摘要:
The present invention is directed to a combination vaccine for Neisseria meningitidis comprising outer membrane proteins from serogroup B and oligosaccharides from serogroup C, and its use for the prevention or treatment of disease.
摘要:
The present invention relates to a composition comprising a diphtheria toxin (DT) variant, said DT variant comprises an amino acid sequence as recited in SEQ ID NO: 4 with one or more amino acid substitutions or deletions or combinations thereof, wherein at least one amino acid substitution or deletion is made within the regions selected from the group consisting of residues 7-9, 29-31 and 290-292 of SEQ ID NO: 4, and wherein said DT variant has cytotoxicity comparable to that of a DT molecule having a sequence of SEQ ID NO: 4.

摘要:
The present invention relates to a hybrid bacterial toxin subunit, to a hybrid bipartite bacterial toxin and to nucleic acid molecules comprising a nucleotide sequence encoding such bacterial toxins. Furthermore, the invention relates to vaccines comprising bacterial toxins and to their use in vaccines. Finally, the invention relates to methods for the preparation of such vaccines and to the use of such bacterial toxins for the manufacture of such vaccines.
摘要:
Provided are compositions and methods useful for modulating the activity of autoinducer synthase catalysts. A method for identifing modulators of the autoinducer synthesis reaction is also provided. Such modulators are useful for controlling bacterial growth and can be used for therapeutic treatment of bacterial infections particularly in immunocompromised subjects. They are also useful in treating disease states associated with autoinducer synthesis and biofilm development.
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:
The subject invention concerns novel Bacillus thuringiensis strains containing parasporal proteins with pesticidal properties against whitefly, aphid, jassid, and possibly other sucking insects of agronomic importance, and peptide sequences to these proteins that can be used to obtain structural genes. The spores or crystals of these microbes, or mutants thereof, are useful to control hymenopteran pests in various environments. The genes of the invention can be used to transform various hosts wherein the novel toxic proteins can be expressed.
摘要:
A DNA encoding an immunologically cross-reactive form of diphtheria toxin Fragment A, wherein the codons corresponding to Val-147 and Glu-148 of naturally occurring diphtheria toxin are deleted from the DNA.
摘要:
Glycoproteinic conjugates having trivalent immunogenic activity obtained by binding, by a covalent bond, to a protein selected among CRM 197, tetanus toxoid, and pertussis toxin, at least an oligosaccharidic hapten derived from the capsular polysaccharide of a gram-positive bacterium and at least an oligosaccharidic hapten derived from the capsular polysaccharide of a gram-negative bacterium, and wherein said oligosaccharidic haptens are previously activated by introducing terminal esters.
