A week later, 500 people were dead. Such microorganisms can consist of bacterial, viral, fungal, or protist species. The germ theory is important because it established the cause of many diseases, which led to their prevention and treatment. All other trademarks and copyrights are the property of their respective owners. Germ theory led to the realizations that hand washing helps prevent the spread of disease, disinfectant can eliminate germs, and specific microorganisms cause specific diseases.

Germ - refers to a rapidly growing cell. Key Figures in the Development of Germ Theory. 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 germ theory of disease states that certain diseases are caused by specific germs or infectious agents.

Germ theory began when one scientist became motivated to disprove the theory of spontaneous generation. It is a highly biased list. Germ Theory and Florence Nightingale’s Environmental Theory often work together. Biogenesis, the concept signifying the emergence of living cells from the preexisting cells, is a mutually dependent factor, which offers explanation for the phenomenon of disease transmission, prediction of observable events and development of treatment strategies (Gillen, 2008). Spontaneous generation - the hypothesis that living organisms arise from nonliving matter. He developed it using his microscope and stated that ‘germs’ (microbes) caused disease and illness.

It created an everlasting impact that shifted the way scientists saw diseases and how they were caused. Pasteur’s discovery was important to the work of many other scientists and doctors. He believed that microbes causing infection were readily transferred from patients to patients, medical staff to patients and vice versa.Thus, Semmelweis suggested the use of chlorinated lime solution for handwashing to prevent the infectious disease from spreading. (Louis Pasteur did not propose germ theory until 1861.) However, over the course of her work, she came to accept the new idea of germ theory, which we still understand to be correct today.
