An immunogenic composition having 13 distinct polysaccharide-protein conjugates and optionally, an aluminum-based adjuvant, is described. Each conjugate contains a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) conjugated to a carrier protein. The immunogenic composition, formulated as a vaccine, increases coverage against pneumococcal disease in infants and young children globally, and provides coverage for serotypes 6A and 19A that is not dependent on the limitations of serogroup cross-protection.

Each conjugate contains a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) conjugated to a carrier protein. The immunogenic composition, formulated as a vaccine, increases coverage against pneumococcal disease in infants and young children globally, and provides coverage for serotypes 6A and 19A that is not dependent on the limitations of serogroup cross-protection. Methods for making an immunogenic conjugate comprising Streptococcus pneumoniae serotype 19A polysaccharide are also provided in which the serotype 19A polysaccharide is co-lyophilized with a carrier protein and conjugation is carried out in dimethyl sulfoxide (DMSO) via a reductive amination mechanism.

The invention relates to a high-efficiency 14-valent pneumococcal conjugate vaccine, which is formed by coupling and combining capsular polysaccharide extracted from fourteen types of serotype pneumococcuses and carrier protein; the fourteen types of the serotype pneumococcuses are 1, 2, 4, 5, 6A, 6B, 7F, 9N, 9V, 14, 18C, 19A, 19F and 23F; and the carrier protein is diphtherin non-toxic mutated protein CRM197, tetanus toxin protein and influenza haemophilus protein D. Compared with the prior pneumococcal conjugate vaccine, the high-efficiency 14-valent pneumococcal conjugate vaccine has the advantages that: (1) the cross-protection rate of the pneumococcuses of fourteen serotypes (1, 2, 4, 5, 6A, 6B, 7F, 9N, 9V, 14, 18C, 19A, 19F and 23F) reaches more than 90 percent; and (2) the high-efficiency 14-valent pneumococcal conjugate vaccine can generate effective protection on senior citizens which are susceptible to pneumonia and is suitable for children under two years old.

The present invention relates to new pneumococcal vaccines. The invention also relates to vaccination of subjects, in particular immunocompromised subjects, against pneumococcal infections using said novel pneumococcal vaccines.

The invention provides immunogenic compositions for mucosal delivery comprising capsular saccharides from at least two of serogroups A, C, W135 and Y of N. meningitidis. It is preferred that the capsular saccharides in the compositions of the invention are conjugated to carrier protein(s) and/or are oligosaccharides. Conjugated oligosaccharide antigens are particularly preferred. The invention also provides immunogenic compositions comprising (a) a capsular saccharide antigen from serogroup C of N. meningitidis, and (b) a chitosan adjuvant. The composition preferably comprises (c) one or more further antigens and/or (d) one or more further adjuvants. The compositions are particularly suitable for mucosal delivery, including intranasal delivery. The use of chitosan and/or detoxified ADP-ribosylating toxin adjuvants enhances anti-meningococcal mucosal immune responses and can shift the Th1/Th2 bias of the responses.

The invention discloses an enterococcus faecium EF08 as well as a feed additive and a feed containing the enterococcus faecium EF08. The enterococcus faecium EF08 is collected with the number of CGMCC (China General Microbiological Culture Collection Center) No.5549 in CGMCC. The feed additive disclosed by the invention can be used for reducing the feed excessively consumed by harmful bacteria in intestines by virtue of an equalizing effect of bacteria for equalizing the intestinal environment, furthermore, the conversion rate of the feed for economic animals is increased, the feed for the economic animals can be effectively converted into a primary animal product with an economic value, and then, the effect of increasing the economic values of the economic animals can be improved.

The invention relates to polynucleotides which are conserved or specific to one or more species of Streptococcus, Streptococcus species serotypes, and/or serotype isolates. In particular, the invention relates to polynucleotides from Streptococcus which are conserved or specific to one or more of the species of S. pneumoniae (“pneumococcus” or “S. pn.”), S. pyogenes (“group A streptococcus” or “GAS”), and S. agalactiae (“group B streptococcus” or “GBS”). The invention further relates to polynucleotides which are conserved or specific to one or more Streptococcal species serotypes, such as GBS serotypes Ia, Ib, II, III, IV, V, VI, VII, and VIII. The invention still further relates to polynucleotides which are conserved or specific to one or more clinical isolates of a Streptococcus species.

The invention relates to bacterial choline binding proteins (CBPs) which bind choline. Such proteins are particularly desirable for vaccines against appropriate strains of Gram positive bacteria, particularly streptococcus, and more particularly pneumococcus. Also provided are DNA sequences encoding the bacterial choline binding proteins or fragment thereof, antibodies to the bacterial choline binding proteins, pharmaceutical compositions comprising the bacterial choline binding proteins, antibodies to the bacterial choline binding proteins suitable for use in passive immunization, and small molecule inhibitors of choline binding protein mediated adhesion. Methods for diagnosing the presence of the bacterial choline binding protein, or of the bacteria, are also provided. In a specific embodiment, a streptococcal choline binding protein is an enolase, which demonstrates strong affinity for fibronectin.

The invention relates to a bacterial polysaccharide-protein conjugate vaccine with immunogenicity, in particular to a conjugate vaccine which is formed by connecting a recombinant rotavirus protein with a bacterial polysaccharide by using a covalent bond, a nucleotide sequence for coding the recombinant rotavirus protein, a recombinant expression system, a protein expressed by the recombinant expression system, a preparation method of the conjugate vaccine and a pneumococcus polysaccharide-recombinant rotavirus protein conjugate vaccine. The bacterial polysaccharide is connected with a recombinant rotavirus surface protein through a covalent bond. The recombinant rotavirus protein is selected from a partial or complete amino acid sequence of a P-gene rotavirus protein and a partial or complete amino acid sequence of a G-gene rotavirus protein.
