Germ theory is the theory that reveals which microorganism causes which disease. This theory was developed by German scientist Robert Koch in the late 19th century while he was experimenting with anthrax, a bacterial infection. In fact, it was through this theory that Koch was able to determine that bacteria were the cause of common diseases, such as tuberculosis and cholera. He was also responsible for the discovery that antibodies can help in the destruction of bacteria, which, in turn can boost immunity. However, it was in the hands of the French chemist named Louis Pasteur that the world got familiar with the modern germ theory in the late 1890s. This was a result of his home experiment with food which revealed that even the invisible microorganisms had the power to contaminate it. Find out with the help of this quiz, how much do you really know about germ theory.
Q1) Louis Pasteur based the germ theory on which other existent theory?
Q2) Which experiment proved to be a vital evidence in support of the germ theory of illness?
Q3) What is John Snow, a pioneer in the field of germ theory popular known as?
Q4) How is Ignaz Semmelweis related to germ theory?
Q5) Who was the first one to practically apply germ theory to medical science?
ANSWERS:
Q1. (b)
Louis Pasteur based the germ theory on another existent theory called Contagion theory. By blending both the theories, Pasteur declared that diseases are transmitted through air, water as well as dirt.
Q2. (a)
Pasteurization experiment proved to be a vital evidence in support of the germ theory of illness. This experiment demonstrates that air particles and not air itself caused deterioration in health.
Q3. (b)
John Snow, a pioneer in the field of germ theory is popular known as the father of modern Epidemiology. He was conferred this recognition right after on cholera. Snow was also the pioneer in the development of anaesthesia and medical hygiene in England.
Q4. (c)
Ignaz Semmelweis is related to germ theory for his pioneering work in the development of antiseptics. This Hungarian physician and scientist invented antiseptics while studying hand disinfection in obstetrical clinics.
Q5. (d)
Joseph Lister was the first one to practically apply germ theory to medical science. This happened when during a surgery, he discovered a way to avoid infection in open wounds.
