Cystitis, or bladder infection, is the most common urinary tract infection. It occurs in the lower urinary tract (the bladder and urethra) and nearly always in women. In most cases, the infection is brief and acute and only the surface of the bladder is infected. Deeper layers of the bladder may be harmed if the infection becomes persistent, or chronic, or if the urinary tract is structurally abnormal. Uncomplicated urinary tract infections (UTI’s) are due to a bacterial infection, most often E. coli. Microscopic examination of the urine sample shows e.g. the presence of white blood cells and bacteria.

Diatoms - Jewels of the Sea

Diatoms are unicellular algae that are found wherever there is water and sufficient light to stimulate photosynthesis. The cells may be free floating (planktonic) or attached to a substratum (sessile). The diatom cell possesses the property of being able to surround itself with a more or less rigid box-like (like a covered petri dish) skeleton of hydrated silica called a frustule. The classification of diatoms is largely based on frustule form and sculpture. Diatoms range greatly in size from 5 – 2000 μm in length, although most species encountered are in the size range 20 – 200μm.

Around 1800 there was more life in the brewery and the plant was pulled into bloom in the Botanical Gardens of Madrid. Later, the plant was seeded and grown in the Botanical Gardens of Berlin.
