Abstract
Several species of bacteria formed an intracellular crystalline material when grown in urine obtained from a subject with a history of infrequent renal calculi formation. The species Proteus mirabilis, P. rettgeri, Providencia stuartii, Enterobacter aerogenes, E. cloacae, Escherichia coli and Candida albicans formed crystals of hydroxyapatite. Klebsiella pneumoniae, Pseudomonas aeruginosa and P. vulgaris produced crystals of calcite -III. Several of these bacteria were isolated from the kidneys of patients with renal calculi, indicating that microorganisms may be involved in the nucleation process during calculogenesis.
