Study Notes
Techniques for Microbial Isolation
- Soil or food sample is weighed (1g) and mixed with 90ml distilled water to create a smear for microbial isolation
- Various characterization techniques are used, including morphological, physiological, biochemical, molecular, and others
Microorganisms
- Microorganisms are diverse and found in all three domains of life: Archaea, Bacteria, and Eukarya
- Archaea and bacteria are classified as prokaryotes because they lack a cellular nucleus
- Archaea differ from bacteria in evolutionary history, genetics, metabolic pathways, and cell wall and membrane composition
- Studied eukaryotes in microbiology include algae, protozoa, fungi, and helminths
- Algae are plant-like organisms that can be either unicellular or multicellular and derive energy via photosynthesis
- Protozoa are unicellular organisms with complex cell structures; most are motile
Environmental Problems
- Tourism contributes to environmental problems such as the green house effect
- Air travel and tourist activities can harm the environment
Microbiologists in Ethiopia
- Renowned microbiologists in Ethiopia have made significant contributions to the world of science
- Studying their works and research can provide valuable insights
Microbiology
- Microbiologists typically specialize in one of many subfields, but all health professionals need a solid foundation in clinical microbiology
- Viruses are acellular microorganisms that require a host to reproduce
- Helminths are multicellular parasitic worms, often studied in microbiology due to their microscopic eggs and larvae
