Very cool research. They just injected mice with 45 different bacterial strains, and then isolated and cultivated the ones that had the best performance. It seems that it might be quite easy to cultivate these strains to target different tumors / specific tumor samples.

Ewingella Americana itself is a quite common bacterial species, but it seems that the effective strain is the frog-derived and cultivated one. So don't go injecting yourself with a random E. Americana.
