Investigation of humoral immunity after vaccination with different formulations. A The study investigates the presence of Omp10-specific mucosal total IgG antibodies in mice. The sample was collected from mice after oral vaccination with several vaccine groups. B After a period of 30 days after the administration of the last vaccine, BALB/c mice demonstrate a humoral immune response. Serum dilutions of Omp10-specific IgG1 from different groups of mice were prepared at a ratio of 1:200. C The presence of Omp10-specific mucosal secretory IgA (sIgA) antibodies was detected in fecal pellets. Data are presented as mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
