摘要:
This invention relates to recombinant bacterial outer membrane proteins comprising one or more LB1(f) peptides from surface-exposed loop 3 of MOMP P5 of non-typeable H. influenzae. Polynucleotides encoding these recombinant proteins are also covered. The invention also relates to a method of isolating the recombinant proteins and a vaccine composition for use in the treatment of Haemophilus influenzae infection.

The present invention relates to the field of vaccine formulation, particularly the field of novel adjuvant compositions comprising outer membrane vesicles (or blebs), and advantageous methods of detoxifying these compositions, and advantageous methods of use of such adjuvants.
摘要:
The present invention provides a hyperblebbing non-typeable Haemophilus influenzae bacterium which has been genetically modified by either or both processes selected from a group consisting of: down-regulation of expression of one or more tol genes; and mutation of one or more gene(s) encoding a protein comprising a peptidoglycan-associated site to attenuate the peptidoglycan-binding activity of the protein.
摘要:
The present invention relates to an immuno-protective and non-toxic Gram-negative bleb vaccine suitable for paediatric use. Examples of the Gram-negative strains from which the blebs are made are N. meningitidis, M. catarrhalis and H. influenzae. The blebs of the invention are improved by one or more genetic changes to the chromosome of the bacterium, including up-regulation of protective antigens, down-regulation of immunodominant non-protective antigens, and detoxification of the Lipid A moiety of LPS.
