Gonococcal and meningococcal polypeptides, vaccines and diagnostics.

摘要

The subject matter of the invention is a polypeptide which includes an amino acid residue sequence constituted by at least 5 and up to about 80 amino acid residues, and which is capable of immunologically mimicking a conserved antigenic determinant site of a conococcal opacity protein (Protein II) and/or meningococcal class 5 protein. The polypeptide of the invention can be used as a vaccine or diagnostic for the prevention of gonorrhea and/or meningitidis.
