CHEMICAL COMPOSITION OF ENDOTOXIN FROM ORALVEILLONELLA

Abstract
Lipopolysaccharide (LPS) has been prepared from four human oral strains ofVeillonellaby phenol‐water extraction of acetone‐washed whole cells. LPS from all strains contained 2‐keto‐3‐deoxy‐octonate (KDO), heptose, glucose, glucosamine and galactosamine. In addition, galactose was present in one strain, and galactose and ribose in another. The preparations were rich in lipid and KDO.
