摘要: An attenuated strain of Salmonella typhimurium, designated VNP20009, was generated by deletion of the msbB and purl genes. When VNP20009 was administered intravenously (IV) to mice bearing spontaneous, syngeneic, or human xenograft tumors, the bacteria accumulated preferentially within the extracellular components of tumors, forming tumor-to-normal tissue ratios exceeding 300-1000 to 1. NVP20009 was administered safely at doses up to 2.5 x 10(9) cfu/kg in monkey toxicology studies. Based on the ...
