Aromatic-dependent salmonella as anti-bacterial vaccines and as presenters of heterologous antigens or of DNA encoding them.

Author information

Department of Microbiology and Immunology, Stanford University School of Medicine, Stanford, CA 94305, USA.


The development of live bacterial vaccines is reviewed, in particular aromatic-dependent Salmonella, either for protection against the corresponding infections (including typhoid fever) or as carrier-presenter of antigens of unrelated pathogens or of DNA specifying them. Aromatic-dependent Salmonella live vaccines are also compared with BCG and Ty21a and the recent records of exceptional situations are discussed in which aroA (deletion) strains of Salmonella typhimurium cause progressive disease in mice.
