How much of me is human vs. microbe

From All Things Considered on 13-June,

“‘The human we see in the mirror is made up of more microbes than human,’ said Lita Proctor of the National Institutes of Health, who’s leading the Human Microbiome Project.”

Read that quote again. I am not exactly sure what she is trying to say. I think what she is meaning to say is that there are more microbe entities than human cells.
Or is she implying that pound for pound, there is more microbe mass than human mass in and on me?

Other sites validate the former. I have a hard time believing the latter.

I read just this morning that the amount of microbes, if all gathered somehow, might actually add up to “a few pounds.”

Ok. So I was right. The journalist probably just did what journalist do - completely bungle the meaning of any quote or concept even slightly scientific.

Not really. From the article, here is the paragraph that precedes the quote you posted:

In that context, “more microbes” means the number of cells, not the weight of the microbiome.

So antibiotics wouldn’t make such great weight loss pills?

If you killed all the microbes in your body, weight loss would be the least of your problems.

There’s an error if they are including viruses in the total of cells, since viruses are non-cellular.

As has been said, our bodies contain many more bacterial cells than human cells. However, the bacterial cells make up only a small percentage of our weight.

So, yes, they are screwing up anything even remotely scientific.

Not if they are comparing the number of microbes to the number of human cells. Many microbiologists include viruses as microbes.

Yeah, and how much of that are you really seeing in the mirror anyway? My guess would be roughly none.

So you are taking that statement literally?

Well, yeah - kind of. Otherwise, I’m not sure what the reference to the mirror was for.

I’m guessing you find life very irritating.

Sometimes. Not today, though.

eta: Maybe it’s just because we don’t know each other well - but my sense of humor is pretty dry sometimes.

Darth, I might not know you very well, but I’m on quite good terms with your microbes.

In the quote in your second post, they are in fact comparing the number of human cells to the number of microbe cells, and even if you count viruses as “microbes” they don’t have cells.

ROFL! There’s nothing more amusing for the sarcasm-deficient than watching two dry-humour types reduced to fisticuffs because neither can recognize the other’s attempt to joke. :stuck_out_tongue:

Yeah, they grow on you.
