Microoganisms
As far back as we know, animals have been home to microbes. Scientists have known for some time that these tiny tenants have the ability to make humans powerfully sick, while others are vital to maintaining the body's normal flora and fauna.
Collectively, the microbes inside everyone make up the "microbiome" — what microbiologist Martin Blares of the NYU School of Medicinedefines as "all the organisms that call us home, that live in us and that interact with each other and with ourselves." These teensy creatures, from bacteria and fungi to protozoans (mostly single-celled animal-like organisms), have a surprisingly rich story to tell. Here are five fascinating facts about the critters that call your body home. |
