Man is the weak being who, in spite of all his self-importance and pride of wealth and capital, is vanquished by the smallest microbe.
The Microbe is so very small You cannot make him out at all, But many sanguine people hope To see him through a microscope.
Our bodies are home to trillions of microbes, and these creatures define who we are.
It is sometimes as dangerous to be run into by a microbe as by a trolley car.
If there is life, then I believe we should do nothing to disturb that life. Mars then, belongs to the Martians, even if they are microbes.
Microbes are just nature's janitors who work to clean up a poorly kept culturing medium. Trying to keep microbes off of and out of your body is like trying to keep the wind out of the trees.
As it takes two to make a quarrel, so it takes two to make a disease, the microbe and its host.
There are hundreds of thousands of microbes surrounding us, but they cannot harm us unless we become weak, until the body is ready and predisposed to receive them.
What's natural is the microbe. All the rest-heath, integrity, purity (if you like)-is a product of the human will, of a vigilance that must never falter. The good man, the man who infects hardly anyone, is the man who has the fewest lapses of attention.
Messieurs, c'est les microbes qui auront le dernier mot." (Gentlemen, it is the microbes who will have the last word.)
Most life on Earth is microbes. we've only just scratched the surface of the microbial realm. Probably less than .1% of microbes have been classified let alone cultured or had their genes sequenced, so really that microbial realm is a mystery.
There are more microbes per person than the entire population of the world. Imagine that. Per person. This means that if the time scale is diminished in proportion to that of space it would be quite possible for the whole story of Greece and Rome to be played out between farts.
The nature of a protective immune response to HIV is still unclear. Because in a very, very unique manner, unlike virtually any other microbe with which we're familiar, the HIV virus has evolved in a way that the immune system finds it very difficult, if not impossible, to deal with the virus.
The vast majority of terrestrial species are in fact microbes, and scientists have only begun scratching the surface of the microbial realm. It is entirely possible that examples of life as we don't know it have so far been overlooked.
Surely all God's people, however serious or savage, great or small, like to play. Whales and elephants, dancing, humming gnats, and invisibly small mischievous microbes- all are warm with divine radium and must have lots of fun in them.
For each illness that doctors cure with medicine, they provoke ten in healthy people by inoculating them with the virus that is a thousand times more powerful than any microbe: the idea that one is ill.
In the same way that plants will not grow on soil that lacks some substance indispensable to their growth, so microbes, these microscopic plants which cause infectious disease, are unable to grow in an organism which does not give them all the substances they need.
I was studying the impacts of fishing on ocean life, while the places that I loved so much continued to decline: less and smaller fish, less corals, and more microbes. I found myself writing the obituary of nature with increasing precision. Unsatisfied and frustrated, I felt like a doctor telling the patient how she is going to die, with excruciating detail. If I were that patient, I would have fired myself and looked for a doctor who would look for a solution.
We don't even know what species are out there, for the most part, particularly when you get down to the microbes and very small invertebrates. They make up the mass of the organisms around us, including the soil we depend on, the soil of cornfields as well as hardwood forests. We haven't taken ecology to the point where we can even make a crude prediction of what's going to happen when we've reduced the living world down to a certain level.
For theories and schools, like microbes and corpuscles, devour one another and by their strife ensure the continuity of life.
To demonstrate experimentally that a microscopic organism actually is the cause of a disease and the agent of contagion, I know no other way, in the present state of Science, than to subject the microbe (the new and happy term introduced by M. Sédillot) to the method of cultivation out of the body.
If it is a terrifying thought that life is at the mercy of the multiplication of these minute bodies [microbes], it is a consoling hope that Science will not always remain powerless before such enemies.
It is not difficult to make microbes resistant to penicillin in the laboratory by exposing them to concentrations not sufficient to kill them, and the same thing has occasionally happened in the body. The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant.
Fortunately, our immune system can be improved and empowered to such a point that not only can the harmful microbes be halted and the chemicals detoxified, but also a "stress defense shield" may be built up, which can even drive off the effects of daily stress.
"...The large majority of those infectious microbes that cause us so much illness and pain are ANAEROBIC...a big word that means they live and proliferate best in environments where there is LITTLE OR NO OXYGEN."
The immune systems goal is to protect the body against invaders either from without, such as microbes, or from within, such as cancers and different types of neoplastic transformation.
Skin, bones, blood and organs transplant from person to person. Even what’s inside you already, the colonies of microbes and bugs that eat your food for you, without them you’d die. Nothing of you is all-the-way yours. All of you is inherited. Whatever you’re thinking, a million other folks are thinking. Whatever you do, they’re doing, and none of you is responsible. All of you is a cooperative effort.
To ferment your own food is to lodge a small but eloquent protest - on behalf of the senses and the microbes - against the homogenization of flavors and food experiences now rolling like a great, undifferentiated lawn across the globe.
A hollow edifice erected for the habitation of man, rat, mouse, beetle, cockroach, fly, mosquito, flea, bacillus, and microbe.
