Across
- 3. results when a disease causing organism invades and begins growing within another organism
- 4. Organisms that are infectious and cause disease
- 8. larger agents visible to the naked eye.
- 12. An organism in which another organism lives.
- 15. The number of organisms it takes to cause illness following exposure
- 16. infectious proteins
- 20. a sudden increase in the number of cases of a disease in a population
- 22. type of acquired immunity that is given from the mother. Antibodies are given to a child through the placenta or through breast feeding.
- 24. sequence of events following the spread of. an infection
- 25. living, eukaryotic, single-celled organism; commonly called a parasite
- 26. occurs if and when the invasion and growth of a pathogen impair bodily functions.
- 28. diseases are contracted, or caught
- 29. a substance that contains a weakened or killed form of a pathogen, or just a part of a pathogen to stimulate an immune response
- 31. a disease that occurs infrequently and irregularly
- 32. tiny agents, called microbes, visible only with a powerful microscope
- 33. An epidemic that has spread across several countries or continents and affects a large number of people.
- 34. A protein produced by B cells in the blood; works to impair pathogens
- 37. A sudden increase in the occurrence of a disease in a localized area.
- 38. A single-celled, prokaryotic microorganism.
- 39. one that is vulnerable to infection.
Down
- 1. Disease transmission that occurs when a susceptible host touches an infected individual or is exposed to their body fluids.
- 2. non-living organism that needs to infect a host cell to replicate
- 5. Non-specific immune defense mechanisms that we are born with. These mechanisms work to keep anything outside of us from coming in.
- 6. the types of organisms that cause disease
- 7. type of acquired immunity following infection and recovery, or from a vaccine. Your body makes its own antibodies.
- 9. Specific immune defense mechanisms that uses antibodies to respond to specific antigens
- 10. hospital-acquired infection (HAI).
- 11. A large, eukaryotic, multicellular, parasitic worm
- 13. spore producing eukaryotic organisms
- 14. A foreign invader that stimulates an immune response.
- 17. Disease transmission that occurs when a susceptible host inhales infected particles, touches an infected object, or is bitten by an infected insect.
- 18. a form of artificially acquired immunity that occurs when the majority of a population, but not all, has been given a vaccine and becomes resistant to infection
- 19. A disease perpetually present in a community or population within a specific geographic area.
- 21. health care expert who study trends in health issues in populations
- 23. where the agent of disease previously resided
- 27. white blood cells that kill the pathogen by secreting toxins or by ingesting and digesting the toxins
- 30. The ability to defend against a pathogen by preventing its entry and/or development or by neutralizing its pathogenic cellular products.
- 35. white blood cells that matures in bone marrow and produces antibodies.
- 36. flora The bacteria that live in us and on us
