Abstract: The present invention is directed to monoclonal antibodies and antigen-binding portions thereof, specific for the capsular polysaccharides of Neisseria meningitidis serogroup X (NmX), wherein said antibodies or portions thereof are characterized by the sequences of the 6 CDR of the variable regions of the heavy and light chains. These antibodies are suitable for in vitro detection of Neisseria meningitidis serogroup X especially in a biological sample without purification of the capsular polysaccharides. The invention also concerns said monoclonal antibodiesor adequate portions thereofin different diagnostic tests and methods, in order to detect NmX. The invention discloses also a rapid diagnostic test for detecting NmX in a biological fluid.

Abstract: A method for immunizing a subject against serogroup X meningococcus by administering a vaccine comprising one, two or all three of: (i) a meningococcal fHbp antigen; (ii) a meningococcal NHBA antigen; and/or (iii) a meningococcal NadA antigen. The vaccine may also include meningococcal outer membrane vesicles.

Abstract: The present invention is drawn to a penicillin-binding protein expressed by Neisseria meningitidis, or a fragment, or a variant, or a variant fragment thereof, or nucleic acids encoding them, or antibodies or antibody fragments directed against them, as medicaments or in pharmaceutical compositions. The invention is also directed to the use of penicillin-binding proteins expressed by Neisseria meningitidis, or nucleic acids encoding them, or antibodies directed against them for the prophylactic and/or therapeutic immunotherapy of mammals, preferably human beings, against infection by Neisseria meningitidis and/or by a bacterial strain expressing a variant of a Neisseria meningitidis penicillin-binding protein.
