  1. Sterilization
    Kills or removes all forms of living organisms
  2. Pasteurization
    Heat is applied to liquids; most viruses are inactivated; 98% of bact and fungi are killed. Some pathogens may survive.
  3. Scrubbing
    Removes many microbes mechanically.
  4. Boiling
    For 30 min. kills all vegetative forms of pathogenic bacteria; spores survive; some non-pathogens survive.
  5. X-rays
    In specific doses kills microbes; used to steralize medical items and food.
  6. Disinfectant
    Destroys vegetative cells of pathogens; does not kill spores; irritating or harmful to living tissue.
  7. Antiseptic and Bacteriostatic
    Kills or inhibits vegetative cells of pathogens but not spores.
  8. Germicide
    Kills bact but only those mentioned on product label.
  9. Asepsis
    Those practices that prevent the entry of infectious agents into sterile tissues.
  10. Ethyl or Isopropyl alcohol
    Good disinfectant; does not kill spores; inexpensive.
  11. Cidex (sonacide)
    Kills bact, spores, and viruses; used on objects; high oder.
  12. An iodine compound used on skin and objects; kills bact, fungi, ameoba and viruses.
    Betadine
  13. Hibiclens
    Hand disinfectant
  14. Wavecide
    Table disinfectant
  15. Fungicides
    Kill fungi including their spores
  16. Halt or hinder viral multiplication
    Antivirals
