Phagocytosis and bactericidal activity of the macrophages modulated by the anti-rOmpF sera in vitro. A Effect of the anti-rOmpF sera on opsonophagocylic killing of E. coli by murine macrophages. Data are expressed as percentage (mean ± SD) of killed bacteria; B bactericidal activity of serum complement on E. coli. Escherichia coli CVCC 1515 was incubated for 1 h with the anti-rOmpF sera and complement (or heat-inactivated complement) (the rOmpF+ adjuvant group), the anti-PBS sera and complement (or heat-inactivated complement) (the PBS+ adjuvant group), and PBS and complement (or heat-inactivated complement) (the negative control group), respectively. Viable bacteria were counted, and data are expressed as mean ± SD. Lower case letters indicate a significant difference between two groups (p < 0.05)
