Across
- 4. the reaction of tissues to injury or infection

- 18. a spherical or oval bacterium
- 19. a spiral or corkscrew shaped bacterium that is slightly longer that a bacillus type
- 21. A disease that was carried by an immune carrier, Mary Mallon, in the early 1900s
- 27. a rod-shaped bacterium
- 28. the process in which a virus remains latent in cells but spreads by becoming part of the host cell genome
- 32. A disease that causes numbness and muscular deterioration
- 33. a virus that infects only certain bacteria
- 34. the ability of a virus to affect cells
- 35. another form of bacterial genetic transfer; occurs when living bacteria cells take up other bacteria's DNA
- 36. a submicroscopic, non-cellular particle, composed of nucleic acid core and a protein coat called the capsid; an obligate parasite
- 37. feeding on dead organic matter
- 38. located on the outside of a bacterial cell wall; made of gummy complex carbohydrates

- 8. Can both cure and cause cancer
- 9. used by some viruses; is made mostly of lipids
- 10. fission a type of asexual reproduction that does not involve the normal steps of mitosis, but the result is the same
- 12. a protein coat covering a virus cell's exterior
- 13. An abnormal growth of cells that is slow and localized

- 30. a special type of virus that contains the enzyme reverse transcriptase
- 31. a chemical produced by living organisms that naturally kills or inhibits the growth of other organisms
