Bacteriology

Bacteriology is a branch or discipline of science that studies different characteristics of bacteria and their association with other organisms or disciplines.

  • Over the years, the discipline of bacteriology has evolved from the microbiological tests performed only by physicians, the application of the germ theory of disease and economic concerns relating to the spoilage of foods and wine to the use of bacteria to simpler forms of laboratory tests and the production of new nutritious food and antibiotics.
  • The study of bacteria began with the discovery of the microscope and was mostly limited to experts and scientists of that time.
  • The initial advances in pathogenic bacteriology began with the identification and characterization of bacteria associated with specific diseases.
  • Nowadays, however, bacteriology is used in various other fields like food, pharmaceuticals, agriculture, and the environment.
  • Significant advances made in bacteriology over the last century have resulted in the development of many useful vaccines like pneumococcal polysaccharide vaccine, diphtheria toxoid as well as antibiotics.
  • At present, most bacterial diseases in humans and their infectious agents have been identified, although significant variants continue to evolve and sometimes emerge.
  • Studies made in bacteriology have also allowed the use of gene recombination technology in bacteria to produce improved bacterial strains that can then be used in various areas.
  • The importance of bacteriology continues to grow throughout the years as many diseases and disorders associated with almost all living beings are caused by bacteria.
  • Studies of non-pathogenic bacteria that exist in a symbiotic relationship with plants and animals are even beneficial to said organisms.
  • The identification and classification of bacteria into different groups have allowed for a convenient way of studying these bacteria and the formation of a separate branch, systemic bacteriology, that deals with taxonomy.
  • Besides, bacteriological studies, subsequently, have also been divided into different areas like soil bacteriology, public-health bacteriology, industrial bacteriology, etc.
  • Bacteriological studies have been the focal point for disease diagnosis and treatment, and their importance continues to grow with the emergence of new bacteria and associated diseases.
