摘要:
The present invention is drawn to attenuated Salmonella serovar strains S. Typhimurium and S. Enteritidis, conjugate vaccines derived from these attenuated strains of S. Typhimurium and S. Enteritidis, comprising an O polysaccharide covalently linked to a flagellin protein, and methods for inducing an immune response in a subject comprising administering the attenuated strains and/or the conjugate vaccines of the invention.

摘要:
Avirulent Vibrio cholerae strains of 01 (CVD111) and non-01 (CVD112 and CVD112RM) serogroups having the DNA of the cholera toxin core and the RS1 sequences of the cholera toxin locus deleted, and further having a DNA encoding a resistance to mercury, and a DNA encoding the cholera toxin B subunit, or a part thereof sufficient to confer immunogenicity, re-inserted in the chromosome. Methods of making the avirulent V. cholerae 01 and non-01 strains of the invention, and cholera vaccines using these strains.
