Study Notes
Introduction to Microbiology
- Microbiology (Micro = small, bios = life, logos = science) is the study of microscopic organisms (like viruses, bacteria, archaea, fungi, protozoa, and algae).
- Some microscopic organisms (like certain fungi and algae) are visible to the naked eye.
- Microorganisms are found in all environments and associated with all multicellular organisms.
- Microorganisms play critical roles in the human body, like recycling in the intestines.
- Many microorganisms are vital for life on earth.
- Humans have exploited some microorganisms for products (antibiotics, food).
Microorganisms and Human Health
- Public perception often focuses on harmful microorganisms (infections, plagues).
- In reality, only a small fraction of known microbial species cause human disease.
- Pathogens are the disease-causing microbes.
- Medical microbiology integrates various fields like immunology, virology, bacteriology, mycology, parasitology.
- Focuses on the causes of infectious diseases and host reactions to pathogens.
Infectious Diseases and Modern Medicine
- The advent of antibiotics and vaccines has lessened the fear of many infectious diseases.
- New pathogens are constantly emerging and old ones may develop resistance.
- Infectious diseases like AIDS and rabies continue to pose challenges and require ongoing research.
- Microbiology is crucial for diagnosis, treatment, and prevention of infectious diseases.
