Study Notes
Introduction to Microbiology and Parasitology
- Microbiology studies microscopic living organisms and certain non-living entities.
- Living microbes are cellular microorganisms: includes bacteria, archaea, certain algae, protozoa, and some fungi.
- Non-living microbes are acellular: includes viroids, prions, and viruses.
Leading Causes of Morbidity
- Acute lower respiratory tract infections and pneumonia rank highest.
- Other significant causes: bronchitis, acute watery diarrhea, influenza, hypertension, tuberculosis, heart diseases, malaria, chicken pox, and dengue fever.
Leading Causes of Mortality
- Heart diseases and vascular system diseases are the leading causes of death.
- Malignant neoplasm, pneumonia, accidents, tuberculosis, chronic lower respiratory diseases, diabetes mellitus, perinatal period conditions, nephritis, and nephrotic syndrome also contribute significantly.
Pathogens and Nonpathogens
- Pathogens are disease-causing microbes, while nonpathogens do not cause diseases.
- Indigenous microbiota refers to microbes residing on and within the human body.
- Opportunistic pathogens can cause disease under certain conditions but are generally harmless.
Role of Microbes in Ecosystems
- Algae and bacteria play crucial roles in food chains, serving as food for small animals.
- Intestinal microbes facilitate digestion and produce beneficial substances for hosts.
Importance of Studying Microbiology
- Microbes are vital for industries like food, beverage, chemicals, antibiotics, and genetic engineering.
- Photosynthetic organisms like cyanobacteria produce significant amounts of atmospheric oxygen.
- Microorganisms decompose organic matter and waste, aiding nutrient cycling.
- Biotechnology uses living organisms for product modification or production.
