Comment from a microbiologist.......

"No, No, and NO! (Molecular microbiologist here to help...)
You'll notice the oh-so-slight caveat, "similar to..." In other words, they did NOT find fecal bacteria; they found bacteria that is related to fetal bacteria. Close relatives of fecal bacteria live in the soil, on our skin, in our mouths, in our eyes, in lakes and streams, etc., etc. In other words, nothing even remotely surprising there.
And of course they didn't say HOW closely related. In the same way that we are related to Neanderthals, but also related to slime molds, relatedness is a degree-measure. It's not related-or-not. You are related to your brother. You are also related to the last emperor of the Ming dynasty. Those relationships are not exactly of the same degree.
Lastly, the charge that we should all scrub our beards more is actually very bad advice and goes against what medical microbiology has been trying to teach us over the past decade. Most of us bathe too much and too harshly. The bacteria on our skin and in our hair is not only harmless, it's GOOD. Stripping it away constantly damages skin and creates openings for harmful bacteria to enter.
