Immunogenicity of Hemolysin, Protease and Lipopolysaccharide Extracted from Aeromonas hydrophila in Common Carp (Cyprinus carpio L.).

Peptide adjacent to glycosylation sites impacts immunogenicity of glycoconjugate vaccine

Glycoconjugate vaccine is composed of polysaccharides (PSs) covalently linked with carrier protein. Glycosylation site selection, as a significant factor leading to heterogeneities of glycoconjugate structure, draws more and more attentions for its impact on the immunogenicity of glycoconjugate vaccine. To elucidate the relationship between glycosylation connectivity and immunogenicity of glyco...

Preparation and characterization of detoxified lipopolysaccharide-protein conjugates.

Alkaline treatment of Pseudomonas aeruginosa type 5 lipopolysaccharide (LPS) resulted in reduced toxicity as measured by both the Limulus amoebocyte assay and the rabbit pyrogenicity test. Chemical analysis of the deacylated LPS (D-LPS) revealed that ester-linked fatty acids were removed while the amide-linked fatty acids remained intact. The neutral and amino sugar compositions for native LPS ...

Immunogenicity of a tetravalent meningococcal glycoconjugate vaccine in infants: a randomized controlled trial.

CONTEXT Immunization with a meningococcal tetravalent (serogroup ACWY) glycoconjugate vaccine is recommended for all US adolescents. However, the currently licensed vaccine is poorly immunogenic in infancy, when the highest rates of disease are observed. OBJECTIVE To determine the immunogenicity of a novel tetravalent CRM(197)-conjugated meningococcal vaccine (MenACWY) in infants. DESIGN, S...

Immunogenicity of a Bivalent Adjuvanted Glycoconjugate Vaccine against Salmonella Typhimurium and Salmonella Enteritidis

Salmonella enterica serovars Typhimurium and Enteritidis are the predominant causes of invasive non-typhoidal Salmonella (iNTS) disease. Considering the co-endemicity of S. Typhimurium and S. Enteritidis, a bivalent vaccine formulation against both pathogens is necessary for protection against iNTS disease, thus investigation of glycoconjugate combination is required. In the present work, we in...
