Partial overlap of anti-mycobacterial, and anti-Saccharomyces cerevisiae mannan antibodies in Crohn’s disease

Figure 7 Antibody response of mice infected with M bovis BCG. C57BL/6 mice were intravenously infected with 10⁷ viable M bovis BCG and the infection repeated after 5 wk. Serum was prepared from blood samples collected before infections, 4 wk after primary infection and 4 wk and 13 wk after secondary infection. Serum samples were tested for the presence of IgM (filled squares) and IgG (empty spheres) antibodies specific for M bovis BCG (left panel) and for S cerevisiae mannan (right panel). Results are shown as average A₄₅₀ values of 4 animals ± SE.
