摘要:
A genetically attenuated Bordetella pertussis strain includes a mutated pertussis toxin (ptx) gene, and a heterologous ampG gene, and a hybrid protein including the N-terminal fragment of filamentous haemagglutinin (FHA) and a heterologous epitope or antigenic protein or protein fragment, different from FHA. The strain can be used in an attenuated vaccine for the treatment or prophylaxis of an infectious disease.
摘要:
The present invention relates to a life attenuated Bordetella pertussis vaccine which is deficient for tracheal cytotoxin (TCT), pertussis toxin (PTX), and dermonecrotic toxin (DNT) for prophylaxis or treatment of an allergen-driven airway pathology.
摘要:
A mutated Bordetella strain comprising at least a mutated ptx gene, a deleted or mutated dnt gene and a heterologous ampG gene is provided. The attenuated mutated Bordetella strain can be used in an immunogenic composition or a vaccine for the treatment or prevention of a Bordetella infection. Use of the attenuated Bordetella strain for the manufacture of a vaccine or immunogenic composition, as well as methods for protecting mammals against infection by Bordetella are also provided.

摘要:
The invention relates to compositions and vaccines that include a mutated Bordetella strain for treating or preventing an influenza infection in a mammal. In addition, the invention further provides methods for protecting a mammal against infection by influenza and/or eliciting an immune response against an influenza virus in a mammal using the composition or vaccine.

摘要:
A method of reducing or preventing the development of airway inflammation in a subject includes the step of infecting the respiratory tract of a subject an amount of a composition including a pharmaceutically acceptable carrier and live attenuated pertactin-deficient Bordetella bacteria sufficient to colonize the respiratory tract of the subject. The step of infecting the subject with the live attenuated pertactin-deficient Bordetella bacteria results in reduction or prevention of the development of airway inflammation in the subject.

摘要:
Recombinant Mycobacteria (rMyc) which contain sequences encoding a heparin-binding hemagglutinin (HBHA) fission protein are provided, as are methods of making and using the rMyc and the fusion protein. The fusion protein includes an amino terminal mycobacterial antigen Ag85B leader peptide and transcription of the fusion protein is driven by an Ag85B promoter sequence. The recombinant fusion protein is produced in abundance by the rMyc, is post-translationally methylated, and is highly antigenic.
