Study Notes

Human and Microorganism Interactions

  • Humans have been using microorganisms for thousands of years to improve life and shape civilizations, including using yeast to make bread, wine, and cheese.
  • Early Egyptians used moldy bread to treat wounds before penicillin was discovered.
  • Biotechnology is a modern method that manipulates microorganisms to create products like insulin.
  • Humans extract human insulin protein to produce the hormone needed for injections via genetic engineering.

Microorganisms and Human Disease

  • Microorganisms cause numerous human diseases.
  • The difference in disease rates between developed and developing nations is an important consideration.
  • Microbiologists study microbes' structure, function, growth, physiology, genetics, taxonomy, evolutionary history, interactions with environments, and interactions with humans.
  • Public health microbiology and epidemiology monitor and control the spread of diseases within communities.
  • Examples of public health agencies include the CDC and the WHO.
  • Historical examples of microbiologists include David Bruce who discovered the microorganism that causes Malta fever.
  • Infectious diseases are caused by pathogens, agents such as viruses, bacteria, fungi, parasites, and prions, which cause harm.
  • Example pathogens include the microorganism causing malaria, which is transmitted by mosquitoes.

Modern Applications of Microbiology

  • Industrial microbiology safeguards food and water, creating amino acids, drugs, enzymes, vitamins, and more.
  • The process also uses microbes to create enzymes and vitamins.
  • Agricultural microbiology studies microbe-plant relationships.
  • Environmental microbiology investigates how microbes impact diverse earth environments.

Taxonomy

  • Taxonomy classifies organisms using a hierarchical system.
  • The Linnaean system, named after Carl Linnaeus, uses broader and broader groups to classify organisms.
  • The Linnaean system is used to classify organisms from broader groups like domain to the most specific category like species through genus, family, order, class, phylum.
  • Example classifications include using the species Canis lupus familiaris to refer to a domesticated dog, in which Canis being a genus and lupus a subspecies.
