The present invention relates to Neisseria ORF2086 proteins, crossreactive immunogenic proteins which can be isolated from nesserial strains or prepared recombinantly, including immunogenic portions thereof, biological equivalents thereof, antibodies that immunospecifically bind to the foregoing and nucleic acid sequences encoding each of the foregoing, as well as the use of same in immunogenic compositions that are effective against infection by Neisseria meningitidis serogroup B.
1 . A method of inducing an immune response against Neisseria meningitidis serogroup B subfamily A in a mammal comprising administering to said mammal a composition comprising an immunologically effective amount of a composition comprising at least one isolated and purified protein having greater than 95% amino acid sequence identity to the amino acid sequence of SEQ ID NO: 58.
2 . The method according to claim 1 , wherein the composition further comprises at least one protein comprising the amino acid sequence of any of even numbered SEQ ID NOS: 176-252.

4 . The method according to claim 1 , wherein the at least one isolated and purified protein has a molecular weight of 26,000 to 30,000 daltons as measured by mass spectroscopy.
5 . The method according to claim 1 , wherein the at least one isolated and purified protein has a molecular weight of 28-35 kDa as measured on a 10%-20% SDS polyacrylamide gel.
6 . The method according to claim 1 , wherein said composition further comprises a pharmaceutically acceptable buffer, diluent, adjuvant or carrier.
7 . The method according to claim 1 , wherein said composition further comprises a carrier.
8 . The method according to claim 1 , wherein said composition further an adjuvant.
9 . The method according to claim 1 , wherein said adjuvant comprises a liquid.
10 . The method according to claim 1 , wherein the at least one isolated and purified protein is a recombinant protein.
11 . The method according to claim 1 , wherein the at least one isolated and purified protein is isolated from native Neisseria species.
12 . The method according to claim 1 , wherein the at least one protein is a lipoprotein.
13 . The method according to claim 1 , wherein the at least one protein is non-lipidated.
14 . The method according to claim 1 , wherein the composition further comprises at least one additional surface antigen of Neisseria species, said additional surface antigen being a non-ORF2086 protein.
15 . The method according to claim 1 , wherein said composition further comprises a polysaccharide.
16 . The method according to claim 1 , wherein said composition comprises an additional peptide, polypeptide or protein, wherein the at least one isolated and purified protein and the additional peptide, the additional polypeptide or the additional protein form a conjugate.
17 . The method according to claim 1 , wherein the at least one isolated and purified protein comprises the amino acid sequence of SEQ ID NO: 58.
18 . A method of inducing an immune response against Neisseria meningitidis serogroup B subfamily A in a mammal comprising administering to said mammal a composition comprising an immunologically effective amount of a composition comprising at least one isolated and purified protein having greater than 95% amino acid sequence identity to the amino acid sequence of SEQ ID NO: 60.
19 . The method according to claim 18 , wherein the composition further comprises at least one protein comprising the amino acid sequence of any of even numbered SEQ ID NOS: 176-252.
20 . The method according to claim 18 , wherein the at least one isolated and purified protein is nonpathogenic.
21 . The method according to claim 18 , wherein the at least one isolated and purified protein has a molecular weight of 26,000 to 30,000 daltons as measured by mass spectroscopy.
22 . The method according to claim 18 , wherein the at least one isolated and purified protein has a molecular weight of 28-35 kDa as measured on a 10%-20% SDS polyacrylamide gel.
23 . The method according to claim 18 , wherein said composition further comprises a pharmaceutically acceptable buffer, diluent, adjuvant or carrier.
24 . The method according to claim 18 , wherein said composition further comprises a carrier.
25 . The method according to claim 18 , wherein said composition further an adjuvant.
26 . The method according to claim 18 , wherein said adjuvant comprises a liquid.
27 . The method according to claim 18 , wherein the at least one isolated and purified protein is a recombinant protein.
