摘要:
The present invention provides a polypeptide antigen comprising amino acid sequence of adenylate cyclase protein of Bordetella pertussis bearing the following mutations: (i) substitution of the alanine residue in position 680 by a proline residue, and (ii) substitution of the valine residue in position 695 by a proline residue, or one or more fragments thereof, wherein said fragments comprise at least amino acids from position 374 to position 400, from position 500 to position 700, and from position 860 to position 1706. Said polypeptide antigen is suitable for use in a method of treatment and/or prevention of a disease caused by Bordetella pertussis, in particular against pertussis or whooping cough disease. The invention further provides a chimeric protein, a polynucleotide encoding the polypeptide antigen or chimeric protein, a vector and a host cell for the production of said polypeptide or protein.

[Problem to be Solved] The present invention provides a novel mucosal adjuvant. [Solution] The present invention provides a mucosal adjuvant composition containing at least a composition comprising molecules having a molecular weight in a range of 100 to 300 kDa obtained from cells or culture fluid of Bordetella bronchiseptica. Administration of the mucosal adjuvant composition to a non-human animal and the like at a surface of mucous membrane can enhance immunity at the surface of mucous membrane. Therefore, for example, preventive effects against trans-mucosal infection can be increased by administering an inactivated vaccine against trans-mucosal infection and the mucosal adjuvant composition to a non-human animal at a surface of mucous membrane. The present invention is effective for preventing trans-mucosal infections, including one or more infections of, for example, canine parainfluenza, canine adenovirus, canine coronavirus, canine parvovirus, canine distemper virus, canine herpesvirus, reovirus and pneumovirus.

The present invention relates to a recombinant genetically attenuated Bordetella strain expressing a hybrid protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitope or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated. The Bordetella strain is preferably a Bordetella pertussis strain, but may also be another Bordetella species, such as Bordetella bronchiseptica, Bordetella parapertussis or Bordetella avium. The invention further provides a life attenuated vaccine for the treatment of a mucosal or systemic infectious disease comprising a Bordetella strain as defined above intended to elicit a immune response against pathogens responsible for systemic or mucosal infections, including of the upper or lower respiratory tract. The present invention also relates to a method for prophylaxis of an infectious disease in a mammal, comprising administering to said mammal an effective amount of a vaccine comprising in a suitable vehicle a recombinant attenuated Bordetella strain expressing a fusion protein comprising the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitome or antigenic protein or protein fragment, different from FHA, wherein the gene coding for the native FHA protein is inactivated.
摘要:
The present invention relates to the use of toxoids prepared using a-dicarbonyl toxoiding reagents such as glyoxal, butanedione and phenylglyoxal. The toxoids may be prepared with low concentrations of toxoiding reagent and in short periods of time, often in as few as 24 hours, making the toxoiding reagents particularly advantageous when compared with traditional formaldehyde toxoiding. Toxoids prepared using dicarbonyl reagents such as phenylglyoxal are described and claimed as are pharmaceutical and vaccine compositions comprising the toxoids, methods of treatment using such compositions and antibodies generated by immunisation with the toxoid and methods of treatment using the antibodies so prepared or fragments of such antibodies.

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 present invention relates to a method for the enzymatic decarboxylation of aryl-substituted malonic acid (propanedioic acid) derivatives catalyzed by enzymes structurally and/or functionally related to arylmalonate decarboxylase (AMDase) as isolated from microorganisms of the genus Bordetella. The present invention also relates to novel enzymes with arylmalonate decarboxylase activity, useful for performing the claimed method, mutants thereof, corresponding coding sequences and expression systems, methods of preparing said novel enzymes, and screening methods for obtaining further suitable enzymes also having said arylmalonate decarboxylase activity.
