A Quote by Friedrich Loeffler
If diphtheria is a disease caused by a microorganism, it is essential that three postulates be fulfilled. The fulfilment of these postulates is necessary in order to demonstrate strictly the parasitic nature of a disease:
1) The organism must be shown to be constantly present in characteristic form and arrangement in the diseased tissue.
2) The organism which, from its behaviour appears to be responsible for the disease, must be isolated and grown in pure culture.
3) The pure culture must be shown to induce the disease experimentally.
An early statement of Koch's postulates.

To prove that tuberculosis is caused by the invasion of bacilli, and that it is a parasitic disease primarily caused by the growth and multiplication of bacilli, it is necessary to isolate the bacilli from the body, to grow them in pure culture until they are freed from every disease product of the animal organism, and, by introducing isolated bacilli into animals, to reproduce the same morbid condition that is known to follow from inoculation with spontaneously developed tuberculous material.
Once a disease has entered the body, all parts which are healthy must fight it: not one alone, but all. Because a disease might mean their common death. Nature knows this; and Nature attacks the disease with whatever help she can muster.
There are three types of disease: body disease, mind disease, and nervous system disease. When the mind is diseased, the whole body is diseased. The yoga scriptures say “Manayeva manu ? ? kara a bandha mok ayo (this verse may be transliterated incorrectly),” the mind is the cause of both bondage and liberation. If the mind is sick and sad, the whole body gets sick, and all is finished. So first you must give medicine to the mind. Mind medicine: that is yoga.
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.
Evil is a disease; and worry over disease is itself an additional form of disease, which only adds to the original complaint.
Every effective drug provokes in the human body a sort of disease of its own, and the stronger the drug, the more characteristic, and the more marked and more violent the disease. We should imitate nature, which sometimes cures a chronic affliction with another supervening disease, and prescribe for the illness we wish to cure, especially if chronic, a drug with power to provoke another, artificial disease, as similar as possible, and the former disease will be cured: fight like with like.
Simulated disorder postulates perfect discipline; simulated fear postulates courage; simulated weakness postulates strength.
We must treat the disease of racism. This means we must understand the disease.
People still think of AIDS as a shame-based disease, it's a sexually transmitted disease, and you're either gay or you're a prostitute or an intravenous drug user. And so a lot of people are still very bigoted about this disease. It's such a treatable disease. It's so - the end is in sight for this disease, medically.
Many physical illnesses are associated with depression and anxiety, including heart disease, high blood pressure, diabetes, Parkinson's disease, stroke, kidney disease, lung disease, dementia and cancer.
The Carter Center has the only existing international taskforce on disease eradication. Which means a total elimination of a disease on the face of the Earth. In the history of the world, there's only been one disease eradicated: smallpox. The second disease, I think, is gonna be guinea worm.
Against the disease of writing one must take special precautions, since it is a dangerous and contagious disease.
... After it has been determined that the pathogenic organism is present in the animal body, and after it has been shown that the organism can reproduce in the body and be transmitted from one individual to another, the most important experiment remains to be done....to determine the conditions necessary for growth and reproduction of the microorganism.
(there is) no other means of escaping from one's consciousness than to deny it, to look upon it as an organic disease of the terrestrial intelligence - a disease which we must endeavor to cure by an action which must appear to us an action of violent and willful madness, but which, on the other side of our appearances, is probably an action of health. ("Of Immortality")
According to the Western model, pregnancy is a disease, menopause is a disease, and even getting pregnant is a disease. Dangerous drugs and devices are given to women, but not to men- just for birth control. I've reached the conclusion that to many doctors BEING A WOMAN IS A DISEASE
Alzheimer's is a devastating disease. It was painful for me and my family to watch my grandfather deteriorate. We must find a cure for this horrible disease.
