JOL2077 vaccine induced efficient SG-specific systemic IgG and mucosal IgA responses. Chickens (N = 10) were vaccinated with sterile PBS, JOL2068 or JOL2077, and serum and intestinal wash samples were analysed for ompA SG-specific IgG and sIgA levels, respectively, by an indirect ELISA. A Serum IgG. B Intestinal sIgA responses. Each data point represents mean ± SD of six chickens. *p < 0.05. ns: non-significant.
