Study Notes
Microbiology Definition and History
- Microbiology studies microorganisms, which include bacteria, archaea, algae, fungi, protozoa, and viruses.
- Anton Van Leeuwenhoek is recognized as the Father of Microbiology; he first observed live microorganisms using a simple microscope, achieving up to 300x magnification.
- He coined the term "animalcules" and documented his findings in letters to the Royal Society of London.
Divisions of Microbiology
- Bacteriology: The study of bacteria.
- Mycology: The study of fungi.
- Phycology: The study of algae.
- Protozoology: The study of protozoa.
- Virology: The study of viruses.
Early Theories of Origin of Life
- Spontaneous Generation: An early belief that life could arise from non-living matter through vital forces.
- Biogenesis: The theory that living things arise only from other living things, countering spontaneous generation.
Key Historical Figures
- Roger Bacon: Suggestive theorist on diseases being caused by invisible organisms.
- Francisco Redi: Opposed spontaneous generation through experiments on maggots and decaying meat.
- John Needham: Claimed microbes developed spontaneously from decaying fluids.
- Lazzaro Spallanzani: Believed microorganisms entered Needham's solutions post-boiling.
- Louis Pasteur: Disproved the theory of spontaneous generation and established the Germ Theory of Disease; developed pasteurization and fermentation techniques.
Modern Advances in Microbiology
- Joseph Lister: Introduced aseptic techniques in medical settings, preventing infections through disinfection and sterilization.
- Oliver Wendell Holmes: Observed higher infection rates in home births, prompting discussions on cleanliness.
- Ignaz Semmelweis: Linked maternal infections to physicians' lack of hygiene after performing autopsies.
Specializations within Microbiology
- Bacteriology: Focuses on the analysis and characterization of bacteria.
- Mycology: Studies various fungi, including their ecology and usage.
- Parasitology: Investigates protozoa and parasitic worms and their impact on hosts.
- Immunology: Explores the immune responses to pathogens.
- Virology: Covers the structure, classification, and effects of viruses on hosts.
