Robert Koch also set down a series of 4 postulates that are essential for proving the pathogenicity of an organism. Microbiology (from Greek μῑκρος, mīkros, "small"; βίος, bios, "life"; and -λογία, -logia) is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). ...

Koch's Postulates are a series of steps to show that a specific microorganism causes a particular disease c. Koch and colleagues significantly advanced microbiology lab techniques F. In 1988, Stanley Falkow (1934–) proposed a revised form of Koch’s postulates known as molecular Koch’s postulates.These are listed in the left column of Table 1. A specific organism can always be found in association with a given disease 2. These provided a clear basis for scientific testing of the theory, The German scientist, Robert Koch, (1843-1910) a bacteriologist, physiologist and one of Pasteur's contemporaries, laid out the proper testing procedure, which is still considered an excellent example of scientific methods. Robert Koch, a German physician, defined the procedure (Koch’s postulates) for proving that a specific organism causes a specific disease. A microbiologist has identified a new gram-negative pathogen that causes liver disease in rats. Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology and parasitology.

Inoculation of a healthy host and obtaining the symptoms originally observed in the field may be difficult. He proposed Koch postulate which were published in 1884 and are the corner stone of the germ theory of diseases and are still in use today to prove the etiology (specific cause) of an infectious disease. He investigated the anthrax disease cycle in 1876, and studied the bacteria that causes tuberculosis in 1882, and cholera in 1883. Robert Koch's postulates, published in 1890, are a set of criteria that establish whether a particular organism is the cause of a particular disease.Today, Koch's postulates are taught in high school and college classrooms as a demonstration of the rigor and legitimacy of clinical microbiology.

The son of a mining engineer, he astounded his parents at the age of five by telling them that he had, with the aid of the newspapers, taught himself to read, a feat which foreshadowed the intelligence and methodical persistence which were to be so characteristic of him in later life. In 1881, he urged for the sterilization of surgical instruments using heat. He was a German general practitioner and a famous microbiologist.
