Frog Gut Bacteria vs Cancer: Ewingella Americana as a Novel Nherapeutic Agent with Dual Cytotoxic and Immunomodulatory Properties

April 25th, 2026

Via: The Focal Points:

A newly published peer-reviewed study in Gut Microbes has uncovered a previously unknown cancer-fighting bacterium isolated from amphibian and reptile gut microbiomes—delivering results that exceeded modern oncology treatments.

In an immunocompetent mouse model of colorectal cancer, a single intravenous dose of Ewingella americana led to complete tumor elimination in 100% of treated animals, with no recurrence upon re-exposure to cancer cells—suggesting durable, long-term immune protection.
