Germ Theory Of Disease Case Study

The validation of the germ theory of disease was one of the turning points in microbiology and science, as a whole. Doctors and scientists were skeptical about the idea of tiny microorganisms, that aren 't visible to the naked eye, being able to have such adverse effects on our health and the world around us. By validating the germ theory of disease, Koch was actually able to put an end to the general public 's positive view on spontaneous generation of bacteria with the experiments he conducted using Bacillus anthracis . His experiment essentially proved that a specific bacterium caused a specific disease. This revolutionized the scientific school of thought and a new branch of science was born. People were beginning to realize that studying …show more content…
Koch quickly determined that his method of growing bacteria in aqeuous solution was not the best way. The development of solid culture media was significant in the sense that scientists and researchers are now able to conduct work on various microorganisms, on transparent plaques, and at different temperatures while maintaining a pure culture. Before this discovery, Koch was believed to be using solid food sources such as potato slices, but was unable to continue doing this as not all microorganisms reacted the same way to the nutrients and therefore did not grow in a pure culture . This relates to this particular course because it shows that all microorganisms are different and there is no one "fix-all" solution to studying them. It exemplifies the importance of picking the correct culture media, and later on, staining method, for the microorganism we wish to isolate. This discovery helped solidify my knowledge in the diversity of …show more content…
This lead to the idea that enrichment of a culture can optimize the growth of a bacteria that we wish to isolate. This work also lead to the understanding of nitrogen fixation and explained the occurrence of soil fertilization with legumes . This was a big advancement for microbiology and the agriculture industry. This relates to many modules in our class, notably modules 3 and 4. We can better understand the function of certain cells and their role in the bacteria 's cell body as well as have a greater understanding of the growth of microorganisms.
The discovery of bacteriophages was something like turning a new chapter in the book of science. It was an interesting discovery because the idea of a bacteria "eating" or decomposing another bacteria was not thought of in the past. This led to the idea of introducing bacteriophages to kill bacteria. Over the past few years, the FDA has even approved the use of bacteriophage based drugs to treat raw meats . This relates to Module 6 when we 'll start learning more about bacteria and their
