The present study was investigated the antibacterial effect of several sodium salts and the sodium salt mixture composed with sodium chlorate, sodium azide and sodium cyanide on Salmonella gallinarum (S. gallinarum) infection in murine derived macrophage RAW 264.7 cells. In the infection assay of S. gallinarum in macrophage cells pretreated with 15 mM sodium chlorate, 0.3 mM sodium cyanide, 0.3 mM sodium azide and the sodium salt mixture (15 mM sodium chlorate, 0.3 mM sodium cyanide, 0.3 mM sodium azide), respectively, the numbers of S. gallinarum in all treated-groups tended to decrease in the process of time after treatment, but the group treated with sodium cyanide was no significant difference compared with control. After 24 hours of treatment, the number of S. gallinarum in sodium azide (p<0.05), sodium chlorate (p<0.001) and the sodium salt mixture (p<0.001) treated-group was significantly decreased compared with control, and that in the sodium salt mixture treated-group was decreased the higher than all groups. The results of this study demonstrated that the sodium salt mixture composed with sodium chlorate, sodium azide and sodium cyanide, has the antimicrobial activity for S. gallinarum and may be beneficial on the control of intracellular pathogens.
