Study Notes

Introduction to Bacteria

  • Bacteria are unicellular organisms classified as prokaryotes, meaning they lack a true nucleus and certain organelles.
  • These microorganisms are metabolically active and reproduce through binary fission, a simple division process.
  • Bacteria are significant in medicine, being a primary cause of various diseases.
  • While they may appear simple, bacteria are actually complex and highly adaptable life forms.
  • Bacteria thrive in diverse environments, existing in massive numbers both in and on other organisms and in various habitats.
  • Generally, bacteria can be categorized as harmful or beneficial; most play vital roles in supporting other life forms and are integral to industrial and medicinal applications.

Classification of Bacteria

  • Classification hinges on several factors:
    • Shape of the bacteria (e.g., cocci, bacilli, spirilla).
    • Composition of the cell wall (e.g., Gram-positive vs. Gram-negative).
    • Mode of respiration (aerobic vs. anaerobic).
    • Mode of nutrition (autotrophic vs. heterotrophic).
