A frog-gut microbe wiped out tumors in every treated mouse; read the fine print (thefocalpoints.com)
Underneath a sensational blog post sits a real paper in Gut Microbes. A strain of Ewingella americana from amphibian guts, given as one IV dose, homes to a tumor's low-oxygen core, multiplies fast, and recruits T cells and neutrophils; in mice it cleared colorectal tumors and beat both chemo and a checkpoint drug.
The flip: the outlet is a McCullough Foundation blog readers call a crank source, the injected tumors were small and tracked for only two weeks, and curing mice is the routine entry ticket that few therapies survive in humans.
