Abstract: The present invention relates to a novel trimeric OprF/I fusion protein comprising a portion of the Pseudomonas aeruginosa outer membrane protein F which is fused with its carboxy terminal end to a portion of the amino terminal end of the Pseudomonas aeruginosa out membrane protein I, wherein said portion of the Pseudomonas aeruginosa outer membrane protein F comprises the amino acids 190-342 of SEQ ID NO: 1 and wherein said portion of the Pseudomonas aeruginosa outer membrane protein I comprises the amino acids 21-83 of SEQ ID NO: 2, and further to a novel Opr F/I fusion protein which contains a disulphide bond pattern, preferably selected from the group consisting of (a) Cys18-Cys27-bond, (b) Cys18-Cys27-bond and Cys33-Cys47-bond, and (c) Cys18-Cys47 and Cys27-Cys33-bond, and to immunogenic variants thereof having at least 85% identity to the amino acid sequence of SEQ ID NO: 3.

Abstract: The present invention relates to an isolated nucleic acid molecule encoding an antigen, a vector comprising such nucleic acid molecule and a host cell comprising such vector. Furthermore, the invention provides antigens from Klebsiella species, fragments and variants thereof, a process for producing such antigens, and a process for producing cells expressing such antigens. Moreover, the present invention provides antibodies binding to such antigen, hybridoma cells producing such antibodies, methods for producing such antibodies, a pharmaceutical composition comprising such nucleic acid molecule, antigen, vector or antibody, the use of such nucleic acid molecule, antigen, vector or antibody for the preparation of a pharmaceutical composition, methods for identifying an antagonist capable of binding such antigen or of inhibiting the interaction activity of such antigen, methods for diagnosis or for treatment or prevention of an infection.

Abstract: The present invention relates to isolated nucleic acid molecules which encode an antigen from a nontypable Haemophilus influenzae (H. influenzae) species, a vector which comprises such nucleic acid molecule, and a host cell comprising such vector. Furthermore, the invention provides antigens from a nontypable Haemophilus influenzae species, as well as fragments and variants thereof, a process for producing such antigens, and a process for producing a cell, which expresses such antigen. More specifically such antigens are produced by or associated with bacterial infections caused by nontypable Haemophilus influenzae.
