Lipopolysaccharide Engineering in Neisseria meningitidis

Structure of the L5 lipopolysaccharide core oligosaccharides of Neisseria meningitidis.

Three different oligosaccharides were isolated by mild acid hydrolysis of the lipopolysaccharides, obtained from Neisseria meningitidis serotype 5, and their structures were elucidated by combined chemical and physical techniques. The use of 500-MHz 1H NMR in both one-dimensional and two-dimensional modes as well as nuclear Overhauser effect experiments were employed. To assist in the structura...

Lipopolysaccharide serotyping of Neisseria meningitidis by hemagglutination inhibition.

The method of hemagglutination inhibition was used to investigate the antigenic diversity of lipopolysaccharide (LPS) from Neisseria meningitidis and to develop a serotyping systems based on this antigen. The system uses outer membrane complex prepared by a simple extraction procedure to inhibit homologous hemagglutination reactions involving sheep erythrocytes sensitized with purified LPS and ...

Neisseria meningitidis W135, Turkey

We describe the first case of Neisseria meningitidis W135 meningitis in Turkey. The strain was genotypically unrelated to the clone (W)ET-37, isolated from Hajj pilgrims in 2000.

Microaerobic denitrification in Neisseria meningitidis.

The major aetiological agent of human bacterial meningitis is Neisseria meningitidis. During the course of disease and host colonization, the bacterium has to withstand limited oxygen availability. Nitrogen oxide and nitrogen oxyanions are thought to be present, which may constitute an alternative sink for electrons from the N. meningitidis respiratory chain. A partial denitrification pathway i...
