Researchers have found that bacteria in the blood of healthy people may help trigger strokes and heart attacks, and perhaps also contribute to conditions like Alzheimer's disease, diabetes and arthritis.
Blood has always been considered free from microbes, because bacteria don't grow when it is put in a culture dish. But recent DNA sequencing methods reveal that each millilitre of blood in fact contains around 1000 bacterial cells.
I've similarly been suspicious of claims that urine is sterile. After learning about microbes — I've long assumed very few places in our bodies are free from microbes and it was a continuous war with different battles going on at different places. Something like WW1 trench warfare — having to wait for the bacteria or virus (e.g. herpes zoster) to "stick its head up". You'd have to be extremely lucky (or dead) to have a complete ceasefire.

all those blood treatments like ultraviolet irradiation exit the crackpot science stage...
