Calcium Phosphate Mineralization of Bacteria

The present work deals with the investigation of mineralization of coccus bacteria infecting human organism, for the Staphylococcus aureus colony as example. The structure and morphology in calcified heard valves and their bioprostheses were investigated.Infectious (septic) endocarditis is characteristic of all the heart valves of this series. About 50 samples of heart valves and their bioprostheses (porcine) subjected to calcium phosphate mineralization were studied. In addition, for more details, we carried out modeling of the ion composition of blood plasma with respect to major elements with the microbial culture of Staphylococcus aureus. In the experiments, a colony of bacteria on solid agar was placed in the aqueous solution with ion concentrations Са = 1.33 mM; Р = 1.5 mM; Mg = 1 mM; NaCl = 0.15 M. The composition of the solution corresponded to the concentrations of ionized elements in the blood of a healthy adult person. The colony of bacteria was in the upper part of the solution.
