  1. Sterilization And Disinfection G. Jamjoom

  2. STERILIZATION • All living things killed, • including spores

  3. Sterilization • autoclaving • 121oC (heat/pressure) • Heat resistant materials • ethylene oxide • Non heat resistant • usually equipment • ultra-violet light • surfaces (e.g operating rooms) • not totally effective

  4. Disinfection • Liquids that kill bacteria • e.g. phenol based • too toxic for skin surfaces

  5. Antiseptics • Topical (e.g. skin) • e.g. iodine or 70% alcohol • “reduce” bacterial load

  6. Methods of Sterilization

  7. Membrane filters pores bacteria

  8. Methods of Sterilization
