title: The toxicity of Bacteroides thetaiotaomicron cell-surface antigens to chicken embryos.
abstract: The toxicity of B. thetaiotaomicron lipopolysaccharides and capsular antigen to 11-day-old chicken embryos was examined. CELD50 (chicken embryo LD50) of these preparations were determined. All examined preparations showed the lethal activity for chicken embryos. The toxicity of lipopolysaccharides was much higher than the toxicity of capsular antigen.
