Infection by Enterotoxigenic Escherichia coli is a common cause of diarrhea in animals. The development of vaccines against enterotoxins can effectively control the infection. We have previously constructed a recombinant antigen SLS fused by STa, LTB and STb enterotoxin and it showed a high immunogenicity in mice. Herein, we evaluated the expression of SLS in three different E. coli cells with corresponding plasmids. SLS proteins expressed in E. coli BL21 (DE3) and Rosetta-gami B (DE3) were aggregated as inclusion bodies, and the proteins solubility were no
