Scientists discover an amphibian gut bacterium 100% effective in destroying cancer cells in rats

Japanese scientists discovered that Ewingella americana, a bacterium from tree frog intestines, completely eliminated colorectal cancer tumors in lab mice with 100% effectiveness, outperforming existing treatments like chemotherapy. The bacterium works by accumulating in oxygen-deprived cancer cells and triggering targeted immune responses while leaving healthy tissue unharmed. Researchers are now developing this promising natural cancer therapy and studying its potential against other cancer types.
