Figure 8From: Horizontally acquired divergent O-antigen contributes to escape from cross-immunity in the classical bordetellaeImmune mediated serum killing of O1, O2 or O3 type LPS. B.bronchiseptica strains RB50 (green), 1289 (red) or MO140 (blue) were incubated with convalescent immune serum from C57/BL6 mice inoculated with 104 of O1-type LPS (A), O2-type LPS (B) or O3-type LPS (C) at the indicated serum percentages in the presence of naïve serum. Dashed line indicates 100% survival of bacteria.Back to article page
