Fig. 1From: Prime-boost vaccination with attenuated Salmonella Typhimurium ΔznuABC and inactivated Salmonella Choleraesuis is protective against Salmonella Choleraesuis challenge infection in pigletsAttenuated S. Typhimurium ΔznuABC is not detectable from day 18 after vaccination. In a, symbols depict the mean concentration of S. Typhimurium ΔznuABC (expressed as LOG10 CFU/g) in group A at different time points (day 1, 5, 13, 18, 33 after vaccination). Bars represent the standard deviation. In b, columns represent the percentage of shedder piglets of group A at different time-points. S. Typhimurium ΔznuABC is not detectable from day 18 after vaccination. Group B and C are not shown because negative. Depicted microbiological results derived from the semi-quantitative approachBack to article page
