Critters Among Us: 3 Bugs That Live On You

You can’t feel it right now, but there are bugs all over you.

Before you freak out and jump in the shower, rest assured that if it weren’t for some of these microscopic critters, you probably wouldn’t be here. Many of these bugs keep us healthy and on any given day, you’re sharing your body with about 90 trillion or so.

In other words, resistance is futile!

So, who’s setting up shop on your body? Here are 3 animals that call you home.

DEMODEX

Do you recognize this one? Eight-legged demodex is a worm-like mite that likes to hang out near hair follicles. Specifically, this guy is particularly partial to your eyelashes. Adults are only 0.03 mm long, so you won’t actually see them crawling around up there. The cool thing about these guys? Their bodies are so efficient, they only have a mouth. That is to say, ahem, that there is no exit. They use everything they eat without any waste!

LACTOBACILLUS ACIDOPHILUS

Don’t let the big name on this fella freak you out – lactobacillus is one of the good guys. In fact, I bet most of you have even walked into a grocery store and purposely bought food with Mr. Lactobac in it. You know all those commercials for yogurt that are pimping out the good bacteria? They’re talking about this one. Lactobacillus lives throughout your body, especially in your mouth and stomach. With this guy on the job, most people have improved immune function and a healthier GI tract. Eat up!

YOUR DNA

Yup, you read that right. Research has shown that 8% of our DNA comes from a virus and not one of our ancestors. This happens through a process called endogenization. These viruses (called bornaviruses) can cause disease in horses and sheep. Thankfully, we are not horses nor sheep. For the most part, we seem to be doing okay with this virus within us. It’s possible that this viruses causes mutation that leads to schizophrenia, but the labcoats haven’t ironed out all the details on that one.
