* HIV fulfills Koch's postulates, which are one set of criteria for demonstrating a causal relationship between a microbe and a disease.

( Subsequently, additional data further demonstrated the fulfillment of Koch's postulates.

He became famous for isolating Bacillus anthracis ( 1877 ), the Tuberculosis bacillus ( 1882 ) and Vibrio cholerae ( 1883 ) and for his development of Koch's postulates.

Probably as important as his work on tuberculosis, for which he was awarded a Nobel Prize in 1905, are Koch's postulates, which say that to establish that an organism is the cause of a disease, it must be:

Koch was also famous for the discovery of the tubercle bacillus ( 1882 ) and the cholera bacillus ( 1883 ) and for his development of Koch's postulates.

One way of proving that a given disease is " infectious ", is to satisfy Koch's postulates ( first proposed by Robert Koch ), which demands that the infectious agent be identified only in patients and not in healthy controls, and that patients who contract the agent also develop the disease.

Based on these experiments, he devised criteria for establishing a causal link between a microbe and a disease and these are now known as Koch's postulates.

In late 1918, French scientists showed that a " filter-passing virus " could transmit the disease to people and animals, fulfilling Koch's postulates.

Koch's postulates () are four criteria designed to establish a causal relationship between a causative microbe and a disease.

Koch's postulates are:

In summary, a body of evidence that satisfies Koch's postulates is sufficient but not necessary to establish causation.

Koch's postulates were developed in the 19th century as general guidelines to identify pathogens that could be isolated with the techniques of the day.

Even in Koch's time, it was recognized that some infectious agents were clearly responsible for disease even though they did not fulfill all of the postulates.

Attempts to rigidly apply Koch's postulates to the diagnosis of viral diseases in the late 19th century, at a time when viruses could not be seen or isolated in culture, may have impeded the early development of the field of virology.

Currently, a number of infectious agents are accepted as the cause of disease despite their not fulfilling all of Koch's postulates.

Therefore, while Koch's postulates retain historical importance and continue to inform the approach to microbiologic diagnosis, fulfillment of all four postulates is not required to demonstrate causality.

Koch's postulates have also influenced scientists who examine microbial pathogenesis from a molecular point of view.

In the 1980s, a molecular version of Koch's postulates was developed to guide the identification of microbial genes encoding virulence factors.

* Molecular Koch's postulates

#* Koch's postulates were the first criteria developed for epidemiological relationships.

* Koch's postulates, the criteria required to establish the etiology of an infectious disease

* Robert Koch and Friedrich Loeffler formulate Koch's postulates on the causal relationship between microbes and diseases.

* December 11-Robert Koch ( died 1910 ), German physician, famous for the discovery of the tubercle bacillus ( 1882 ) and the cholera bacillus ( 1883 ) and for his development of Koch's postulates ; awarded the Nobel Prize in Physiology or Medicine in 1905

A hagiographic account of Koch's career can be found in the 1939 Nazi propaganda film Robert Koch, der Bekämpfer des Todes ( The fighter against death ), directed by Hans Steinhoff and starring Emil Jannings as Koch.

In 1969, Union Oil began trying to market their interest in Great Northern by telling potential buyers that Koch's controlling interest could be thwarted by currying favor with another owner, J. Howard Marshall II.

That outing would turn out to be the turning point in Koch's career ; he later was quoted as saying that he felt like ' shooting himself ' after that loss.

The well-known Koch's Postulates, are 19th-century constructs developed by Robert Koch to establish the likelihood for Bacillus anthracis causing anthrax disease and are not applicable to viral diseases ( Firstly, viruses cannot truly be isolated in pure culture-even stringent isolation techniques cannot exclude undetected contaminating viruses with similar density characteristics and viruses must be grown on cells.

In 1982, on the one-hundredth anniversary of Robert Koch's presentation, the International Union Against Tuberculosis and Lung Disease ( IUATLD ) proposed that March 24 be proclaimed an official World TB Day.

Pseudomembranous colitis was first described as a complication of C. difficile infection in 1978, when a toxin was isolated from patients suffering from pseudomembranous colitis and Koch's postulates were met.

Koch's pupils found the organisms responsible for diphtheria, typhoid, pneumonia, gonorrhoea, cerebrospinal meningitis, leprosy, bubonic plague, tetanus, and syphilis, among others, by using his methods.

As for Koch's personal life, he had no interest in politics and religion did not play a role in his life.

It was not until Robert Koch's 1891 proofs, for which he was awarded a Nobel Prize in 1905, that microorganisms were confirmed as the cause of infectious disease.

Y Gododdin is known only from a 13th-century manuscript, so it is impossible to determine whether this passage is original or a later interpolation, but John Koch's view that the passage dates from a 7th-century or earlier version is regarded as unproven ; 9th-or 10th-century dates are often proposed for it.

Walter Karl Koch ( 3 May 1880 in Dortmund, Germany-1962 ) was a German surgeon best known for the discovery of Koch's triangle, a triangular shaped area in the right atrium of the heart, and of Tawara's node, the atrioventricular node which is the beginning of the auricular-ventricular bundle.

In 2005, Koch's Flint Hills Resources refinery was recognized by the Environmental Protection Agency's Clean Air Awards program for reducing air emissions by 50 percent while expanding operations.

Koch's Matador Ranch in Texas earned the Lone Star Land Steward award for outstanding natural resource management in 2010.

He fought anti-obscenity provisions that Congress briefly imposed on the National Endowment for the Arts during the Reagan Presidency, and he chose to produce The Normal Heart, which passionately decried institutionalized " homophobia " as well as Mayor Koch's response to the AIDS crisis.

M. tuberculosis, then known as the " tubercle bacillus ", was first described on 24 March 1882 by Robert Koch, who subsequently received the Nobel Prize in physiology or medicine for this discovery in 1905 ; the bacterium is also known as " Koch's bacillus ".

Koch's hull was protected by a belt of ice-floe resistant flush skin-planking ( made of oak or larch ) along the variable water-line, and had a false keel for on-ice portage.

As the series progresses, Koch's role alters to that of being a useful spy for Moser in certain situations where his team is too well-known.

Their journey was documented for Sunrise and finished with a televised Anzac Day service, during which Koch's group controversially wore t-shirts advertising Seven News, which were prominently visible in the Sunrise broadcast.

The opposition in the Hessian state government claimed that these funds were used in particular for the financing of Roland Koch's electoral campaign ( CDU Prime Minister of Hesse ), and tried to have the election ( which he won ) voided ; this attempt failed, however.
