Kat,
Good work! These crystals named above are in the myiasis research being drafted, in the following context:
Just one principle of myiasis is that acidic conditions starve larvae. They survive and thrive in alkaline conditions with a pH between 8-9, and have secretions that chemically induce alkalinity. They do this by secreting ammonia, causing wounds to become more alkaline, which is believed to inhibit bacterial growth. Production of ammonia (NH3) makes the urine more alkaline. If left untreated, the increased alkalinity can lead to the formation of crystals of struvite, calcium carbonate, and/or apatite. Once the stones develop, over time they may grow large enough to cause obstruction and renal failure.
Another photo of apatite:
I'm not sure whether they are the cause of some glitter type samples - werent they tannin/organophosphate on the raman graphs? It would sure explain the renal disfunction though hey!
Its feels close....
