Comparative study of lipopolysaccharides from Wolinella recta, W. curva, W. succinogenes and Campylobacter sputorum ssp. sputorum.
Lipopolysaccharides (LPS) were extracted from cells of Wolinella recta ATCC 33238, W. curva ATCC 33224, W. succinogenes ATCC 29543 and Campylobacter sputorum ssp. sputorum A 3563 by a hot phenol-water method and purified by nuclease treatment and by repeated ultracentrifugation. Chemical compositions of the purified LPS including fatty acid and sugar composition were examined and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was performed. All LPS preparations contained a monosaccharide identified as L-glycero-D-mannoheptose, and another heptose isomer identified as D-glycero-D-mannoheptose was a typical constituent of the LPS from all three Wolinella species.
