Bacteria and Viruses

2. A medication made from very small amounts of weak or dead microorganisms that can cause diseases; stimulates immune system
6. Tiny infectious agent that is considered nonliving and requires a host cell to replicate itself
9. Describes the viral replication cycle that results in viral DNA being integrated into the host's DNA; cell death doesn't occur rapidly
11. A medication used to treat people who have already been infected by a virus; it can be used to prevent or limit infection
14. A virus that specifically infects bacteria
16. A virus that is known to cause respiratory diseases in humans
17. An organism that can produce its own food using light, water, carbon dioxide, or other chemicals
18. A medicine (such as penicillin) that inhibits the growth of or destroys microorganisms

1. Single-celled microorganisms that have cell walls, but lack membrane-bound organelles (i.e. nucleus).
3. Many antibiotics prevent the making of this structure found in bacteria
4. The membrane that forms the outer layer of some viruses
5. Describes the viral replication cycle that leads to immediate replication of the virus and host cell death
7. A jelly-like substance that provides a food and water source to bacteria
8. An organism that cannot produce its own food, relying instead on the intake of nutrition from other sources of organic carbon
10. A device used to grow and maintain microbiological cultures; maintains optimal temperature, humidity, and other conditions
12. A whip-like structure that allows a cell to move; found on prokaryotic and eukaryotic cells
13. A form of protection from infectious disease that occurs when most of the population is vaccinated
15. Describes viruses, bacteria, and other types of germs that can cause disease
19. Protein coat or shell of a virus particle; protects viral genome
