"Robert Koch Heinrich Hermann Robert Koch (; ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist. As the founder of modern bacteriology, he identified the specific causative agents of tuberculosis, cholera, and anthrax and gave experimental support for the concept of infectious disease, which included experiments on humans and animals. Koch created and improved laboratory technologies and techniques in the field of microbiology, and made key discoveries in public health. His research led to the creation of Koch's postulates, a series of four generalized principles linking specific microorganisms to specific diseases that remain today the"

His studies in Germany demonstrated his accurate observation and original thought in the field of research. Returning from Berlin in 1890 he served as Obstetric Resident at St Bartholomew's Hospital While holding this position he was appointed by the Royal College of Surgeons, Royal College of Physicians, and the Executive Committee of the National Leprosy Fund as one of the Special Commissioners to investigate the prevalence and treatment of leprosy in India. Among his conclusions were that direct contagion"
"Robert Koch Medal and Award The Robert Koch Medal and Award are two prizes awarded annually for excellence in the biomedical sciences. These awards grew out of early attempts by Robert Koch to generate funding to support his research into the cause and cure for tuberculosis. Koch discovered the bacteria (""Mycobacterium tuberculosis"") responsible for the dreaded disease and rapidly acquired international support, including 500,000 gold marks from the Scottish-American philanthropist Andrew Carnegie. Since 1970, the Koch Foundation has awarded prizes for major advances in the biomedical sciences, particularly in the fields of microbiology and immunology. The prestige of this award"
"later that same year, he married actress Hedwig Freiberg (1872–1945). On 9 April 1910, Koch suffered a heart attack and never made a complete recovery. On 27 May, three days after giving a lecture on his tuberculosis research at the Prussian Academy of Sciences, Koch died in Baden-Baden at the age of 66. Following his death, the Institute named its establishment after him in his honour. He was irreligious.

In 1883, Robert Koch identified ""V. cholerae"" with a microscope as the bacillus causing the disease. Robert Allan Phillips, working at the US Naval Medical Research Unit Two in Southeast Asia, evaluated the pathophysiology of the disease using modern laboratory chemistry techniques and developed a protocol for rehydration. His research led the Lasker Foundation to award him its prize in 1967. More recently, in 2002, Alam, ""et al."", studied stool samples from patients at the International Centre for Diarrhoeal Disease in Dhaka, Bangladesh."

He then went to Berlin under Professor Robert Koch, a pioneering microbiologist and founder of modern bacteriology who received the Nobel Prize in 1905 for his groundbreaking research on tuberculosis; and subsequently to Frankfurt under Professor Paul Erhlich who received"

At the Tenth International Medical Congress held 1890 in Berlin, Koch unexpectedly introduced a cure for tuberculosis, which he called tuberculin. He did not reveal its composition, which is understandable as it was not then customary to patent medicine; Phenazone being the only exception. The public trusted the famous physician and reacted enthusiastically. Koch was awarded the Grand Cross of the Order of the Red Eagle. The social hygienist Alfred Grotjahn described the arrival"

This indicates that intracellular exposure of ""M. tuberculosis"" to reactive oxygen and/or reactive nitrogen species results in the formation of DSBs that are repaired by HR or NHEJ. However deficiency of DSB repair does not appear to impair ""M. tuberculosis"" virulence in animal models. ""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"

His pioneering work in the late 19th century was one of the first demonstrations that diseases could be caused by microbes. In a groundbreaking series of experiments, he uncovered the lifecycle and means of transmission of anthrax. His experiments not only helped create an understanding of anthrax, but also helped elucidate the role of microbes in causing illness at a time when debates still took place over spontaneous generation versus cell theory. Koch went on to study the mechanisms of"
"John Snow, ""et al."", as to contaminated drinking water being the likely source of the disease, relatively quickly identified the East London Water Company as the source of the contaminated water. Quick action prevented further deaths. During the fifth cholera pandemic, Robert Koch isolated ""Vibrio cholerae"" and proposed postulates to explain how bacteria caused disease. His work helped to establish the germ theory of disease. Prior to this time, many physicians believed that microorganisms were spontaneously generated, and disease was caused by direct exposure to filth and decay. Koch helped establish that the disease was more specifically contagious and was"

Immunology made a great advance towards the end of the 19th century, through rapid developments, in the study of humoral immunity and cellular immunity. Particularly important was the work of Paul Ehrlich, who proposed the side-chain theory to explain the specificity of the antigen-antibody reaction; his contributions to the understanding of humoral immunity were recognized by the award of a Nobel Prize in 1908, which was jointly awarded"

In the 18th century, Pierre-Louis Moreau de Maupertuis made experiments with scorpion venom and observed that certain dogs and mice were immune to this venom. This and other observations of acquired immunity were later exploited by Louis Pasteur in his development of vaccination and his proposed germ theory of disease. Pasteur's theory was in direct opposition to contemporary theories of disease, such as the miasma theory. It was not until Robert Koch's 1891 proofs, for which he was awarded a Nobel"

