Determination of the antibody responses elicited by L. lactis/pNZ8148-Spax-HA in chickens. Sera, feces and intestine washes were collected from chickens vaccinated orally with PBS, L. lactis/pNZ8148-Spax or L. lactis/pNZ8148-Spax-HA. a HA-specific IgY antibody responses in sera. b HA-specific sIgA antibody responses in the intestine washes. c HA-specific sIgA antibody responses in the feces. d Neutralizing antibody titres. The data are represented as the means ± SDs, and the asterisks indicate significant differences compared with the PBS- and L. lactis/pNZ8148-Spax-vaccinated controls (p ˂ 0.05)
