Question

The human body contains roughly 100 trillion cells. approximately what percentage of those cells are independent microorganisms?

Answer 1

I think the answer is 90%. According to the recent National institute of Health, Microbes in the human body estimates that 90% of the cells in human body are bacterial, fungal, or otherwise non-human. Despite the arguments that bacteria enjoys a commensal relationship with the humans hosts, only a fraction of the human microbia has been characterized. 

Answer 2

Answer:

According to some research, the bacterial count in our body is 10 times more than the count of cells the human body is made up of.  

This means that out of every ten cells nine cells are microbial cells so at least 90% of cells in the human body are the cells of independent microorganisms.

Trillions of microbial cells alone present in our intestine which outnumbers the cells human body is made up of. Microbes live in symbiotic relationship with our body and play an important role in our survival. Microbes normally present in or on our body is called human microbiome.
