with the abovementioned plasmids to express the heterologous protein in high yields.
摘要:
Nucleotide sequences capable of inducing high levels of translation of a heterologous gene in Bacillus subtilis and Escherichia coli and a method of preparing heterologous proteins comprising cultivation in a suitable culture medium of cells of Bacillus subtilis and Escherichia coli transformed by hybrid plasmids in which the nucleotide sequence is situated between the ribosome recognition site and the starting triplet (ATG) of the coding structural gene for the desired proteins.
