a After incubating the MEAS 1 and MEAS 3 immune serum with HN105, WUSS147, and CZ130302, fresh swine blood was added. The live bacterial count was recorded at 1, 2, 4, and 6 h, calculated the survival rate and drew the survival curve. b The three MEAS immunized sera were incubated with HN105, WUSS147, and CZ130302, then added to RAW246.7 cells and incubated. The number of viable bacteria was counted at 0 h, and the phagocytosis rate was calculated. c From the time of phagocytosis, the number of viable bacteria was counted after 1, 2, and 3 h, and the survival rate was calculated, drew the survival curve. Significance (P)-value summary analysed by Unpaired two-tailed Student’s t-test (*P < 0.05, **P < 0.01, ***P < 0.001, ns no significance).
