Chapter 9 and 10

6. drugs that are effective against more than one group of bacteria
8. the growth of microorganisms in the blood and other tissues
10. chemical agents applied directly to exposed body surfaces, wounds, and surgical incisions to destroy or inhibit pathogens
13. energy emitted from atomic activities and dispersed at high velocity through matter or space
14. chemical that destroys bacteria except for those in the endospore stage
15. any practice that prevents the entry of infectious agents into sterile tissues and therefore prevents infection
18. method of preserving microorganisms and other cells in a viable state for many years
19. additions to the DNA taht do not change the gene but its expression
20. drugs that generally target a specific group

1. agents that prevent the growth of bacteria on tissues or on objects in the environment
2. solutions containing pure water as the solvent
3. shortest length of time to kill all test microbes at a specified temperature
4. drugs should kill or inhibit microbial cells without simultaneously damaging host tissues
5. principal treatment for malaria for hundreds of years
7. the lowest temperature required to kill all microbes in a sample in 10 minutes
9. preparations of live microorganisms that are fed to animals and humans to improve the intestinal biota
11. the ratio of the dose of the drug that is toxic to humans compared to its minimum effective dose
12. gene silencing
16. most frequent drug reactions
17. smallest concentration of drug that visibly inhibits growth
