Introduction to Microbiology

Microbiology Overview

• Microbiology is the scientific study of microorganisms, which are organisms that cannot be seen without a microscope due to their small size.
• The term 'micro' indicates something too small for naked-eye observation, while 'bio' refers to life and 'logy' means study.

Types of Microorganisms

• Bacteria: Single-celled organisms that can be found in various environments. They play crucial roles in processes such as decomposition and fermentation.
• Viruses: Non-cellular entities that require a host cell to replicate. They are responsible for various diseases affecting living organisms.
• Fungi: A diverse group of organisms including yeasts and molds, involved in decomposition and can form beneficial relationships with plants.
• Parasites:
  • Protozoa: Single-celled eukaryotic organisms, often causing diseases in humans and animals.
  • Helminthes: Multicellular parasitic worms that can infect hosts and lead to various health issues.
• Algae: Photosynthetic organisms found in aquatic environments, contributing significantly to oxygen production and serving as a food source in ecosystems.

Significance of Microorganisms

• Microorganisms are ubiquitous, meaning they are present almost everywhere on Earth, including extreme environments.
• They play vital roles in ecological balance, human health, and biotechnology.
