Germ Theory Of Disease Case Study

Decent Essays
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

    For this experiment, unknown sample #12 was used. The first step in identifying any unknown bacterium is to grow a culture on a nutrient agar plate. This bacterium was also plated on a MAC plate, which is both selective for gram-negative bacteria and differential as well. On the NA plate, bright red colonies were present; on the MAC plate there was bacterial growth as well, but no color change was observed. This lack of color change on the MAC plate indicated that the bacteria did not ferment lactose.…

    Also apply in food and medicine industry, research about the origin and relation between organism and so on. This study was conducted using techniques that have been learned so far in microbiology laboratory. Organisms are divided into two domains: prokaryotes and eukaryotes, which further diverted in three other domains consists of Bacteria, Archaea and Eukarya , there are major different between these two where prokaryotes are much simpler internal structures, circular DNA, lack nucleus and any membrane bounded organelles and in general smaller in size. Bacteria and Archaea fall into this category, however despite they sharing same characteristics, Archaea are in fact closely relate to Eukarya than Bacteria. The domain bacteria is diverted with various prokaryotes, all pathogen fall under this category but not all bacteria are pathogenic (Madigan et.al…

    In the four-week long experiment conducted in the Bio 13 Lab, we were able to conduct a genetic analysis of the yeast S. cerevisiae, particularly investigating the inheritance and linkage of three genes: HIS4, LEU2, and LYS2. In week one, a suspension of spores was received and aliquots of the suspension were plates onto two YPD plates. After a week of yeast growth, haploid spore clones were carefully picked from the plates by sterile toothpicks and used to make patches on a new YPD plate, the master plate. In week three, the master plate was replicated onto three dropout plates: -His, -Leu, and -Lys. In the final week, the growth of the patches on the dropout plates were analyzed and class data was collected in order to conduct calculations for…

    Something had to be done. By now scientists understood that germs cause disease and thanks to Koch they knew how to perform tests to discover which germs caused a particular disease. Or so they reckoned, in 1894 a team of scientists from Robert Koch’s Institute went to Hong-Kong to find the plague germ. They were led by renowned scientist Shibasburo Kitasto. But there was another scientist in the field, Swiss born Alexandre Yersin (1863-1943) who had worked for Louis Pasteur and had since been travelling and making maps in Vietnam.…

    Using a wire loop, a small sample of the unknown test tube was plated on a nutrient agar using the streak method . The unknown test tube was then placed in a refrigerator to slow down any continued growth. The nutrient agar was labeled “VB TR1” and was placed in an incubator for 48 hours at 37 degrees Celsius. Following this procedure, I started to do research on microorganisms that presented the same type of symptoms (diarrhea and nauseous). After 48 hours, the plate was observed.…

    The Germ Theory was proposed, developed, and proved in the mid 1800s, at about the time of the Civil War. At first, not all doctors and scientists believed in the Germ Theory when they first were introduced to the idea, but shortly after the Civil War, due to the amount of infection during the war and the exploration of it the came after, they were convinced that many diseases are caused by the presence and actions of microorganisms inside the body of people. This proposition revolutionized the medical field because it made people aware that germs cause diseases, how germs related to home hygiene such as cooking, plumbing, and heating, and how germs were spread from one person to…

    The research enabled by these cells led to many medical advancements. The first of these was the ability to test vaccines on these cells. When it was discovered that the cells could be infected by various viruses, such as measles and polio, it paved the way for the research of various aspects of the virus. Scientists were now able to know how each one of these viruses entered cells and spread, giving them a greater understanding about prevention and treatment of the virus. Just as important, the scientists could also develop and test a vaccine…

    The lab instructor issued out a test tube labeled with letter ‘I’, which consisted of two unknown bacteria, Gram-positive or Gram-negative that were streaked from a pure culture. Sterile techniques were followed while performing precise instructions as stated in the referenced Laboratory Manual. Example 1: The first procedure performed was done by isolating a pure culture from the mixture onto a solid Trypticase soy agar (TSA) media. Sterile technique was done by flaming the loop until it turned red to ensure that there were no current bacteria on the loop avoiding contamination followed by rapidly flaming the neck of the test tube to prevent the entry and contamination of unwanted microbes.…

    The results were that in the plate labeled +pGLO LB/amp, colonies will grow and survive. In the plate labeled +pGLO with amp/LB/ara, bacteria will grow and glow green under UV light due to the addition of arabinose. In the plate labeled -pGLO with LB/amp, no bacteria will be able to grow due to the bacteria not being resistant to the antibiotic. Finally, in the last plate labeled -pGLO with LB and no amp, will host a lawn of colony due to no limiting factors. This results conformed my hypothesizes.…
