Figure 3From: Presumable role of outer membrane proteins of Salmonella containing sialylated lipopolysaccharides serovar Ngozi, sv. Isaszeg and subspecies arizonae in determining susceptibility to human serumC3 complement protein depositions on the bacterial cells. Indirect enzyme-linked immunosorbent assay (ELISA). Bacterial cells in log-phase (1 × 107 CFU/ml) were incubated in 50% HS, 50% HS-IN (control 1) or PBS (control 2) for 30 min at 37°C. Activation of C3 differs significantly if the p values are less than 0.005 (*).Back to article page
