Abstract: In one aspect, the invention relates to an immunogenic composition that includes a Clostridium difficile toxoid A and/or a C. difficile toxoid B, and methods of use thereof. In another aspect, the invention relates to a method for eliciting an immune response in a human against a C. difficile infection. The method includes administering to the human an effective dose of a composition, which includes a C. difficile toxoid, wherein the composition is administered at least two times, wherein the second administration is about 30 days after the first administration, and wherein the immune response against C. difficile toxin A and/or toxin B is sustained.

Abstract: The present invention relates to new immunogenic compositions comprising conjugated Streptococcus pneumoniae capsular saccharide antigens (glycoconjugates) and uses thereof. Immunogenic compositions of the present invention will typically comprise at least one glycoconjugate from a S. pneumoniae serotype not found in Prevnar, Synflorix and/or Prevnar 13. The invention also relates to vaccination of human subjects, in particular infants and elderly, against pneumoccocal infections using said novel immunogenic compositions.

Abstract: The invention relates to immunogenic polysaccharide-protein conjugates comprising a capsular polysaccharide (CP) from Streptococcus agalactiae, commonly referred to as group B streptococcus (GBS), and a carrier protein, wherein the CP is selected from the group consisting of serotypes Ia, Ib, II, III, IV, V, VI, VII, VIII, and IX, and wherein the CP has a sialic acid level of greater than about 60%. The invention also relates to methods of making the conjugates and immunogenic compositions comprising the conjugates. The invention also relates to immunogenic compositions comprising polysaccharide-protein conjugates, wherein the conjugates comprise a CP from GBS serotype IV and at least one additional serotype. The invention further relates to methods for inducing an immune response in subjects against GBS and/or for reducing or preventing invasive GBS disease in subjects using the compositions disclosed herein. The resulting antibodies can be used to treat or prevent GBS infection via passive immunotherapy.

Abstract: NEW MATERIAL: Recombinant plasmid pTPGIF2 having a size of 4,660 base pairs and a structure obtained by inserting a DNA having a size of 52 base pairs and containing a sequence coding somatostatin into a BamHI incision site of a plasmid vector pTP70-1 capable or fusing a heteropeptide to a carboxy-terminal of a dihydrofolic acid reductase gene of E. coli. USE: Producton of fused protein containing somatostatin.
PREPARATION: A somatostatin gene is integrated into a plasmid vector pTP70-1. pTPGIF2 is kept in stable state when introduced into E. coli. C600 strain. The E. coli. C600 train containing pTPGIF2 is deposited in Fermentation Research institute as FERM BP-1577.-
