Vaccination against meningococcus, a bacterium with five chemically different capsular polysaccharides known as serogroup A, B, C, Y and W135, also follows a similar paradigm. When the first ...

Vaccines using the immune response to the capsular polysaccharide provide effective, serogroup-specific protection against invasive disease. Vaccines based on the plain polysaccharide of the ...

The so-called capsular polymerases, which produce the different polysaccharide capsules, also play an important role in the formation of the chain. "The polymerase recognizes the linker and can ...

pneumoniae express either the O1 or O2 antigen. In addition to the O-type, the type of polysaccharide capsule present on the surface of K. pneumoniae can also provide important insights into the ...
