LESSON ON INFECTIOUS DISEASES

For my college prep biology I class at Harlem High School, Columbia County, Georgia, I teach a unit on the agents of infectious diseases. These agents include viruses, prions, bacteria, protists and fungi.

  1. Viruses are noncellular agents of infection that are merely nucleic acid wrapped with a protein coat.
  2. Prions are proteinaceous infectious particles with neither DNA nor RNA.
  3. Bacteria are unicellular, prokaryotic organisms that are the most abundant organisms on earth.
  4. Protists are unicellular, eukaryotic organisms that are much, much larger than bacteria.
  5. Fungi are unicellular or multicellular eukaryotic organisms that are very common in the ecosystem but may be parasitic on higher organisms.
