Corynebacterium urealyricum


Hello there.
You can call me C. urealyricum.
I'm a Gram Positive rod shaped bacteria.
My shape is irregular and I can't make endospores.
Unfair!

I can cause urinary tract infections by breaking a chemical called urea into little bits.
Ammonia crystals get left over and get stuck in your kidneys.
I am also very good at giving you kidneys stones.
