Clinical symptoms of mice for 14Â days after challenge. Control: The group without any treatment before infection. IgY-C: the group receiving control IgY 1Â h before inoculation. IgY-Bap: the group receiving IgY-Bap antibody 1Â h before inoculation. Control Igy-C: the group receiving only the control IgY-C antibody. No clinical sign was seen in the control IgY-C group. In the IgY-Bap group, the mean clinical symptoms after 72Â h showed a descending trend compared to the IgY-C and bacterial groups. The recovery process began with the reduction of the severity of symptoms.
