Exam 1 UTA Microbiology Already Graded A+
Key Figures in Microbiology and Biology
1. Microbiology: The study of small organisms, including bacteria, viruses, fungi, and parasites.
2. Hippocrates: Known as the father of western medicine; he believed that diseases were caused by
natural, not supernatural, reasons.
3. Anton van Leeuwenhoek: Known as the father of microbiology; he was the first to observe and
describe microorganisms using a microscope.
4. Louis Pasteur: Known for discovering the process of fermentation and inventing pasteurization as well
as developing vaccines for diseases like rabies and anthrax.
5. Robert Koch: Created the Koch's postulates, a method for linking specific pathogens to specific
diseases, and contributed to the development of vaccines.
6. Carl Linnaeus: Known as the father of taxonomy, he contributed to the classification of organisms into
the plant and animal kingdoms.
7. Ernst Haeckel: Expanded the tree of life to include the protists and monera kingdoms.
8. Robert Whittaker: Added the fungi kingdom to the classification system.
9. Carl Woese and George Fox: First to develop molecular techniques for phylogenetic analysis, leading
to a new understanding of the tree of life based on genetic similarities.
### Nomenclature and Taxonomy
- Nomenclature: Written as Genus Species (e.g., Escherichia coli).
, - Levels of Classification:
- Least specific to most specific: Kingdom, Phylum, Class, Order, Family, Genus, Species, Strain.
### Types of Microorganisms
- Prokaryotes:
- Bacteria: Unicellular, prokaryotic organisms with peptidoglycan in their cell walls; some are
photosynthetic.
- Archaea: Unicellular, prokaryotic organisms with pseudo-peptidoglycan cell walls that often live in
extreme environments.
- Eukaryotes:
- Algae: Unicellular or multicellular, eukaryotic organisms with cellulose cell walls.
- Protozoa: Unicellular, eukaryotic organisms without a cell wall.
- Fungi: Unicellular or multicellular, eukaryotic organisms with chitin cell walls.
- Helminths: Multicellular, eukaryotic organisms without cell walls.
- Acellular Microbes:
- Viruses: Non-living infectious agents that can only replicate inside living hosts.
- Prions: Infectious proteins that cause neurodegenerative diseases.
### Principles of Wave Physics
- Wavelength: The length between peaks of a wave.
- Amplitude: The height of peaks or depth of troughs of a wave.
- Frequency: The rate at which peaks occur over time.
- Relationship Between Wavelength and Frequency:
- As wavelength increases, frequency decreases.
