Resum

The Edwardsiella genus presents five different pathogenic species: Edwardsiella tarda, E. anguillarum, E. piscicida, E. hoshinae and E. ictaluri. These species cause infections mainly in fish, but they can also infect reptiles, birds or humans. Lipopolysaccharide (endotoxin) plays an important role in the pathogenesis of these bacteria. For the first time, the chemical structure and genomics of the lipopolysaccharide (LPS) core oligosaccharides of E. piscicida, E. anguillarum, E. hoshinae and E. ictaluri were studied. The complete gene assignments for all core biosynthesis gene functions were acquired. The structure of core oligosaccharides was investigated by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy. The structures of E. piscicida and E. anguillarum core oligosaccharides show the presence of !3,4)-L-glycero- -D-manno-Hepp, two terminal -D-Glcp, !2,3,7)-L-glycero- -Dmanno- Hepp,!7)-L-glycero- -D-manno-Hepp, terminal -D-GlcpN, two!4)- -D-GalpA,! 3)- -DGlcpNAc, terminal -D-Galp and !5-substituted Kdo. E. hoshinare core oligosaccharide shows only one terminal -D-Glcp, and instead of terminal -D-Galp a terminal -D-GlcpNAc. E. ictaluri core oligosaccharide shows only one terminal -D-Glcp, one !4)- -D-GalpA and do not have terminal -D-GlcpN (see complementary figure).
