A recent study conducted by researchers at the Japanese Institute of Advanced Science and Technology has made a groundbreaking discovery in the field of cancer research. By isolating bacteria from the intestines of Japanese frogs, quails, and newts, the team has identified nine strains that possess a remarkable ability to destroy cancer cells. In experiments conducted on mice with colorectal cancer, a single intravenous injection of a preparation based on the Ewingella americana bacterium resulted in the complete disappearance of tumors in all animals. The bacterium actively multiplied in the tumor tissue, triggering a powerful immune response, characterized by the influx of neutrophils, T-lymphocytes, and B-lymphocytes. Future studies will aim to test this method on other types of cancer and evaluate its potential for human therapy.
