So how many eukaryotics and how many prokaryotics are found in the human body?

"There are 20,000 species of prokaryotes in the human body at any given time."

- off-the-cuff response from a biology major

If you're asking about prokaryotic & eukaryotic cells OTHER than human cells, there are billions of organisms living on our skin, in our digestive tract, and just all over.
