Across
  1. 2. Outer protein coat of a virus
  2. 3. A small ring of DNA that carries accessory genes separate from those of the bacterial chromosome
  3. 5. allows substances to come in and out of the cell
  4. 6. protein particles that cause disease
  5. 7. Gram + bacteria- much peptidoglycan, purple stain, treat with.....
  6. 9. a substance that kills or prevents growth of other microorganisms
  7. 10. A virus that infects bacteria
  8. 15. bacteria that live in high salt environments
  9. 16. spreading of a pathogen
  10. 17. organisms that make their own food
  11. 22. redness, pain, swelling and heat that help destroy pathogens
  12. 25. organism that obtains food by consuming other living things
  13. 26. a disease that strikes people at the same time in the same area (flu season)
  14. 27. fibers Allow the virus to attach to the host cell
  15. 28. A tiny, nonliving particle that invades and then reproduces inside a host cell.
  16. 29. prevents that bacteria cell from bursting
  17. 33. a disease that spreads worldwide
  18. 35. outer structure of some viruses that make a virus easily hidden inside of the host
  19. 36. a poison that can harm an organism
  20. 37. bacteria that live in hot acidic environments
  21. 39. the short-term immunity that results from the introduction of antibodies from another person or animal. (rabies shot or mothers breast milk)
  22. 40. macrophages the engulf and destroy pathogens
Down
  1. 1. source of pathogen
  2. 4. Spiral bacteria
  3. 8. Acid DNA and RNA- genetic material
  4. 9. extremist bacteria that live where there is no oxygen
  5. 11. viral DNA that has attached to a host cell's chromosome and that is replicated with the chromosome's DNA
  6. 12. whip-like tail on bacteria used to create movement
  7. 13. structures that make proteins
  8. 14. cycle long viral cycle in which the viral DNA is added to the host cell's DNA and triggered to be released by stress
  9. 18. cycle short viral cycle in which copies of a virus are made within a host cell, the host cell dies and releases more viruses
  10. 19. Rod bacteria
  11. 20. hair-like structures that help bacteria stick to surfaces
  12. 21. Proteins secreted by cells infected with a virus. These proteins stimulate nearby cells to produce virus-fighting substances.
  13. 23. Gram - bacteria- little peptidoglycan, pink stain, treat with.....
  14. 24. Round bacteria
  15. 30. the immunity that results from the production of antibodies by the immune system in response to the presence of an antigen.
  16. 31. organism, such as a mosquito or tick, that transfers pathogens from one host to another
  17. 32. a disease that is always present in small amounts in a population (common cold)
  18. 34. bacteria that can live almost anywhere oxygen is available
  19. 38. outer covering of bacteria used for protection
  20. 39. An organism that causes disease
