There are entire “;cities”; of bacteria inside your mouth and researchers want to map them all。 This is what they look like:

Gary Borisy wants to map out colonies of microbes much like neighborhoods and cities。 But there’;s a problem。

“You don’t have the addresses。 You don’t have a GPS。 You don’t know where they are,” said Borisy, a senior research investigator at the department of microbiology at the Forsyth Institute in Cambridge, Mass。 “We’re trying to provide a piece of the puzzle to figure out how the city of microbes works by seeing where they live and who lives next to what。”

With the development of scientific equipment, researchers are having a better and better understanding of the genetic make-up of the bacteria inside our bodies。 But we still don’;t know too much about how these communities are organized, and how they interact with each other and our bodies。

The first step in this is mapping the microbes。 Seeing where they are in relation to each other will give us the first ***ications regarding these relationships。

“I look at microbial communities as neighborhoods, and I want to know who’s next to who and why it’s significant,” said Borisy。 Bacteria in nature live in complex, multi-species communities in which bacterial cells that are in close proximity can exchange metabolic products and signals。 “The structural relationships of these communities mean something, and until now we have never been able to visualize them。”

For now, Borisy and his team are focusing on the mouth –; it seems like a good place to start, and surprisingly, one for which we’;re mostly clueless。 They mined the Human Oral Microbiome Database and the Human Microbiome Project for clues and came up with a list of 13 species of bacteria commonly found on teeth。
