Heinrich Hermann Robert Koch (/ k ɒ x / KOKH; [1] [2] German: [ˈʁoːbɛʁt ˈkɔx] ⓘ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist.As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology.
Koch contributed greatly to science related to the specificity of bacteria . He discovered and confirmed that a specific bacteria causes a specific illness. [62] In the 1870s, anthrax was a major cause of concern to both farmers and people living in the area of an outbreak.
The symptoms in anthrax depend on the type of infection and can take anywhere from 1 day to more than 2 months to appear. All types of anthrax have the potential, if untreated, to spread throughout the body and cause severe illness and even death. [24] Four forms of human anthrax disease are recognized based on their portal of entry.
Anthrax can enter the human body through the intestines (gastrointestinal), lungs (pulmonary), or skin (cutaneous), and causes distinct clinical symptoms based on its site of entry. [13] Anthrax does not usually spread from an infected human to an uninfected human. [13]
Koch's postulates (/ k ɒ x / KOKH) [2] are four criteria designed to establish a causal relationship between a microbe and a disease. The postulates were formulated by Robert Koch and Friedrich Loeffler in 1884, based on earlier concepts described by Jakob Henle , and the statements were refined and published by Koch in 1890. [ 3 ]
Symptoms in humans usually begin between one day to one week after exposure, but it may take as many as 60 days for them to present in humans. Symptoms depend on how anthrax enters the body.
It was killing people, one at a time, day by day. Between October 5, and November 22, 2001, five people who were exposed died from anthrax poisoning. Seeking experts. Anthrax. Saddam Hussein? Bin ...
In 1876, German biologist Robert Koch discovered that a bacterium (Bacillus anthracis) was the causative pathogen of anthrax, which became the first demonstration that a specific bacterium caused a specific disease and the first direct evidence of germ theory of diseases.
