Introduction: Nanobacteria (calcifying nanoparticles, nanobes) are one of the most controversial issues in contemporary biology. Studies show accumulating evidence on association of nanobacteria with pathologic calcifications such as kidney stone, arterial plaque, calcification of coronary arteries, and cardiac valves calculus. The Hypothesis: Nanobacteria can tolerate harsh conditions extremely well. The apatite mineral layer around the organism and slow metabolism is likely to be the reason for the resistance of nanobacteria. They showed a wide resistance to the several disinfecting and sterilizating chemicals as well as autoclaving, ultraviolet light, microwaves, heating and drying treatments. Hence, it seems logic to postulate that hazardous diseases can be easily transmitted via nanobacterial contamination of medical and dental equipment. Evaluation of the Hypothesis: It is not enough to claim an agent not living according to the standard view on living creatures, as irrelevant to biological safety of cell cultures, or to human and animal health. Although the nature of prions is still under debate and prions are classified as nonliving, they exist and cause diseases, and thus form a serious risk for animal and human health. The risk was recognized only after enormous economical losses. It appears that nanobacteria situation is rather similar, except the fact that nanobacteria appear to cause or contribute to common hazardous diseases of the mankind. Hence, world-widely well-known organizations such as the Centers for Disease Control and Prevention, the Occupational Safety and Health Administration, and the World Health Organization should pay more attention to transmission of hazardous diseases via nanobacterial contamination of medical and dental equipment.
