Figure 1.

Serum levels of anti-Saccharomyces cerevisiae antibody (ASCA) IgA and IgG, anti-laminaribioside carbohydrate antibody (ALCA), anti-mannobioside carbohydrate antibody (AMCA), anti-chitobioside carbohydrate antibody (ACCA), anti-chitin (anti-C), anti-laminarin (anti-L), antibody against outer membrane porin C (anti-OmpC), antibody against the Pseudomonas fluorescens bacterial sequence I₂ (anti-I₂) in patients with Crohn's disease and the control. The box plots indicated the average of the serum levels and the whiskers above the box indicated the variance. ACCA = anti-chitobioside carbohydrate antibody, anti-C = anti-chitin, anti-L = anti-laminarin, ALCA = anti-laminaribioside carbohydrate antibody, AMCA = anti-mannobioside carbohydrate antibody, ASCA = anti-Saccharomyces cerevisiae antibody.
