Study Notes
Microbiology Study Notes
- Microbiology is the study of microscopic organisms.
- Protozoa are single-celled eukaryotes.
- They are found in environments with moisture.
- Protozoa can enter a dormant stage with no water.
- Protozoa are classified by how they move (pseudopods, cilia, or flagella).
- Algae can be unicellular or multicellular.
- They use photosynthesis.
- Algae are classified by pigmentation.
- Agar is used to solidify a culture medium for microorganisms.
- Parasites are organisms that live off and cause damage to a host.
- Worms, such as flukes and tapeworms, can be parasites.
- Viruses are non-living infectious particles.
- They require a host cell to replicate.
- Spontaneous generation is the false idea that living things arise from non-living matter.
- Louis Pasteur disproved spontaneous generation using swan-necked flasks.
- Koch's postulates are used to link a specific microorganism with a specific disease.
- Etiology is the study of the cause of a disease.
- Pathogens are disease-causing agents.
- Aseptic techniques and handwashing prevent contamination in scientific procedures.
- Microbes can cause serious disease in humans, animals and plants.
- Microbial life on earth is vital for the environment.
- Antibiotics are used to treat bacterial infections.
- Microbial life affects many human activities.
- Bacteria, Archaea, and Eukarya are domains in the tree of life.
- Taxonomy involves categorizing and classifying organisms.
- Microbial classification is a critical part of Microbiology.
- Microscopy, staining, and classification methods are critical for studying microbes.
- Different microscopy techniques exist (light, electron).
- Staining methods facilitate visualization of microbes.
- Various staining techniques emphasize different aspects of microbes.
- Bacteria reproduce through binary fission.
- Microbial genetics involves studying the inheritance and transfer of genetic material.
- Bacteria can swap genes (horizontal transfer).
- Transformation involves taking up external DNA.
- Transduction utilizes viruses to transfer genetic material.
- Conjugation uses pili for cell-to-cell contact and gene transfer.
- Microbial metabolism includes various pathways (Glycolysis, Krebs Cycle).
- Fermentation can occur when oxygen is scarce and involves other electron acceptors.
- Microbial life and infection can have both positive and negative impacts on ecosystems and human life.
