Bacterial strains are provided having at least one enhanced mechanism to sequester, bind, precipitate, chemically oxidize or reduce copper ions or other toxic divalent transition metals. The bacteria may also have optional copper resistance mechanisms. The bacteria reduce the amount of available copper to tissues, which may be cancerous tissues, and reduce tumor growth, angiogenesis and/or metastasis, or tissues subject to excess copper due to host defects in copper metabolism. The bacteria are useful for treatment of neoplastic diseases including solid tumors and lymphomas, as well as Wilson's Disease, Menke's Disease, and possible Alzheimer's Disease, Parkinson's Disease, and Creutzfeldt-Jakob Disease.
所提供的细菌菌株至少具有一种增强的机制,可固着、结合、沉淀、
化学氧化或还原
铜离子或其他有毒的二价过渡
金属。细菌还可能具有可选的抗
铜机制。这些细菌可减少组织(可能是癌组织)的可用
铜量,并减少肿瘤生长、血管生成和/或转移,或减少因宿主
铜代谢缺陷而导致
铜过量的组织。这种细菌可用于治疗肿瘤性疾病,包括实体瘤和淋巴瘤,以及威尔逊氏病、门克氏病、可能的阿尔茨海默氏病、帕
金森氏病和克雅氏病。
