Abstract:
In this study, biological activities of the lipopolysaccharide (LPS) extracted from Bacteroides fraglis NCTC 9343 were measured in animals. The results showed that LPS expressed typical endotoxicities, e.g. pyrogenicity in rabbits, lethality in mice and chick embryoes, ability to induce local Shwartzman reaction and coagulability for limulus emoebcyte lysate. But its biological activities were lower compared with that of Enterobacteriaceae. It is suggested that the weaker biological activities are related to the unusual chemical structure of the LPS.
