  • Listen to ME, take smart notes

  • Powerpoints will be posted following class

  • Stuff

  • Schedules may change, more likely in lab

  • Alteration in points for Lab assignments

  • Don’t be a stranger.

  • Please no cell phone use or ringing in class.


  • Grading

  • Four regular exams, 100 points each

  • Final (fifth) Exam, 100 points. Comprehensive final optional.

Microbiology definitions
Microbiology: Definitions

  • Chapter 1 in text

  • Microbiology: study of living things too small to be seen w/o a microscope.

    • What’s life?

      • Highly organized, self replicating, self-adjusting, capable of evolving, can obtain energy

    • Are all microbes that small?

      • Epulopiscium and Thiomargarita: visibly large bacteria


Classification of microbes
Classification of Microbes

  • Three domains

    • Eubacteria: prokaryotic cell structure

    • Archaebacteria: prokaryotes, but different

    • Eukaryotes: 4 kingdoms

      • Plants, animals, fungi, and protists.

  • What are microbiologists interested in?

    • Eubacteria and archaebacteria for sure.

    • Eukaryotes like fungi and protists

    • Animals (parasitic worms) but not really plants.

    • What’s missing?

    • VIRUSES!


Divisions of microbiology
Divisions of Microbiology

  • By critter type:

    • Bacteriology, virology, mycology

    • Parasitology (includes protozoa, fungi, worms)

  • Other divisions:

    • Pathogenic microbiology, Immunology, molecular biology, microbial ecology

    • Applied microbiology: water treatment, natural products, food microbiology, environmental microbiology


History ancient knowledge
History: Ancient knowledge

  • Recognition of Immunity:

    • Variolation and protection from infection

      • Intentional contact with minor form of smallpox

    • Edward Jenner and cowpox

      • Milkmaids catch cowpox, seem to be immune to smallpox.

  • Contagion: disease can be spread by contact.

    • Exclusion of lepers; burning of plague victims

    • Catapulting of disease victims into castles during seige

History continued
History continued

  • Microbiology as a biological science

    • Robert Hooke, 1665, discovery of cells

    • Antony van Leeuwenhoek, father of microbiology

      • Dutch amateur lens grinder

      • First person to see microbes, late 1600s

    • Mid 1800s, microbes taken more seriously and studied using the scientific method

History the golden age
History: the Golden Age

  • From about 1850 to start of 20th century

    • Pasteur lays to rest the idea of spontaneous generation

    • Pasteur shows fermentation associated with life

      • Prevents unwanted fermentation by Pasteurization

      • Saves the French wine industry

    • Germ theory of disease: sicknesses caused by microbes

    • Robert Koch: lab techniques like agar, staining

      • Koch’s postulates: how to link a microbe w/ a disease.

    • Semmelweis and handwashing

    • Lister and aseptic surgery

    • Ehrlich and antimicrobials


20 th century microbiology
20th Century Microbiology

  • Molecular biology

    • Use of microbes as model systems for study

    • Study of DNA, proteins synthesis

    • Tools and processes for recombinant DNA

  • Applied microbiology

    • Food industry

    • Water and sewage treatment

    • Bioremediation

  • Medicine

    • Emerging diseases; antibiotic resistance


    • Why Study Microbes?

    • Major impact on health

      • Responsible for disease in humans, animals, plants

    • Major impact on environment

      • Major decomposers

      • Nutrient cycling, elemental cycling

    • Microbes are talented

      • Live under extreme conditions

      • Protect against disease

      • Eat oil, toxic waste (bioremediation)

      • Make plastic

      • Spoil food, make food

      • Use light, produce light
