A Quote by Richard Dawkins
For the first half of geological time our ancestors were bacteria. Most creatures still are bacteria, and each one of our trillions of cells is a colony of bacteria.

Most bacteria aren't bad. We breathe and eat and ingest gobs of bacteria every single moment of our lives. Our food is covered in bacteria. And you're breathing in bacteria all the time, and you mostly don't get sick.
All these bacteria that coat our skin and live in our intestines, they fend off bad bacteria. They protect us. And you can't even digest your food without the bacteria that are in your gut. They have enzymes and proteins that allow you to metabolize foods you eat.
Bacteria are single-celled organisms. Bacteria are the model organisms for everything that we know in higher organisms. There are 10 times more bacterial cells in you or on you than human cells.
To declare war on ninety-nine percent of bacteria when less than percent of them threaten our health makes no sense. Many of the bacteria we're killing are our protectors.
I love weird science. I learned in an article in 'National Geographic' that there are trillions of bacteria in our guts that help us digest food. These are non-human creatures.
Since we're living with antibiotic drugs and chlorinated water and antibacterial soap and all these factors in our contemporary lives that I'd group together as a 'war on bacteria,' if we fail to replenish [good bacteria], we won't effectively get nutrients out of the food we're eating.
Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.
[Bacteria] have an incredibly complicated chemical lexicon that ... allows bacteria to be multicellular. In the spirit of TED they're doing things together because it makes a difference.
Teeth represent only 10 percent of the surface of your mouth and bacteria live throughout the whole mouth. When you stop brushing, bacteria left behind resettle on your teeth and gums. Oil pulling reaches virtually 100 percent of the mouth, thereby affecting all bacteria, viruses, fungi, and protozoa in the mouth.
It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria are the Gram-negative bacilli, and the most susceptible are the pyogenic cocci ... In addition to its possible use in the treatment of bacterial infections penicillin is certainly useful... for its power of inhibiting unwanted microbes in bacterial cultures so that penicillin insensitive bacteria can readily be isolated.
Think about multicellularity on this Earth. Every living thing originally came from bacteria. So, who do you think made up the rules for how to perform collective behaviors? It had to be the bacteria.
We have 200 trillion cells, and the outcome of each of them is almost 100 percent genetically determined. And that's what our experiment with the first synthetic genome proves, at least in the case of really simple bacteria. It's the interactions of all those separate genetic units that give us the physiology that we see.
Bacteria evolve, and so they become resistant to existing drugs. Sometimes they revert, depending on how damaging the mutation is to the life cycle of the bacteria. Mutations that give rise to resistance against particular compounds do increase, and that is why you constantly have to have new ones.
It's incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.
Nineteen hundred and three will bring great advances in surgery, in the study of bacteria, in the knowledge of the cause and prevention of disease. Medicine is played out. Every new discovery of bacteria shows us all the more convincingly that we have been wrong and that the million tons of stuff we have taken was all useless.
However, on many occasions, I examined normal blood and normal tissues and there was no possibility of overlooking bacteria or confusing them with granular masses of equal size. I never found organisms. Thus, I conclude that bacteria do not occur in healthy human or animal tissues.
