Document Summary
Lectures focus on important historical events that led to the development of microbiology as a scientific discipline and end with general areas that have developed to the present time. Particularly important is how knowledge of microbiology has almost doubled the average life span in the industrialized world over the last century. Antonie van leeuwenhoek (1632-1723) constructed microscopes and was the first person to observe and describe bacteria and other microorganisms accurately (footnote at end) No growth was observed because dust particles carrying organisms did not reach the medium, instead they were trapped in the neck of the flask. If the necks were broken, dust would settle and the organisms would grow. In this way pasteur disproved the theory of spontaneous generation. The recognition of the microbial role in disease and culturing of bacteria: robert koch (1843-1910) established the relationship between bacillus anthracis and anthrax.
