Study Notes
Introduction to Microbiology
- Microbiology is the study of microorganisms, including bacteria, viruses, fungi, and parasites.
- Microorganisms play significant roles in the environment and human health, with both positive and negative impacts.
Types of Microorganisms
- Bacteria are single-celled organisms classified by their shape (spherical, rod-shaped, spiral) and oxygen requirements (aerobic, anaerobic).
- Viruses are obligate intracellular parasites that are smaller than bacteria and rely on host cells for replication.
- Fungi include yeasts and molds, some beneficial and some detrimental.
- Parasites live at the expense of other organisms and can be multicellular.
Medical Importance
- Microorganisms cause infectious diseases, which can be transmitted through various means.
- Bacteria cause infections, while viruses cause diseases.
- Antibiotics treat bacterial infections, but the emergence of antibiotic resistance poses a significant health threat globally.
Applications of Microorganisms
- Microorganisms are used in industrial applications, such as drug production and food fermentation.
- They play vital roles in scientific research, including genetic engineering and disease research.
