The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can cause disease. These small organisms, which are too small to be seen without magnification, invade animals, plants , and even bacteria .
This began the path to germ specificity within the theory. [49] Louis Pasteur's contemporary Robert Koch devoted much of his scientific study to discovering certain pathogens and connecting them to specific diseases. These scientists were often in competition with one another and so the Koch-Pasteur rivalry is a well-known part of germ theory's ...
The history of public health in the United states studies the US history of public health roles of the medical and nursing professions; scientific research; municipal sanitation; the agencies of local, state and federal governments; and private philanthropy. It looks at pandemics and epidemics and relevant responses with special attention to ...
Robert Hermann Koch (11 December 1843 – 27 May 1910) was a German physician who developed Koch's postulates. [1]Koch's postulates (/ k ɒ x / KOKH) [2] are four criteria designed to establish a causal relationship between a microbe and a disease.
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.
The Jesuit Athanasius Kircher (1602–1680) first proposed that living beings enter and exist in the blood (a precursor of germ theory). The Augustinian Gregor Mendel (1822–1884) developed theories on genetics for the first time. As Catholicism became a global religion, the Catholic orders and religious and lay people established health care ...
According to germ theory, infectious diseases are caused by the presence of pathogenic microorganisms present within the physical body. Previously, disease was thought to be caused by miasma, or bad air, and while microorganisms had been discovered, they were not known to cause disease. Towards the end of the 19th century, germ theory helped ...
Following the discoveries by Louis Pasteur and others which lead to the Germ Theory, plus other technologies, the role of the environment was dominated by infection control and technological advances. Starting in the 1960s, healing environments have been linked with evidence-based design (EBD), giving the concept a strong scientific base. While ...
