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).
