Microbiology is the study of organisms that usually require the aid of a microscope in order to be seen. Micro-organisms include viruses, bacteria, archaea bacteria, algae, fungi, and protozoa. Microbiologists seek to understand the interactions between these organisms and components of our biosphere. Many micro-organisms are essential for life, as we know it, to exist on earth. Many of these organisms produce useful biologically active products, such as enzymes and antibiotics. A small number of them cause diseases in plants and animals, including humans.

The study of micro-organisms has led to many important discoveries concerning:

  • the complexities, universality and mechanism of expression of the genetic code;
  • the transfer of genetic information between species and modulation of the gene pool;
  • the mechanism of antigen-antibody reactions and cellular immunity;
  • the synthesis of proteins, nucleic acids and other cellular constituents;
  • the structure, function and biogenesis of membranes; and,
  • the process of molecular and cellular differentiation.
