Study Notes
Introduction to Microbiology
- Microbiology is the study of organisms too small to be seen with the naked eye, including bacteria, archaea, fungi, protozoa, algae, and viruses
- Microbes are found in three domains of life: Bacteria, Archaea, and Eukarya
- Bacteria are prokaryotic, single-celled organisms with no nucleus
- Archaea are prokaryotic, single-celled, and often live in extreme environments
- Eukarya are eukaryotic, have a nucleus, and membrane-bound organelles
- These domains differ in their rRNA sequences
Viruses
- Viruses are obligate parasites: non-living entities depending on host cells for replication.
- Viruses contain either RNA or DNA, but never both
- Viruses are typically smaller than bacteria
Size Comparison
- Macromolecules (1-10 nm)
- Viruses (20-300 nm)
- Bacteria & Archaea (0.1-5 µm)
- Eukaryotic cells (10-100 µm)
Taxonomy
- Taxonomy is the categorization of organisms based on shared traits
- The hierarchy includes domains, kingdoms, phyla, classes, orders, families, genera, and species
- The names of genus and species are used to uniquely identify specific organisms
