There are some illnesses that may predispose a cat to struvite
Results showed that crop emergence in the control treatment, except for struvite
, was significantly higher than the emergence in the DAP and organic fertilizer treated plots at the Bahati and Lanet sites (Table 1).
 Alkaline urine caused by urea-splitting organisms (Proteus, Klebsiella, Serratia and Enterobacter) is responsible for struvite
stones (ammonium magnesium phosphate stones).
This characteristic means chemical reactions, such as precipitation to form struvite
or calcium phosphate, require extensive chemical additions or take place very slowly (Ibarra, 2011).
In present study, struvites
were found to be the most common crystals both in canines and bovines.
stones form in response to an infection, such as a urinary tract infection, while uric acid stones occur in people whose diet is high in purine and in those who have gout.
stones are one of the most common causes of staghorn calculi which are known to potentially form rapidly, in the order of 4 to 6 weeks (8).
renal stones form in the presence of urea-splitting bacterial organisms.

crystals in the presence of herbal extract Commiphora wightii," Journal of Materials Science, vol.
In this reaction, a phosphate gel was formed as a precursor of the ceramics since the metal oxide dissolved to release cations reacted with the hydrolytic phosphate ions, and the main final phase of hydration product is struvite
, but many other phases also existed during or after hydration reaction, such as dittmarite (N[H.sub.4]MgP[O.sub.4]*[H.sub.2]O), schertelite ([(N[H.sub.4]).sub.2]Mg[(HP[O.sub.4]).sub.2]*4[H.sub.2]O), newberyite (MgHP[O.sub.4]*3[H.sub.2]O), and magnesium phosphate hydrate [Mg.sub.3][(P[O.sub.4]).sub.2]*4[H.sub.2]O [12, 13].

The crystallised mineral forms of magnesium and calcium are known as struvite
, which is magnesium ammonium phosphate, and apatite, a poorly crystallised form of hydroxylated calcium phosphate .
