Some unique characteristics about microbes are that they are ubiquitous, dominant, diverse, and free living. Since the experiments of the great scientists such as Pasteur and Koch, the world of microbiology has taken great strides in understanding the impact that microbes have on the world, whether beneficial or destructive. A period from 1857 to 1914 was called “The Golden Age of Microbiology” which marked the beginning of rapid advances and discoveries such as vaccines for disease to fermentation and pasteurization. This period came to be one of the most influential and ever-changing sciences in the world today. If it wasn’t for the first experiments in the field, we would not know that microorganisms are the main cause of most diseases in the world. We all live in a world filled with microbes from birth to death and we have numerous microorganisms on our bodies as well as inside of our bodies. These microorganisms are known as normal microbiota or normal flora. These microorganisms benefit us in that it prevents us from being sick all the time.
