The present invention provides a real-time PCR method that allows in a single step the simultaneous detection of etiological agents of bacterial meningitis, more specifically, Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae. For this, primers were used to amplify particular regions of the genomes of said bacteria. The presence of bacteria in a sample is indicated by the presence of amplicon, which is detected by means of detection methods appropriate to the PCR methodology employed.

Multivalent meningococcal conjugate vaccines are administered according to a schedule in which a first dose is administered to a patient aged between 0 and 12 months, and a second dose is administered to the patient aged between 12 and 24 months.

The present invention relates to a novel use of a bacterial secretome in the field of the treatment of skin lesions and more particularly of wound healing. The invention also relates to cosmetic or dermatological compositions comprising such a bacterial secretome as active agent.

Multivalent meningococcal conjugate vaccines are administered according to a schedule in which a first dose is administered to a patient aged between 0 and 12 months, and a second dose is administered to the patient aged between 12 and 24 months.

Provided herein is an animal model system and uses thereof. In particular, provided herein is an animal model for Neisseria infection and use of such a model in research and screening applications.

The present invention relates to the field of recombinant production of biological molecules in genetically modified cells. More particularly, it relates to a method for recombinant production of sialylated human milk oligosaccharides (HMO) using a genetically modified cell expressing a protein of the major facilitator superfamily (MFS), the protein expressed being Fred.

The present invention relates to the fields of sexually transmitted disease and immunology. More specifically, but not exclusively, the invention provides a composition and methods to prepare and administer a vaccine for Neisseria gonorrhoede and/or other gram-negative bacteria such as by using psoralen-inactivated bacteria.

The present invention relates to neisserial LPS having a hexa-acylated lipid A moiety, wherein the hexa-acylated lipid A moiety is modified as compared to the lipid A moiety of a wild-type neisserial LPS in that it comprises a palmitoleoyl instead of a lauroyl secondary acyl chain on the glucosamine at the non-reducing end of the lipid A moiety. The invention further relates to mixtures of the hexa-acylated LPS with the corresponding penta-acylated LPS, lacking a secondary acyl chain on the glucosamine at the non-reducing end of the lipid A moiety. The invention also relates to neisserial bacteria that have been genetically modified to reduce expression of the endogenous lpxL1 gene and to introduce expression of a heterologous thermosensitive lpxP gene for producing the hexa- and penta-acylated LPS. By selecting the time and/or temperature at which the bacterium is grown, it is feasible to increase or decrease the amount of hexa-acylated lipid A structure relative to the corresponding penta-acylated structure and thereby modulate the TLR4 agonist activity of the neisserial LPS of the invention, to the exact level of activity required for a particular immunotherapeutic approach.

The present disclosure relates to an immunogenic composition comprising a combination of meningococcal antigens which comprises at least one factor H binding protein (fHBP) A protein, at least one fHBP B protein, at least one Neisseria adhesin A (NadA) protein, and at least one detergent-extracted Outer Membrane Vesicle (dOMV). The meningococcal antigens may be from a Neisseria meningitidis serogroup B. The combination of antigens provided a broad coverage of bacteria strains. Further, the present disclosure relates to the use of the immunogenic composition in methods for eliciting an immune response.

The present invention relates to a novel process for purifying bacterial polysaccharide. It is an efficient and scalable process for removing impurities from Neisseria meningitidis serogroup C (Men-C) polysaccharide which is capable of being used as such in a derivatized form or linked to other molecules, for the preparation of vaccines, more particularly conjugate vaccines for N. meningitidis infection.
