摘要

Tumor targeting Salmonella typhimurium has been developed. These bacteria were mutagenized and a strain auxotrophic for leucine and arguine was selected. This strain was also engineered to express GFP. This train, termed A1, could target prostate tumors in nude mouse models and inhibit their growth. A1 was passaged through a tumor and re-isolated and termed A1-R. A1-R had greater antitumor efficacy and could cure breast, prostate, pancreatic, and lung tumors in nude mouse models.
