  1. prokaryotes
    organism without a true nucleus

    lack organelles

    • 10x smaller then eukaryotics
    • \
    • Archaebacteria
    • & Bacteria
  2. eukaryotes
    organisms with a true nucleus

    • Protists,
    • Fungi, Plants, Animals
  3. ubiquitous
    • occur in large numbers
    • lives in places many other organisms cannot
    • most are beneficial some harmful
  4. robert hooke
    earliest record of microbes work
  5. antonie van leeuwenhoek
    created the first single lens microscope

    known as the father of bacteriology and protozoology
  6. lois pasteur
    • developed s-shaped flack
    • discovery of pathogens and the germ theory diesase
    • fermentation and pasteurization
  7. pasteurization
    application of a high heat for a short time is called pasteurization
  8. joseph lister
    • •1860s: Joseph Lister used a chemical
    • disinfectant to prevent surgical wound infections after looking at Pasteur’s work. Introduced Aseptic Techniques.
    • (Sepsis – the presence of pathogenic organisms)
  9. robert koch
    • •1876: Robert Koch provided proof that a
    • bacterium causes anthrax and provided the experimental steps, Koch’s postulates, used to prove that a specific
    • microbe causes a specific disease.
  10. Microbial nomenclature-
    naming microorganism
  11. taxonomy
    classifying living things
  12. Identification
    • •discovering
    • and recording the traits of organisms so they can be named and classified

    • •Levels of Classification: 3
    • Domains:
    • Archaea, Eubacteria, Eukarya.
    • 6Kingdoms:
    • Archaeabacteria, Bacteria, Protists, Fungi,
    • Plants, Animals
  13. binomial system of nomenclature
    • The generic (genus) name followed by the
    • species name

    • Generic part is capitalized, species is
    • lowercase

    • Both are italicized or underlined if
    • italics aren’t available

    • Staphylococcus aureus,
    • Homo sapien, T. rex.
  14. Phylogeny-
    the degree of relatedness between groups of living things based on ancestry/evolution.

    • •Phylogeny
    • usually represented by a tree- showing the divergent nature of evolution
  15. evolution
    • hereditary information in living things changes gradually through time; these changes
    • result in structural and functional changes through many generations
