The neutral fraction (neutral CPS‐K) of Klebsiella pneumoniae capsular polysaccharide (CPS‐K) from type 1, Kasuya strain, has already been reported as the active substance responsible for the strong adjuvant effect of CPS‐K. The present results demonstrate that neutral CPS‐K exhibits further common biological activities with lipopolysaccharide (LPS) isolated from Salmonella enteritidis . The intensity of the lethality in mice of neutral CPS‐K by the intraperitoneal route is very similar to that of LPS. Its lethality for mice by the intravenous (i.v.) route is significantly stronger than that of LPS, because the degree of increase in the sensitivity to their lethality by i.v. challenge is smaller for LPS than for neutral CPS‐K. The intensity of the pyrogenicity of neutral CPS‐K in rabbits is approximately one‐tenth of that of LPS as judged by the minimal pyrogenic doses and fever indices. The skin‐preparatory potency of neutral CPS‐K for the dermal Shwartzman phenomenon in rabbits is also approximately one‐tenth of that of LPS compared on the basis of the minimal skin‐preparatory doses. When injected i.v., neutral CPS‐K exhibits a provocative effect on hemorrhagic reactions in skin sites prepared with neutral CPS‐K or LPS.
