Microbiology: Diversity and Sub-disciplines

Overview

• Microbiology is diverse, impacting many fields:
  • Medicine
  • Agriculture
  • Food science
  • Ecology
  • Genetics
  • Biochemistry
  • Molecular biology
• Molecular and genomic methods have led to a second golden age of microbiology.
  • DNA manipulation of microorganisms is central to studying their natural relationships.

Genomic Analysis

• Involves determining the base sequence of genes.
• Defines functions and regulation of genes, forming biological systems.
