The relationship of Oxalobacter Formigenes and calcium oxalate calculi

Abstract

The intestinal Oxalobacter Formigenes were isolated in 30 cases of urolithiasis and in 45 controls. The biologic characters and morphology of the bacteria were also observed. The results showed that the colony counts in urolith group 9 (mean l0³/g. faeces) were significantly less than that of controls (mean l0⁸g. faeces) (P<0. 001). It is believed that the lesser amount of oxalobacter formigenes in urolith was the important factor of the calcium oxalate calculi formation.
