Abstract
The toxicity of purified lipopolysaccharides (LPS) and capsular polysa ccharides (CPS) extracted from 3 strains of Bacteroides vulgatus to 11 day old chicken embryos was examined. The three B. vulgatus strains w ere isolated from different sources. The CELD50 (chicken embroys letha l dose 50%) of these preparations was determined. All antigens were sh own to be lethal to chick embroys. The toxicity of LPS of the strains isolated from clinical sources was higher than that of the capsular an tigens. The LPS and CPS of one strain isolated from normal gut-flora w as less toxic than other antigens.
