Louis Pasteur and Robert Koch - Case Study ExampleBorn in 1822 in France, Pasteurs work in the field of microbiology is immensely recognise and encountered in our daily lives. Among his popular works include the invention of pasteurisation process, the discovery of the germ-disease relationship, as well as the invention of the rage vaccine. Contributions He observed the role of pasteurization while at the university where he was a chemistry professor. He was approached to establish the course of souring in vino. In the process Pasteur established that the reason behind the souring of wine can be think to that of souring in milk, which is as a result of bacterium contamination. He established that the bacterium produced an sour that was responsible for the souring of the wine. He went further to establish that, heating the wine gently to temperatures around 60o C for at least 30 minutes led to the destruction of the bacterium, which subsequently prevented further souring of win e (Krasner, 1995). He described the process of souring as fermentation and the process of heating the wine to temperature levels abundant to kill the bacterium as pasteurization. The process is nowadays widely applicable in the many nutrient production industries and even locally in many households to kill disease do bacteria as well as im demo shelf life of various food products as well as in hospitals to prevent germ re-infection (Engelkirk & Engelkirk, 2010). He is also recognized for his role in the discovery of attenuation. He discovered that rabies future rabies infection could also be prevented finished vaccine which entailed injecting civilised weakened rabies bacteria into a rabbit and realized that after injection of the rabbits with virulent inoculant, the rabbits did non show any sign of infection. This vaccine has been enhanced and widely used in the prevention of rabies in human and dogs. In the germ theory, he discovered that specific microbes cause specific mor bific disease. Robert Koch Robert Koch, born in 1843 in Germany, is yet another infamous personality worth to recognize in the field of microbiology and human health. He is purported to have made a tremendous contribution in these fields. In particular according to Krasner (1995), Koch further enhanced the previous job of Pasteur especially the germ theory. He provided prove that the specific microbes were the cause of certain disease, for instance he showed that anthrax bacillus was the main cause of anthrax. This was through the conduction of a series of steps that became popularly known as the Kochs Postulates. The postulates provided a rule of thumb that would allow for the isolation and subsequent analysis of the specific microbes that cause specific diseases. He also discovered that the Anthrax Bacillus just like many spore-producing microbes, were capable of resisting adverse conditions, which was fundamental in judgment the life cycles of the disease as well as the correct mechanism of prevention of the disease. Furthermore, Koch is also recognized for inventing fixation, staining techniques as well photographing of bacteria which paved way for further studies on disease causing bacteria. Engelkirk and Engelkirk (2010) further contends that Koch was also the key personnel behind the discovery of the bacterium that causes tuberculosis, the M. tuberculosis, and Vibrio epidemic cholera that causes cholera which are some of the most common and dangerous disease. This enhanced
