title: Strong adjuvant action of Klebsiella O3 lipopolysaccharide and its inhibition of systemic anaphylaxis.
abstract: Immunization with lipopolysaccharide from Klebsiella O3 as an immunological adjuvant did not cause the death of mice in systemic anaphylaxis to bovine serum albumin. On the other hand, most mice immunized with lipopolysaccharide from Escherichia coli O111, Klebsiella O4 and Salmonella minnesota did die. Klebsiella O3 lipopolysaccharide enhanced IgM and IgG antibody response to BSA more markedly than Escherichia coli O111 lipopolysaccharide, while it affected the production of IgE antibody only slightly. therefore, it is suggested that the inhibition of systemic anaphylaxis by Klebsiella O3 lipopolysaccharide adjuvant might be related to its strong adjuvant action on IgM and IgG class antibody production, and that high levels of circulating IgM and IgG antibodies might act as blocking antibodies in the development of IgE-mediated systemic anaphylaxis.
