  1. 5. gamma rays & x rays and are very penetrating
  2. 7. chemical agent that kill microorganisms
  3. 8. shortest length of time required to kill all test microbes at a specified temperature
  4. 11. effective for heat resistant materials such as glassware, clothes, metallic instruments , liquids , some media etc.
  5. 13. hot air or open flame , which range from 2160- to several thousands of degrees Celsius
  6. 14. chemicals can be liquid, gaseous , solid state . range from disinfections and antiseptics, to sterilant and preservation

  1. 1. chemical that destroys bacteria except for endospores
  2. 2. do not tough the patient or only touch intact skin and require low level disinfection
  3. 3. hot water, boiling water, or steam between 60-135 degrees Celsius
  4. 4. merely slows the activities of most microbes
  5. 6. agents are typically "killing agents" depending on how they are used
  6. 9. permanent termination of an organism vital processes with permanent loss of reproductive capability
  7. 10. vegetative cells directly exposed to normal room temperature gradually become dehydrated . Many microbes are not killed and some are even preserved
  8. 12. vary in sensitivity to heat, depending on microbe type
