Recently, we reportedle3 on the basis of structural results that three types of lipopolysaccharide core occur in Citrobacter serotypes 04,027,036, and strain PCM 1487, all of them being different from E. coli core types, R,, R,, R,, and R,. The hexose-heptose regions of Citrobacter cores were descri

The genus Citrobacter consits of enteric rods that utilize citrilte as a sole carbon source. Citrobacter serotypes are normal intestinal inhabitants, but some of them have been reported in gastroenteritis and in extraintestinal infections.
The structure of Citrobacter O23-specific polysaccharide has been shown by sugar and methylation analyses of the native and chemically degraded polysaccharide and by 1H- and 13C-n.m.r. spectroscopy to consist of the tetrasaccharide repeating-units: ----4)-alpha-D-Man-(1----2)-alpha-D-Man-(1----2)-be
