What’s Up Microbes?

Health

AG-Nephele-side-by-side2There is no doubt that the little bugs that live inside our bodies and on our skin affect our health and well-being, even our state of mind, but what we want to know is, by studying them, can we prevent disease or even just a bad mood? And how can we monitor them on a daily basis? Will there be an app called “What’s up microbes?” that communicates with some new device that checks on those microbes and reports back what we should eat or if we should go see the doctor, or go for a run, or take it easy and relax to ensure we maintain a healthy microbial equilibrium?

A few months ago, I shipped my “gut microbiome” inside a narrow transparent tube via the US postal mail service to American Gut. My microbiome made the long trip from Miami to California stuck on a Q-tip. At the time, it seemed that the scientific research into this tiny new world of microbes had come a long way, but to my disappointment, I found out that there is still much to be learned. I found out that my microbiome had not survived the trip intact and had started to bloom, aka “grow new bacteria” during the trip.

In recent years, the microbiome has been featured prominently in the news as one of several paths to personalized medicine. Researchers from diverse fields such as psychology or nutrition or cancer, and many others, are trying to join the race to decipher it. There is great promise in its research, which is why the sector is receiving billions in funding, with major research initiatives in the US and worldwide. But as of today, the microbiome is still a mystery.

A 2014 article titled “20 Things you Didn’t Know About the Human Gut Microbiome” aptly describes the microbiome this way:

The microbiome is defined as all the bacteria, viruses, fungi, archaea, and eukaryotes that inhabit the human body. Collectively referred to as the “second human genome”, the gut microbiome in particular is now being considered a separate “organ” with distinct metabolic and immune activity. The two major areas of microbiota investigation include taxonomic diversity to identify “who” is there and functional metagenomics to figure out what they are doing. There are other human microbiome sites as well, including skin, oral, and vaginal, but the gut is the most popular and diverse neighborhood.
