Human Body Host for Bugs?

The human body relies on bugs for health and life. Without the microbes the human body plays host to, there would be no human life. Scientists tell us we are 90% bugs and 10% human. The number of microbes our lives depend are staggering. Maybe it would be more appropriate to label ourselves as a "human-microbe hybrid".


The human body is host to 100 trillion microbes. Without these “bugs” we could not live. They are vital to human life and without them there would  be no human life. These vast number of bugs that live in the body have vital work to do. The DNA of these bugs have been found to contain 60,000 genes, twice the number found in our own DNA. They carry the code for enzymes that humans don’t have and do things humans can’t do. When all is told, each of us is really a human-microbe hybrid.

 The human body contains only 10 trillion cells while  we are host to 100,000  trillion microbes. Scientist jokingly say that a human is 90% microbes and 10% human. The total weight of all those microbes in one body is about the weight of our own liver. These bugs live in our mouth, eyes, reproductive organs and in our gut. Millions live in our gut alone. We could not digest food without them. In the colon these bugs synthesise our vitamins and breaks down fiber. In fact without these vital bugs we could not live  or even be born.

 Scientists are currently at work labeling all these bugs that are so vital for life and health. Already over 1,000 species in the gut have been labeled. Among many other studies new connections are coming to light about how bacteria can effect how fats are processed, and the likelihood of developing diabetes.  How microbes effect other diseases are also being studied. Scientists are seeing possibilities in improving health by meddling with our microbes.

 First signatures of all the chemicals that mirobes interactions create in the body will be collected. Then computers will go through vast lists of information and look for metabolic profiles that coralate with health and disease. Scientists will then search for ways to alter them. It might be with diet, drugs, or probiotics that contain helpful bacteria. 

Isn’t it shocking to think how we fight every little bug we see with insect repellent and yet we are loaded with bugs who do the work that keeps us alive. Maybe we should  put the bug spray away and appreciate bugs. After all we are 90% bugs.

    I like this concept and I have written an article titled “think about relationships” which is about the parasites that thrive inside ourselves. I like the picture, Ruby. Well, thinking about beauty, one must think underneath the skin,lol.

    i was from Science class last time but all knowledge returned to the school, now I feel myself back to the Biology lesson. Very interesting post about the human body, Ruby, clicked you “liked it” as usual.

    Yes Ruby very good. I have often wondered about the flu vaccine and our own ability to fight off flu for example. Vaccines are filled with bacterias that are cultured I believe and most ppl are made sick soon after the shot. Now with swine flu and others this is repeated as well. Well done Ruby our own inner bugs are good for us.

    That’s amazing information. I had no idea we were so filled with bugs and bacteria. It really makes you think. A great post.

    We spend all our time to trying to stay bug free and never stop to think that there are actually ones that help us. Good article though a little creepy

    Microbes were here before us and will probably be here after us, just like cockroaches.

    Another great entry. It is true that microorganisms play a very important role in our lives and those of other animals and plants.

    Thank you Ruby for a very educational Biology lesson. I was surprised to know that a human is 90% microbes and 10% human

    I never spray bug poison.. its odd to think but the bugs in our house want to live just as much as we do… and to think we NEED these bugs in our body so we should want THEM to live too. cool info.

    Yes, there are good bugs and bad bugs. Too many bad bugs is bad, but too few good bugs is just as bad. Wonderful reading.

    Interesting article, Ruby. Intresting that every living thing has a host of other living things some are negative and others positive…. Just think – our Creator is truly a master scientist.

    As much as we think we control our own bodies, here you go showing that we have our own little circle of interdependent organisms.
