Salmonella Typhimurium wild type and ΔpurA::kanR colonization of pigs.

Colonization of Salmonella Typhimurium WT and ΔpurA::kanR strains in 6 piglets 8 days post oral inoculation with 2×107 colony forming units (CFU) of both strains. The log10 CFU of the wild type and ΔpurA per gram sample is given as the mean ± standard deviation (SD). The frequency shows the fraction of positive samples in relation to the total number of tissue samples (n = 6). An asterisk (*) indicates a statistically significant difference (p≤0.05) between the log10(WT/ΔpurA::kanR) in the inoculum and the log10(WT/ΔpurA::kanR) in the respective sample.
