In 2004 a Mayo Clinic team led by Franklin Cockerill, John Lieske, and Virginia M. Miller, reported to have isolated nanobacteria from diseased human arteries and kidney stones. Their results were published in 2004 and 2006 respectively.[3][13] Similar findings were obtained in 2005 by László Puskás at the DNA Lab, University of Szeged, Hungary. Dr. Puskás identified these particles in cultures obtained from human atherosclerotic aortic walls and blood samples of atherosclerotic patients but the group was unable to detect DNA in these samples.[14]
