Abstract
Chemical and physical studies of the
Neisseria meningitidis
group C and Y antigens indicated that these preparations are acidic polysaccharides. The group C antigen contains predominately
n
-acetyl neuraminic acid, with small amounts of glucose, glucosamine, and mannose, whereas the group Y antigen contains glucose, glucosamine, and mannose. The molecular weights of the group C and Y antigens were found to be 88,000 and 197,000, respectively. The group C antigen was susceptible to neuraminidase digestion. Finally, the immunological reactivity of neither antigen was inhibited in hemagglutination or immunodiffusion systems by neutral or substituted sugars.
