    Study Notes

    Microbiology

    • The study of microorganisms that are too small to be seen with the naked eye.

    Bacterial Arrangement

    • Staphylo: Bunches or clusters of cells, resembling grapes.
    • Strepto: Chains of cells.
    • Diplo: Pairs of cells.
    • Tetrad: Groups of four cells
    • Sarcinae: Groups of eight cells.

    Bacterial Morphology

    • Bacteria are single-celled organisms.
    • They have diverse shapes, including:
      • Bacilli: Rod-shaped
      • Cocci: Spherical
      • Spirilla: Spiral or helical

    Nomenclature

    • Carolus Linnaeus established the system of scientific nomenclature in 1739.
    • The basic taxonomic group is the species.
    • Organisms are given two names: Genus + specific epithet (species)
    • Names are italicized or underlined, with the genus capitalized.
    • Names are typically descriptive or honor a scientist.
