Japanese scientists have discovered a naturally-occurring bacteria in a frog species with remarkably-potent anticancer activity — in fact, it destroyed cancer tumors in one dose. Led by Professor Eijiro Miyako, the team at Japan’s Advanced Institute of Science and Technology discovered that a natural bacteria from the intestines of a Japanese tree frog achieved a 100% tumor elimination rate in mice with just a single intravenous dose. Not only did the gut bacteria kill the cancer cells, it also engaged the animal’s immune system for comprehensive tumor destruction. The research team isolated a total of 45 bacterial strains from the intestines of Japanese tree frogs, fire belly newts, and grass lizards. Through systematic screening, nine strains demonstrated anti-tumor effects, with E. americana exhibiting the most exceptional therapeutic efficacy. In mice with colorectal cancer, a single intravenous administration of E. americana achieved complete tumor elimination with a 100% complete response rate — dramatically surpassing the efficacy of current standard therapies. Future research and development will expand to other cancer types, evaluating the efficacy in breast cancer, pancreatic cancer, melanoma, and other malignancies.
