• Sterilization


  Process of destroying all living organisms and viruses
• Disinfection


  Elimination of microorganisms
• Decontamination


  Treatment of an object to make it safe to handle
• Disinfectant


  An agent used to disinfect inanimate objects too toxic to use on human tissues
• Antiseptic


  An agent that kills or inhibits growth of microbes but is safe to use on human tissue
• Sanitizer


  An agent that reduces microbial numbers to a safe level
• Antibiotic


  Metabolic product produced by one microorganism that inhibits or kills other microorganisms
• Chemotherapeutic synthetic drugs


  Synthetic chemicals that can be used therapeutically
• Cidal

  Agent that will kill MCO in action
• Static


  Agent that will inhibit MCO in action (di pumapatay, prevent lang)
• Bactericidal


  Refers to killing bacteria
• Bacteriostatic


  Refers to inhibiting the growth of bacterial cells
• Bactericide


  Kills bacteria
• Fungicide


  Kills fungi
• Endospores of bacteria are considered the most thermoduric of all cells so their destruction guarantees sterility
• Incineration


  Burns organisms and physically destroys them
• Boiling


  Kills everything except some endospores
• Autoclaving


  Steam under pressure or pressure cooker (the most effective and most efficient means of sterilization)
• Usual standard temperature/pressure employed is 121°C/15 psi for 15 minutes
• Laboratory autoclave


  Used to sterilize microbiological culture medium
• Moist heat


  Kills microorganisms by causing denaturation of essential proteins
• Thermal Death Time (TDT)


  The time required to kill a known population of microorganisms in a specific suspension at a particular temperature
• Increase temp


  +TDT decreases
• Decrease temp


  -TDT increases
• Dry Heat


  Used for glassware, metal, and objects that won't melt
• Irradiation


  Usually destroys or distorts nucleic acids. Ultraviolet light is commonly used to sterilize the surfaces of objects, although x-rays, gamma radiation and electron beam radiation are also used
