To construct a novel live oral vaccine candidate for the prevention of pathogenic Escherichia coli infections in neonatal piglets, an expression and secretion plasmid and an attenuated Salmonella delivery system were used. The individual E. coli genes K88ac, K99, FasA, F41 and intimin adhesins were inserted into pBP244 containing asd, lepB, secA and secB, and these plasmids were transformed into a Salmonella Typhimurium ΔcpxR Δlon Δasd. Forty female BALB/c mice were divided into four groups, A… CONTINUE READING
