Scientists discover distinctive bacteria to identify dog persons
When you have a dog in your life your skin is crawling with betaproteo- and andactinobacteria and there’s no way out, but not to worry, because, as often is the case the name is more intimidating than the actual bacterium itself, as it pertains to a harmless mixture of bacteria that do not posses a direct threat to our health, that is of course your immune system has not developed an allergic reaction to it.
The bacteria are mainly transferred to us (dog persons) when there’s direct contact between our skin and the dog’s tongue and/or paw.
The interesting thing is that dog lovers the world over share the same kind of skin bacteria as two people living together in an intimate relationship.
The following is an excerpt of the original article but I urge you to read this simply amazing article in its entirety by clicking the link at the bottom of the page.
Well, it looks like there really is such as thing as a dog person.
Humans who share their homes with canines also share the similar bacterial house guests on their skin, ecologists reported Tuesday in the journal eLIFE.
In fact, two dog owners who don’t even know each other have about as many of the skin bacteria in common as a married couple living together.
The signature doggie blend is a mixture of harmless bacteria from their tongues and paws, the report finds. Microbial sharing from pooch to person occurs primarily through two routes: tongue to skin and paw to skin.
There wasn’t an analogous germ signature for cat owners, the scientists say. Cats are more selfish?
Collectively, this microscopic zoo is called themicrobiome. And it plays a critical role in human health. It helps to set your metabolism, fine-tune your immune system and even freshen (or sour) your breath.
To see how canine cohabitation could alter the species in this zoo, Rob Knight and his team at the University of Colorado, Boulder, characterized the bacteria shacking up with 60 families – 25 of them had at least one dog, including big breeds, like German shepherds, Labrador retrievers and huskies.
Humans living together shared similar bacteria at all three body sites: skin, mouth and gut. But for dogs, it was all about the skin.
Two types of pooch bacteria were flourishing on dog owners’ skins:Betaproteobacteria, a group of critters that hang out on dogs’ tongues, andactinobacteria, which live in soil and like to nestle in the nooks of dogs’ paws.
These findings are “consistent with a common occurrence of oral–skin transfer between dogs and their owners,” the authors write.
Looks like, all those slurpy dog kisses really do have a long-lasting effect on your skin’s ecology.

This study can’t say. But we do know that innocuous bacteria on the skin help the immune systems learn the difference between good and bad germs. And allergies can crop up when this ability short circuits.
Recent studies have even linked up contact with pets when we’re young with a decreased risk of allergies and autoimmune disorders later in life.
Now if you’ll excuse me, I need to go snuggle up with my very stinky German shepherd.
