Specific secretory immunoglobulin (Ig) levels. The piglets received pPG-COE-DCpep/L393 (1010 CFU in 1 mL of phosphate-buffered saline (PBS) and PBS alone) for the different vaccination programs, via an oral route; Group A (1 mL pPG-COE-DCpep/L393/Day 0); Group B (2 mL pPG-COE-DCpep/L393/Day 0); Group C (2 mL pPG-COE-DCpep/L393/Day 2); Group D (4 mL pPG-COE-DCpep/L393/Day 2); Group E (1 mL PBS). (A) Mucus extracts were collected using rectal swabs from the groups administered with pPG-COE-DCpep/L393 on days 3, 5, 7, 9, and 11 post-vaccination. The results represent the IgA titer ± standard errors of the means in each group. Serum was collected from the groups administered with pPG-COE-DCpep/L393 on days 3, 5, 7, 9, and 11 post-vaccination. The results represent the IgG titer ± standard errors of the means in each group. (B) The immune effects of pPG-COE-DCpep/L393, pPG/L393, and PBS. The piglets received 2 mL pPG-COE-DCpep/L393, pPG/L393 (1010 CFU in 1 mL of PBS), and PBS alone, for the different vaccination programs via an oral route. Mucus extracts were collected using rectal swabs from different groups on five days post-vaccination. The results represent the IgA titer ± standard errors of the means in each group. Serum was collected from the groups administered pPG-COE-DCpep/L393 five days post-vaccination.
