  1. 2. A medication made from very small amounts of weak or dead microorganisms that can cause diseases; stimulates immune system
  2. 6. Tiny infectious agent that is considered nonliving and requires a host cell to replicate itself
  3. 9. Describes the viral replication cycle that results in viral DNA being integrated into the host's DNA; cell death doesn't occur rapidly
  4. 11. A medication used to treat people who have already been infected by a virus; it can be used to prevent or limit infection
  5. 14. A virus that specifically infects bacteria
  6. 16. A virus that is known to cause respiratory diseases in humans
  7. 17. An organism that can produce its own food using light, water, carbon dioxide, or other chemicals
  8. 18. A medicine (such as penicillin) that inhibits the growth of or destroys microorganisms
Down
  1. 1. Single-celled microorganisms that have cell walls, but lack membrane-bound organelles (i.e. nucleus).
  2. 3. Many antibiotics prevent the making of this structure found in bacteria
  3. 4. The membrane that forms the outer layer of some viruses
  4. 5. Describes the viral replication cycle that leads to immediate replication of the virus and host cell death
  5. 7. A jelly-like substance that provides a food and water source to bacteria
  6. 8. An organism that cannot produce its own food, relying instead on the intake of nutrition from other sources of organic carbon
  7. 10. A device used to grow and maintain microbiological cultures; maintains optimal temperature, humidity, and other conditions
  8. 12. A whip-like structure that allows a cell to move; found on prokaryotic and eukaryotic cells
  9. 13. A form of protection from infectious disease that occurs when most of the population is vaccinated
  10. 15. Describes viruses, bacteria, and other types of germs that can cause disease
  11. 19. Protein coat or shell of a virus particle; protects viral genome
