Study Notes
Early History of Microbiology
- Bacteria and protozoa were the first microbes to be observed by humans, with a 200-year delay in establishing a connection between microbes and infectious diseases.
- Development of microscopes, bacterial staining procedures, and techniques for culturing microorganisms in the laboratory were significant events in the early history of microbiology.
Pioneers in Microbiology
-
Robert Hooke (1665)
- Observed that plant material was composed of ‘little boxes’
- Introduced the term cell, laying the groundwork for the cell theory
- His single-lens microscope could see large cells but lacked resolution to see microbes clearly
Pioneers in Microbiology
-
Anton Van Leeuwenhoek (1670)
- Probably the first to observe live organisms using a simple microscope (single-lens)
- Father of microbiology, bacteriology, and protozoology
- Provided accurate descriptions of bacteria, protozoa, and fungi
Pioneers in Microbiology
-
Louis Pasteur
- Contributed to the foundations of microbiology
- Developed the Germ Theory, which postulates that microorganisms are in the environment and cause infectious disease
- Discovered the process of alcoholic fermentation
- Demonstrated that different types of microbes produce different fermentation products
- Developed the process of pasteurization to kill pathogens in liquids
- Discovered forms of life that could exist in the absence of oxygen
- Introduced the terms “aerobes” and “anaerobes”
- Discovered infectious agents that caused silkworm diseases
- Championed changes in hospital practices to minimize the spread of disease
- Developed vaccines to prevent chicken cholera, anthrax, and swine erysipelas
- Developed a vaccine to prevent rabies in dogs and successfully used it to treat human rabies
Pioneers in Microbiology
-
Robert Koch
- Contributed to the Germ Theory of Disease
- Proved that Anthrax Bacillus was the causative agent of Anthrax
- Developed methods of fixing, staining, and photographing bacteria
- Developed methods of cultivating bacteria on solid media
- Discovered the bacterium that causes tuberculosis (M.tuberculosis) and cholera (Vibrio cholerae)
- Worked on tuberculin, leading to the development of a skin test for diagnosing tuberculosis
