Kidney Stones and Nanobacteria

It appears that infections may be a major cause of kidney stones. In 1996, researchers from Turkey (1) and Finland (2) reported that newly discovered bacteria called nanobacteria, cause kidney stones. Researchers in Formosa have reported finding a common intestinal bacteria called proteus and another often sexually transmitted bacteria called ureaplasma in kidney stones (3).

Doctors used to tell their patients with kidney stones to reduce their intake of calcium, but recent research shows that restricting calcium causes stone formers to increase their chances of getting kidney stones (4,5) and osteoporosis (6). Doctors failed to find infections in kidney stones before because nanobacteria are so small that they cannot be seen by conventional microscopes, but can be seen through the super powerful electron microscope. They do not stain with conventional bacterial stains, they do not grow in conventional laboratory agar and they grow very slowly on special media. Nanobacteria cause calcium, phosphorus and other minerals to form carbonate apatite as a shell around them, that is a major component of kidney stones. Antibodies that bind to nanobacteria were found in all 30 stones tested. Tetracycline antibiotics accumulate in the calcium shell, and have been shown to kill nanobacteria. There are no studies to test whether daily intake of doxycycline could prevent kidney stones, but these tests should be started soon. Treatment of kidney stones with antibiotics is controversial and not accepted by most doctors. Discuss this with your doctor or any new findings on avoiding kidney stones.
