Effect of Curcumin Against Proteus mirabilis During Crystallization of Struvite from Artificial Urine

Abstract EN

We investigated the activity of curcumin against Proteus mirabilis and the struvite crystallization in relation to urinary stones formation.

In order to evaluate an activity of curcumin we performed an in vitro experiment of struvite growth from artificial urine.

The crystallization process was induced by Proteus mirabilis to mimic the real urinary tract infection, which usually leads to urinary stone formation.

The results demonstrate that curcumin exhibits the effect against Proteus mirabilis inhibiting the activity of urease—an enzyme produced by these microorganisms.

Addition of curcumin increases the induction time and decreases the efficiency of growth of struvite compared with the absence of curcumin.

Interestingly, the addition of curcumin does not affect the crystal morphology and habit.

In conclusion, curcumin has demonstrated its significant potential to be further investigated for its use in the case of struvite crystallization induced for the growth by Proteus mirabilis in relation to urinary stone formation.
