Treating Cancer With Frog Bacteria? Doctor Explains. Sources- PMID 41376334 Researchers at the Japan Advanced Institute of Science and Technology discovered that Ewingella americana, a bacterium isolated from the gut of Japanese tree frogs, exhibits extraordinary antitumor activity in mouse models. In preclinical studies of colorectal cancer, a single intravenous injection of the bacterium achieved a 100% complete response rate, entirely eradicating tumors and providing long-lasting immunity without causing detectable organ toxicity. The strain selectively targets and thrives inside the low-oxygen microenvironment of solid tumors, multiplying thousands of times within 24 hours while being rapidly cleared from healthy organs. The bacterium eliminates cancer through a powerful dual-action mechanism that combines direct cell destruction with a robust host immune response. Once inside the malignancy, E. americana secretes pore-forming cytolysins that directly breakdown cancer cells, while simultaneously releasing pro-inflammatory signals that recruit T cells, B cells, and neutrophils to the site. This intense immune recruitment completes the total destruction of the primary tumor and trains the host's immune system to resist future cancer recurrence. #science #breakthrough #cancer
