Fig. 5From: The impact of sseK2 deletion on Salmonella enterica serovar typhimurium virulence in vivo and in vitroIntracellular proliferation of the WT, ΔsseK2, and its complemented strains in J774A.1. cells. The WT, ΔsseK2, and complemented strains were co-incubated with J774A.1. cells, and the number of bacteria was counted at 1, 3.5 and 23.5 h. The asterisk (*) indicates that there was a statistically significant difference between the WT, ΔsseK2 and complemented strains at 3.5 h compared with 1 h. (P < 0.05)Back to article page
