Enterotoxigenic Escherichia coli (ETEC) is one of the most important pathogens of diarrhea in children under age 5 years and in travelers. A multicomponent vaccine made up of anti-colonization factor immunity plus toxoids may provide the best immune stimulation. A recombinant strain which could express bivalent antigens of CS3 fimbriae and cholera toxin B subunit (CT-B) was constructed using plasmid vector bluescript. Inoculating mice orally and immunizing rabbits intramuscularly demonstrated that the recombinant strain could induce immune response against the two antigens.
