Germ theory is the theory that microorganisms are the cause of many diseases. considered one of the great breakthroughs of modern medicine, germ theory has led to improvements such as antibiotics, sterilization and hygienic practices, and the creation of vaccines. he is now broadly regarded as the father of modern microbiology. Louis pasteur (/ ˈ l uː i p æ ˈ s t ɜːr /, french: [lwi pastœʁ]; december 27, 1822 september 28, 1895) was a french biologist, microbiologist and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. he is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved. Sadly, this theory was accepted for hundreds of years by both commoners and royalty. it wasn’t until louis pasteur came along and proposed the germ theory of disease that the fields of modern microbiology and medicine were born. pasteur proved that “bad air” wasn’t the source of disease, but rather that microorganisms were the cause of. The germ theory of disease states that certain diseases are caused by specific germs or infectious agents. in the 1800s, this idea was not widely accepted, and it took a series of experiments and hard work for pasteur to prove that air contains infinitely small living organisms, and that these organisms are responsible for diseases.

The german physician robert koch (december 11, 1843 — may 27, 1910) is considered the father of modern bacteriology for his work demonstrating that specific microbes are responsible for causing specific diseases. koch discovered the life cycle of the bacteria responsible for anthrax and identified the bacteria that cause tuberculosis and cholera. Biomedicine and health: the germtheory of diseaseintroductionaccording to the modern germ theory of disease, infectious diseases are caused by the presence of pathogenic microorganisms within the body. in other words, the germ is that which gives rise to the development of disease. today, in popular usage, the word “germ” generally refers to a pathogenic microorganism, but the term is.

This was known as the germ theory of disease. although he never tested the theory, pasteur suggested that a disease might be controlled by exposing the wound to germ-killing chemicals. in 1864, while working at glasgow university as professor of surgery, lister was introduced to pasteur’s germ theory of disease, and he decided to apply it to. The predominant theory until germ theory of disease was eventually accepted in the 19th century was termed “miasma theory”, meaning “pollution” or “bad air”. miasma theory stipulated that disease originated from the decomposition of organic matter, causing a noxious vapor harboring disease-causing agents.

Koch’s “one microbe, one disease” concept was the culmination of the 19th century’s paradigm shift away from miasma theory and toward the germ theory of disease. koch’s postulates are discussed more thoroughly in how pathogens cause disease. This theory states that some infectious diseases are caused by tiny microorganisms invading a host organism. this definition sounds pretty kindergarten today, but this was a dramatic shift from.
