The original publication of the article contained errors in the labels of significant differences among groups in Figs. 4b and 5b.

Fig. 4

Effects of differential doses of bacteria on CaOx crystal growth and aggregation. CaOx crystals were generated in the absence (blank control) or presence of 10–105 CFUs/ml of E. coli. The crystal area (a) and number of crystal aggregates (b) were then analyzed. Each bar was derived from three independent experiments and the data are reported as mean ± SEM

Effects of viability of bacteria on CaOx crystal growth and aggregation. CaOx crystals were generated in the absence (blank control) or presence of 105 CFUs/ml of intact viable, intact dead or fragmented E. coli. The crystal area (a) and number of crystal aggregates (b) were then analyzed. Each bar was derived from three independent experiments and the data are reported as mean ± SEM
