Abstract: Polypeptides comprising non-typeable Haemophilus influenzae (NTHi) amino acid sequences. Over 2500 specific NTHi proteins are disclosed. The invention also provides related polypeptides, nucleic acids, antibodies and methods. These can all be used in medicine for treating or preventing disease and/or infection caused by H. influenzae, such as otitis media.

Abstract: fHBP is a protein in Neisseria meningitidis. Three families of fHBP are known. To increase the ability of a fHBP protein to elicit antibodies that are cross-reactive between the families, fHBP is selected or engineered to have a sequence which can elicit broad-spectrum bactericidal anti-meningococcal antibodies after administration to a host animal.

Abstract: NadA, App and ORF40 function as adhesins in N. meningitidis. Adhesion can be modulated by targeting these three proteins. NadA allelic variants are disclosed. Autoproteolytic cleavage of App is disclosed, as is removal of the activity by mutagenesis. App is processed and secreted into culture medium when expressed in E. coli. Mature App proteins are disclosed. Knockout mutants are disclosed. Vesicles from non-Neisserial hosts with heterologous adhesin expression are disclosed.

Abstract: Meningococcal antigens are cleaved by human lactoferrin. The invention is based on the identification of the cleavage products of this reaction, and provides a method for cleaving a neisserial polypeptide, comprising the step of mixing the polypeptide with a lactoferrin enzyme. The invention also provides polypeptides obtainable by this process (i.e. the cleavage products of the lactoferrin digestion) which might be useful in the preparation of anti-meningococcal vaccines. Proteins of particular interest are meningococcal proteins 287 and App.

Abstract: Two or more Neisserial proteins (e.g. A and B) are expressed as a single hybrid protein which can be represented simply by the formula NH2-A-B—COOH.
