Introduction to Microbiology
• The study of microscopic organisms
• Your Name / School / Date

What is Microbiology?
• • Study of microorganisms too small to see
with the naked eye
• • Examples: Bacteria, viruses, fungi, protozoa,
algae
• • Importance in medicine, environment, and
industry

History of Microbiology
• • Antonie van Leeuwenhoek: First observed
microorganisms
• • Louis Pasteur: Germ theory of disease
• • Robert Koch: Linked microbes to specific
diseases

Major Branches of Microbiology
• • Bacteriology – study of bacteria
• • Virology – study of viruses
• • Mycology – study of fungi
• • Parasitology – study of parasites
• • Immunology – study of immune system

Types of Microorganisms
• • Bacteria: Prokaryotic, diverse
• • Viruses: Require host to reproduce
• • Fungi: Yeasts, molds
• • Protozoa: Animal-like protists
• • Algae: Photosynthetic protists

Beneficial Roles of Microorganisms
• • Decomposition & nutrient cycling
• • Antibiotics & vitamin production
• • Fermentation (e.g., bread, yogurt)
• • Bioremediation

Harmful Microorganisms
• • Cause diseases (e.g., TB, flu, COVID-19)
• • Spoil food & water
• • Bioterrorism threats

Microbiology in Medicine
• • Vaccines
• • Antibiotics
• • Diagnosing & treating infections
• • Microbiome research

Tools Used in Microbiology
• • Microscopes (light, electron)
• • Staining techniques
• • Culture media
• • PCR & genetic tools

Conclusion
• • Microbiology is vital in health, science, and
the environment
• • Research continues to reveal new
applications
