Bacteria Again

…and speaking of bacteria, according to Science Magazine (23rd May, 2008)[link]:

Thanks to ever-evolving gene-sequencing technology, scientists can now use microbial RNA to identify organisms. With these techniques, researchers have found an unexpectedly wide variety of bacteria on human skin…

The researchers found about 1000 species total, which were fairly consistent from person to person; it turns out we all have similar tenants in our noses and on our backs. The number suggests that our skin is as variegated as our guts, which house anywhere from 500 to 1000 bacterial species.

That’s number of species, mind you, not number of bugs. Don’t shake my hand next time I meet you.
