Figure 2. B. pseudomallei acquire less complement C3 on its surface than B. thailandensis.

Figure 2

(A) B. pseudomallei 1026b and B. thailandensis E264, or (B) B. pseudomallei DD503, B. pseudomallei ΔCPS, and B. pseudomallei ΔLPS were opsonized for 30 min at the indicated serum concentrations, washed, and stained with an anti-human C3 FITC-conjugated antibody. Samples were analyzed by flow cytometry and the data reported as mean fluorescence intensity (MFI). The bars represent the mean±SEM of three separate experiments performed with duplicate samples. (A) * indicates a statistically significant difference (P≤0.05) between B. pseudomallei and B. thailandensis values; ns  =  not significant. (B) * indicates a statistically significant difference (P≤0.05) compared to B. pseudomallei DD503 (wild-type).
