Gah - that is a bad conclusion to draw from that study. There are some 39 trillion bacterial cells in a human body, and ~30 trillion 'human' cells in our body. EXCEPT that 25 of the 30 trillion human cells in our body don't even have any human DNA in them (red blood cells lack a nucleus, cannot divide, and do not contain human genetic information).

It's hard to count human cells, and non-human cells. Counting mass, nuclei, activity, etc. are all different.

The original hypothesis still stands - a truly significant portion of you is not human.
