Correct Answer is E

Comment:

Answer E

Urea-splitting bacteria are Proteus, Klebsiella, Pseudomonas, Providencia, Serratia species, Staphylococcus aureus and Ureaplasma urealyticum. Proteus mirabilis accounts for more than half of all urease positive urinary infections. Urea-splitting bacteria change the urine pH (>7.2) and allow easier precipitation of phosphate with several compounds, mainly ammonium and magnesium. The result is struvite stones.