All it takes,” said Crake, “is the elimination of one generation. One generation of anything. Beetles, trees, microbes, scientists, speakers of French, whatever. Break the link in time between one generation and the next, and it’s game over forever.
If Darwin could see what we now see, what we now know about the ocean, about the atmosphere, about the nature of life, as we now understand it, about the importance of microbes - I think he would just beam with joy that many of the thoughts and the glimpses of the majesty of life on Earth that he had during his life, now magnified many times over.
Perhaps dirt is the necessary condition of beauty.... Perhaps hygiene and art can never be bedfellows. No Verdi, after all, without spitting into trumpets. No Duse without a crowd of malodorous bourgeois giving one another their coryzas. And think of the inexpugnable retreats for microbes prepared by Michelangelo in the curls of Moses' beard!
If the age of the Earth were a calendar year and today were a breath before midnight on New Year's Eve, we showed up a scant fifteen minutes ago, and all of recorded history has blinked by in the last sixty seconds. Luckily for us, our planet-mates--the fantastic meshwork of plants, animals, and microbes--have been patiently perfecting their wares since March, an incredible 3.8 billion years since the first bacteria. ...After 3.8 billion years of research and development, failures are fossils, and what surrounds us is the secret to survival.
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.
An asteroid could hit us at any moment. This is not - and also, the most successful kind of life on this planet is not us, it's microbes. They're the ones who greatly outnumber us, and may eventually destroy us.
Our physical senses and our embodied brains allow us to perceive only a small fraction of reality. We cannot see microbes or untraviolet light, for example. We can hear only a small range of sounds. When we try to describe the otherworld of energies and spirits, we are limited not only by our bodily constraints but by the expectations, assumptions, and language patterns ingrained in us by the culture we were raised in.
My immune system has always been overly welcoming of germs. It's far too polite, the biological equivalent of a southern hostess inviting y'all nice microbes to stay awhile and have some artichoke dip.
In 1494, King Charles VIII of France invaded Italy. Within months, his army collapsed and fled. It was routed not by the Italian army but by a microbe. A mysterious new disease spread through sex killed many of Charles’s soldiers and left survivors weak and disfigured. French soldiers spread the disease across much of Europe, and then it moved into Africa and Asia. Many called it the French disease. The French called it the Italian disease. Arabs called it the Christian disease. Today, it is called syphilis.
There may be a million microbes of misery floating about us. Never mind! They dare not approach us, they have no power to get a hold on us, until the mind is weakened.
There are hundreds of thousands of microbes surrounding us, but they cannot harm us unless we become weak, until the body is ready and predisposed to receive them. There may be a million microbes of misery floating about us. Never mind! They dare not approach us, they have no power to get a hold on us, until the mind is weakened. This is the great fact: strength is life. Weakness is death. Strength is felicity, life eternal, immortal. Weakness is constant strain and misery: weakness is death
If man merely sat back and thought about his impending termination, and his terrifying insignificance and aloneness in the cosmos, he would surely go mad, or succumb to a numbing sense of futility. Why, he might ask himself, should he bother to write a great symphony, or strive to make a living, or even to love another, when he is no more than a momentary microbe on a dust mote whirling through the unimaginable immensity of space?
The important thing is that we now have the tools to sequence all kinds of animals and plants and microbes - as well as humans. It is not important that we didn't actually finish the human sequence yet.
The plague of racism is insidious, entering into our minds as smoothly and quietly and invisibly as floating airborne microbes enter into our bodies to find lifelong purchase in our bloodstreams.
To feel the anguish of waiting for the next moment and of taking part in the complex current (of affairs) not knowing that we are headed toward ourselves, through millions of stone beings - of bird beings - of star beings - of microbe beings - of fountain beings toward ourselves.
These microscopic organisms form an entire world composed of species, families and varieties whose history, which has barely begun to be written, is already fertile in prospects and findings of the highest importance. The names of these organisms are very numerous and will have to be defined and in part discarded. The word microbe which has the advantage of being shorter and carrying a more general meaning, and of having been approved by my illustrious friend, M. Littré, the most competent linguist in France, is one we will adopt.
We are inescapably the result of a long heritage of learning, adaptation, mutation and evolution, the product of a history which predates our birth as a biological species and stretches back over many thousand millennia... Going further back, we share a common ancestry with our fellow primates; and going still further back, we share a common ancestry with all other living creatures and plants down to the simplest microbe. The further back we go, the greater the difference from external appearances and behavior patterns which we observe today.
When we seed millions of acres of land with these plants, what happens to foraging birds, to insects, to microbes, to the other animals, when they come in contact and digest plants that are producing materials ranging from plastics to vaccines to pharmaceutical products?
When it comes to acid rain or oil spills or depleted fisheries or tainted groundwater or fluorocarbon propellants or radiation leaks or sexually transmitted diseases, national frontiers are simple irrelevant. Toxins don't stop for customs inspections and microbes don't carry passports. North America became a water and free-trade zone long before NAFTA loosened up the market in goods.
If you are the body, you are in terrible trouble! One small microbe will destroy it one day, if not an accident. You have but a short time to live in this world.
