Antibody responses induced by the Δcrp mutant in ducks. Ducks were intranasally immunized twice with the Δcrp mutant at an interval of 10 days. The serum IgY responses specific to whole bacterial antigen (a) and OMPs (b) and the bile IgA responses specific to whole bacterial antigen (c) and OMPs (d) were then assessed 3 days before immunization and 20 days post-immunization via indirect ELISA. The data are expressed as the means ± SD and were analyzed at significance levels of 0.05 (*) and 0.01 (**)