According to Koch’s colleague, Paul Ehrlich, “At this memorable session, Koch appeared before the public with an announcement which marked a turning-point in the story of a virulent human infectious disease. In clear, simple words Koch explained the aetiology of tuberculosis with convincing force, presenting many of his microscope slides and other pieces of evidence.” At the time of Koch's announcement"

"Koch–Pasteur rivalry The French Louis Pasteur (1822–1895) and German Robert Koch (1843–1910) are the two greatest figures in medical microbiology and in establishing acceptance of the germ theory of disease (germ theory). In 1882, fueled by national rivalry and a language barrier, the tension between Pasteur and the younger Koch erupted into an acute conflict. Pasteur had already discovered molecular chirality, investigated fermentation, refuted spontaneous generation, inspired Lister's introduction of antisepsis to surgery, introduced pasteurization to France's wine industry, answered the silkworm diseases blighting France's silkworm industry, attenuated a ""Pasteurella"" species of bacteria to develop vaccine to chicken cholera (1879),"

John Snow, who disproved the miasma theory, and Robert Koch, were widely and erroneously credited with the discovery of the bacillum 30 years later. Pacini's work was repeatedly published and readily available to the international scientific community via the English translation published in The British and Foreign Medico-chirurgical Review, Volume 38, July 1866.

In 1846, the Nuisances Removal and Diseases Prevention Act was passed to identify whether the transmission of Cholera is by air or by water. The bill was used to encourage the owner to clean their dwelling and connect them to sewers. Some years later in 1855, John Snow made a testimony against the Amendment to this bill that regularized air pollution of some industries. He claimed that: At the same year, William Farr, who was then the major"

The difference between smallpox vaccination and anthrax or chicken cholera vaccination was that the latter two disease organisms had been artificially weakened, so a naturally weak form of the disease organism did not need to be found. This discovery revolutionized work in infectious diseases, and Pasteur gave these artificially weakened diseases the generic name of ""vaccines"", in honour of Jenner's discovery. In 1876, Robert Koch had shown that ""Bacillus anthracis"" caused anthrax. In his papers published between 1878 and 1880, Pasteur only mentioned Koch's work in a footnote.

Thus throughout the majority of the 19th century, there was only the most basic, common sense understanding of the causes, amelioration and treatment of epidemic disease. The late 19th century was the beginning of widespread use of vaccines. The cholera bacterium was isolated in 1854 by Italian anatomist Filippo Pacini, and a vaccine, the first to immunize humans against a bacterial disease, was developed by Spanish physician Jaume Ferran i Clua in 1885, and by Russian-Jewish bacteriologist Waldemar Haffkine in July 1892.

This incident, together with nine deaths from tetanus from contaminated smallpox vaccine in Camden, New Jersey, led directly and quickly to the passing of the Biologics Control Act in 1902. Robert Koch developed tuberculin in 1890. Inoculated into individuals who have had tuberculosis, it produces a hypersensitivity reaction, and is still used to detect those who have been infected. However, Koch used tuberculin as a vaccine. This caused serious reactions and deaths in individuals whose latent tuberculosis was reactivated by the tuberculin. This was a major setback for supporters of"

In 1883, responding to a cholera epidemic in Alexandria, Egypt, both Pasteur and Koch sent missions vying to identify its cause. Koch returned victorious, whereupon Pasteur switched research direction and began development of rabies vaccine. As to public health, Koch's bacteriologists feuded with Max von Pettenkofer—whose miasmatic theory claimed the bacteria was but one causal factor among at least several—but von Pettenkoffer stubbornly opposed water treatment, and the massive cholera epidemic in Hamburg, Germany, in 1892 devastated von Pettenkofer's position, and German public health was grounded on Koch's"

These postulates, which not only outlined a method for linking cause and effect of an infectious disease but also established the significance of laboratory culture of infectious agents, are listed here: Robert Koch is widely known for his work with anthrax, discovering the causative agent of the fatal disease to be ""Bacillus anthracis"". He discovered the formation of spores in anthrax bacteria, which could remain dormant under specific conditions. However, under optimal conditions, the spores were activated and caused disease. To determine this causative agent, he dry-fixed bacterial cultures onto glass slides, used dyes to stain the cultures,"

Koch accepted government's offer to direct the Institute for Infectious Diseases (1891), in Berlin, a prestigious position but not the kind of institute that Koch had sought. It was later renamed the Robert Koch Institute, which remains a government organization. The monomorphist doctrine of Koch's bacteriologists suggested public health interventions to eliminate bacteria, whereas Pasteur's acceptance of variation suggested attenuating bacterial virulence in the laboratory to develop vaccines.

Since 1882, 24 March has been known as World Tuberculosis Day.

"When the 1902 Nobel Prize for Physiology or Medicine was considered, the Nobel Committee initially intended the prize to be shared between Ross and Grassi, however Ross accused Grassi of deliberate fraud. The weight of favour ultimately fell on Ross, largely due to the influences of Robert Koch, the appointed neutral arbitrator in the committee; as reported, ""Koch threw the full weight of his considerable authority in insisting that Grassi did not deserve the honor"". Ross was the first to show that malarial parasite was transmitted by the bite of infected mosquitoes, in his case the avian ""Plasmodium relictum"". Ronald"
