N-propionylated group B meningococcal polysaccharide mimics a unique epitope on group B Neisseria meningitidis
Antibodies induced in mice by the N-propionyl (N-Pr)-group B meningococcal polysaccharide (GBMP)-tetanus toxoid (TT) conjugate were bactericidal for GBM organisms independent of protein serotype. The antisera contained two populations of N-Pr-GBMP-specific antibodies, only one of which crossreacted with the GBMP. Particularly significant was the fact that the bactericidal activity was mainly as...
متن کاملPhysicochemical properties of Neisseria meningitidis group X polysaccharide antigen.
Neisseria meningitidis group X occurs in human carrier populations and is rarely implicated in serious disease. This organism possesses a capsular group antigen which is an acidic polysaccharide. It is composed of the amino sugars, glucosamine, glucosamine-6-phosphate, galactosamine, and the simple hexose, glucose. The group X capsular antigen has an S(20,w) (0) of 3.6, and the acidic nature of...
متن کاملHighly Conserved Neisseria meningitidis Surface Protein Confers Protection against Experimental Infection
A new surface protein, named NspA, which is distinct from the previously described Neisseria meningitidis outer membrane proteins was identified. An NspA-specific mAb, named Me-1, reacted with 99% of the meningococcal strains tested indicating that the epitope recognized by this particular mAb is widely distributed and highly conserved. Western immunoblotting experiments indicated that mAb Me-1...
متن کاملMonoclonal antibodies specific for Neisseria meningitidis group B polysaccharide and their peptide mimotopes.
From five mice immunized with Escherichia coli K1 bacteria, we produced 12 immunoglobulin M hybridomas secreting monoclonal antibodies (MAbs) that bind to Neisseria meningitidis group B (NMGB). The 12 MAbs also bound the capsular polysaccharide (PS) of E. coli K1 [which, like NMGB, is alpha(2-8)-linked polysialic acid (PSA)] and bound to EV36, a nonpathogenic E. coli K-12 strain producing alpha...
متن کاملAn Outer Membrane Protein of Neisseria Meningitidis Group B Responsible for Serotype Specificity
Meningococcal groups B and C have been subdivided into a series of serotypes based upon the antigenic specificity of protein serotype antigens (STA). The purpose of these studies was to obtain the STA by gentle methods and determine its anatomic location in the meningococcal cell. The STA was extracted from group B meningococcal strains by either 0.2 M LiCl or 0.2 M CaCl(2) and isolated from th...
