So, if you don't know about it -- she eats you whatever.
It's rather new form of Ca-based life, that lives in your blood vessels and using your calcium for life and building their homes. You can google for it -- it's true kind of life, no tricks. And nanobacteria can resist high doses of radiation. Also: EDTA unroofs nanobacteria and tetracycline kills them. Thats all you need to know :)
