A calcified, crystalline particle smaller than 200 nanometers in diameter (the diameter of the smallest bacteria), hypothesized to be a self-replicating microorganism that can cause pathogenic calcification, as in arteriosclerosis and kidney stones.

Considerable recent attention has been focused on ultra-small microorganisms, collectively referred to by geologists and biologists as "nanobacteria" or "nannobacteria" that are involved in biomineralization.
They were: microcavities in the tissues, nannobacteria in the microcavities and around them and mineral microdeposits (irregular grains) of calcium localized in the same sites.
Our investigations on the contents of microcavities and the close surrounding tissues showed that presence of mineral microdeposits can be confronted with distribution and concentration of nannobacteria (0.15-0.20 [micro]m in diameter) within the sites.
