[The heptose region of lipopolysaccharides of Pasteurella multocida]

The heptose region of the lipopolysaccharides (LPS) of Pasteurella multocida consists of the trisaccharide L Hep 1----2 L Hep 1----3 L Hep or L Hep 1----3 L Hep 1----2 L Hep. This trisaccharide and the oligosaccharide consisting of 3 moles heptose and 1 mole glucose were isolated from the LPS of the strain D 33. The data suggest that the LPS biosynthesis of P. multocida is different from that of Salmonella spp.
