Diagrams of chromosomal mutation, plasmid maps and phenotypic feature of the sopB mutant in Salmonella Choleraesuis strains. A Chromosomal map of ΔsopB deletion mutation. B Empty plasmid vector pYA3493 and expression vector pS-SaoA. C Histopathological observations of rabbit ileal loops injected with different Salmonella Choleraesuis strains or LB control for 8 h. Bar: 50 μm. The small square showed the neutrophils in the submucosa of rabbit ileal injected with wild-type C78-3 strain. D Fluid secretion induced by Salmonella Choleraesuis strains in rabbit ileal loops. a, P < 0.05, wildtype Salmonella Choleraesuis C78-3 compared with LB, rSC0017, rSC0018(pS-SaoA), rSC0016(pS-SaoA) and rSC0011(pS-SaoA); b, P < 0.05, Salmonella Choleraesuis with ΔsopB mutation rS0017 compared to LB, rSC0018(pS-SaoA), rSC0011(pS-SaoA) and rSC0016(pS-SaoA); *P < 0.05, for the indicated strains were compared each other.
