Mucosal antibody levels induced by L. lactis HA1-Fc. SIgA antibodies in the feces (A) and BALF (B) were assessed by ELISA after the chickens were vaccinated with PBS, L. lactis, L. lactis HA1, L. lactis HA1-Fc and inactivated H9N2 vaccine. The data were showed as means ± SD (n = 5). ▲▲P < 0.01 relative to PBS. **P < 0.01 relative to PBS and L. lactis. ##P < 0.01 relative to L. lactis HA1. $$P < 0.01 relative to L. lactis HA1-Fc
